JUSTICE STEIGMANN delivered the opinion of the court:

In August 2002, a jury convicted defendant, Maurice Durgan, of (1) one count of possession of a substancecontaining cocaine (720 ILCS 570/402(c) (West 2000)) and (2) one count of possession of more than 1 gram but not morethan 15 grams of a substance containing cocaine with intent to deliver (720 ILCS 570/401(c)(2) (West 2000)). In October2002, the trial court sentenced him to eight years in prison on the possession-with- intent-to-deliver conviction. (Thecourt did not enter judgment on the other conviction, having determined that it merged into defendant's conviction forpossession with intent to deliver.)

Defendant appeals, arguing that (1) the stipulated testimony of a forensic chemist was inadequate to establishthat (a) an adequate foundation existed for the chemist's testimony and (b) the chemist tested all of the individuallywrapped packets of cocaine found in defendant's possession; (2) the State did not establish a proper chain of custodyfor the seized cocaine; (3) the trial court erred by (a) replacing a sick juror with an alternate juror after the jury begandeliberating and (b) relying on evidence outside the record in denying his posttrial motion; (4) the State failed to provehim guilty beyond a reasonable doubt; and (5) he received ineffective assistance of trial counsel. We disagree and affirm.

In February 2001, the State charged defendant with (1) one count of possession of a substance containingcocaine (720 ILCS 570/402(c) (West 2000)) and (2) one count of possession of more than 1 gram but not more than 15grams of a substance containing cocaine with intent to deliver (720 ILCS 570/401(c)(2) (West 2000)).

Following an October 2001 trial, a jury convicted defendant of both charges. In November 2001, defendant fileda motion for a new trial. At a January 2002 hearing on that motion, defense counsel argued facts from a different case. The trial court then sua sponte found that defense counsel provided ineffective assistance and granted defendant'smotion for a new trial.

At the start of defendant's August 2002 retrial, the bailiff informed the trial court that one of the jurors (referredto in the record only as Mr. Gilpin) had been sick the previous night. The bailiff instructed Gilpin to let the court knowif he felt sick, and the court proceeded with defendant's trial.

Danville police officer Troy Wasson testified that he had (1) been an officer since 1996, (2) attended five trainingseminars on drug enforcement, and (3) been involved in at least 50 drug cases. Around 3 p.m. on December 15, 2000,he went to an apartment located at 915 Redden Court in Danville to execute a search warrant. While Wasson and otherofficers waited outside the apartment for the "target person" (an individual other than defendant) to arrive, Wasson sawdefendant standing either just outside or in the front doorway. When the officers approached the apartment to beginthe search, defendant yelled "police" and went inside the apartment. Officers arrested defendant and six otherindividuals as they left the apartment through its back door and later took them to the Danville public safety building. Officers searched the apartment and found cannabis and cocaine.

When Wasson arrived at the public safety building, Danville police officer John Thompson handed him a clearplastic bag that contained individual packages (plastic Baggie corners that were tied off) containing a substance thatthe officers suspected was crack cocaine. (Thompson found the plastic bag in a trash can near where defendant hadbeen sitting in the "book-in" area prior to being searched.) Although Wasson initially testified that the plastic bagcontained 19 individually wrapped packages, he later testified that it contained either 18 or 19 individually wrappedpackages. Wasson secured the plastic bag containing the individually wrapped packages and later handed it to Danvillepolice officer Ron Soderstrom, who processed it as evidence. Wasson denied tampering with the plastic bag.

Wasson opined that the individually wrapped packages were intended for sale. He explained that based on histraining and experience, "a normal user or addict of crack cocaine wouldn't carry that amount of crack cocaine on them." Wasson stated that he would not change his opinion if the larger plastic Baggie contained 18 individually wrappedBaggies, not 19.

Thompson testified that after officers transported defendant to the public safety building, Thompson sat himon the floor beside a bench, where three other individuals were handcuffed. Thompson and a correctional officer thenescorted the individuals, including defendant, one by one to another room and searched them. Thompson then searchedthe book-in area. At the top of the trash in a trash can that was located about 3 1/2 feet from where defendant had beensitting, Thompson found a clear plastic bag that contained several individually wrapped packages of an "off-white[,]rock-like substance." Thompson took the bag as evidence and gave it to Wasson. He had the bag for only a coupleof minutes, just long enough to walk up one flight of stairs and hand it to Wasson. Thompson denied counting theindividual packages or tampering with the plastic bag.

Soderstrom testified (through the trial court's admission of a transcript of his testimony at defendant's first trial)that when items are recovered, officers immediately label them with the time, location, and the name of the officer whorecovered them. On the day Wasson gave him the plastic bag, Soderstrom weighed it, filled out an inventory tagdescribing the bag and its contents, and placed the plastic bag in a paper bag. He then labeled the paper bag with theDecember 15, 2000, recovery date, the police report number, his and Wasson's badge numbers, sealed it, initialed thelabel, and placed the paper bag in an evidence locker. Soderstrom placed the key to that evidence locker, along with ayellow duplicate inventory tag, in another locker, to which only the evidence officer had access. He identified People'sexhibit No. 1 as the paper bag that contained the clear plastic bag containing individually wrapped packages. Soderstromexplained that he recognized his handwriting on the property tag and recalled filling out that tag for that specific pieceof evidence on December 15, 2000.

Danville police officer Larry Thomason, the evidence officer, testified that when an officer recovers an item, heplaces it in an appropriate-sized container and seals the container. The officer places various identifying markings onthe container and attaches a property tag (1) indicating the police report number, the name of the officer, and the offenseand (2) describing the contents of the container. The officer then places the container in an evidence locker and putsthe locker key in another locker, to which only Thomason and his assistant have access.

Thomason identified People's exhibit No. 1 as the paper bag that contained the clear plastic bag containingindividually wrapped packages. He also identified a white form with a red sticker on it that was attached to exhibit No.1 as the inventory tag. A yellow duplicate of that inventory tag was attached to the locker key for the locker in whichPeople's exhibit No. 1 had been stored. On December 19, 2000, Thomason retrieved the paper bag (People's exhibit No.1) from the evidence locker, took it to the evidence room, and placed it in a storage bin. When he retrieved the paper bag,it was sealed, and the white inventory tag was attached to it with staples. Thomason entered the information from theinventory tag into a computer program that tracked the evidence's whereabouts. On December 27, 2000, he wrote thedate and his initials on the paper bag and sent it to the Illinois State Police crime laboratory by certified mail. WhenThomason placed it in the mail, the paper bag was still sealed. On February 1, 2001, he picked up the bag from the crimelaboratory and returned it to the original storage area in the public safety building. When Thomason picked up the bag,it was sealed with blue tape from the laboratory. Thomason denied opening the paper bag or tampering with it.

The testimony of Kristin Stiefvater, an Illinois State Police forensic chemist, was presented via a stipulation thatthe parties agreed upon and the trial court accepted. That stipulation, which the prosecutor read to the jury, providedas follows:

"[Stiefvater] would testify that she is a trained, experienced forensic scientist in the Springfield [c]rime[l]aboratory.

That on December 28th, 2000, she received People's [e]xhibit [No.] 1 in a sealed condition.

That she tested the contents of People's [exhibit No.] 1.

That she determined People's [exhibit No.] 1 to contain 18 plastic [B]aggies.

Contents of the plastic [B]aggies contained 1.8 grams of off-white chunk substance, being the netweight of chunky substance, cocaine being present as the base[,] in her opinion, based upon her training andtesting and experience.

That after testing People's [e]xhibit [No.] 1 and its contents[,] she resealed it and returned it to[Thomason] in a sealed condition."

Danville police officer Mike Cox testified that on the evening of December 15, 2000, he interviewed defendantat the public safety building. After waiving his Miranda rights (Miranda v. Arizona, 384 U.S. 436, 16 L. Ed. 2d 694, 86 S.Ct. 1602 (1966)), defendant told Cox that earlier that day, he had been at 915 Redden Court to "chill[] out" and do "a littlegambling." Defendant admitted that when officers arrested him and took him to the book-in area, he had a "real skinny,rolled up blunt" in his jacket pocket and a "few bags" of crack cocaine hidden in his underwear. While sitting in thebook-in area, he threw the cocaine in a nearby trash can. He told Cox that he used cocaine "every blue moon" and thecocaine he threw in the trash can was for his personal use. Specifically, defendant used the cocaine to make a "premoblunt." Cox explained that (1) a "blunt" is made by cutting a cigar lengthwise, removing the inner tobacco and replacingit with cannabis, and then rolling the outer tobacco leaves back together so that it looks like a thinner cigar; and (2) a"premo" blunt is one that has been laced with cocaine.

On this evidence, the State rested, and defendant presented no witnesses. After the trial court instructed thejury, it asked Gilpin if he was well enough to participate in deliberations. Gilpin responded that he felt well enough, andat 11:45 a.m., the court instructed the jury to leave the courtroom and begin deliberations. The court also asked thealternate juror (referred to in the record only as Ms. Lewis) to stay in the courtroom. The following discussion then tookplace outside the jury's presence:

"THE COURT: Okay. Ms. Lewis, normally I would discharge you completely from further servicesince we have the other 12 that are going back to begin deliberations. What I'd like to do, however, in yourparticular case[,] is I'm going to release you, but I'm going to ask that you still not talk with anyone about thecase. Leave your notebook here. There is the remote possibility that we would then reenlist your services if[,]for some reason[,] Mr. Gilpin cannot make it through deliberations.

All right. So although you'll be released to leave and, in fact, if--what we could do is since we're goingto be probably ordering lunch if you want to wait here we'll get lunch for you as well. And you're welcome tohave that lunch. You can't eat with the rest of the jurors or anything like that, but we can put you somewhereelse.

MS. LEWIS: Okay.

THE COURT: We'll just ask that you not talk with anyone about the case or discuss the case in anyway until we know whether they are able to reach a verdict and whether Mr. Gilpin is going to be able tocomplete his service, because if he's not[,] then there is that possibility that you would have to go in and begin[sic] part of deliberations.

Any other instructions that counsel wishes for Ms. Lewis?

[PROSECUTOR]: Just that she leave with the clerk some way of contacting her if we need her.

THE COURT: We need a telephone number, cell phone number, something.

MS. LEWIS: I don't have a telephone. I live in Georgetown, so I'll stay here.

THE COURT: If you'll leave your telephone number[,] then when the clerk--

MS. LEWIS: I can just go home you mean?

THE COURT: Sure.

MS. LEWIS: Okay. Okay.

THE COURT: You're welcome to wait here till lunch is delivered and have lunch, if you wish, or you'rewelcome to take it with you and then go home, but it's just a little unusual. Mr. Gilpin said he's indicated he wassick all last evening. And if there is the possibility that he's not going to be able to complete service then wewould need you. So I'm not going to discharge you completely from any possible service.

Okay. Anything else for Ms. Lewis?

[PROSECUTOR]: No, your Honor.

[DEFENSE COUNSEL]: No, your Honor.

THE COURT: Okay."

Lewis then left the courtroom.

At 12:30 p.m., 45 minutes after the jury left the courtroom to begin deliberations, the trial court was informedthat Gilpin was too ill to continue serving as a juror. The following discussion then took place outside the jury'spresence:

"[THE COURT]: We've retained [Lewis]. She is still available. She's been isolated and separated fromthe other jurors, but is immediately available to take Mr. Gilpin's place.

After discussions *** with the attorneys, [prosecutor], do you have any objection to replacing Mr.Gilpin with the alternate, Ms. Lewis?

[PROSECUTOR]: No, your Honor.

THE COURT: And [defense counsel], any objection?

[DEFENSE COUNSEL]: No, I don't, your Honor."

The court then excused Gilpin as a juror and replaced him with Lewis.

After deliberating between 4 and 4 1/2 hours, the jury convicted defendant of both charges, and the trial courtentered judgment only on the conviction for possession of more than 1 gram but not more than 15 grams of a substancecontaining cocaine with intent to deliver (720 ILCS 570/401(c)(2) (West 2000)). The court later sentenced defendant asstated.

This appeal followed.

A. The Adequacy of the Forensic Chemist's Stipulated Testimony

1. Foundation for Stiefvater's Expert Opinion

Defendant first argues that the State failed to provide an adequate foundation for Stiefvater's expert opinionthat the substance found in defendant's possession contained cocaine. Specifically, he contends that Stiefvater'sstipulated testimony did not show (1) what tests Stiefvater performed on the substance; (2) whether those tests were"commonly used in the area of forensic chemistry"; (3) how Stiefvater recorded her findings; and (4) whether theequipment she used in testing the substance was functioning properly. Defendant further claims that because hisargument attacks the sufficiency of the evidence, his argument is not subject to forfeiture. We disagree.

Initially, we reject defendant's attempt to couch his foundational argument as a challenge to the sufficiency ofthe evidence. In People v. DeLuna, 334 Ill. App. 3d 1, 20, 777 N.E.2d 581, 598 (2002), the First District held that an attackas to the proper foundation for expert testimony bears on the admissibility of the evidence rather than the sufficiencyof the evidence to convict. The First District explained as follows:

"Arguably, sufficiency involves absence of proof of a basic element of the crime. Defendant here is notchallenging the lack of proof as to the existence of an element of the crime, since [the expert] testified to theidentity of the controlled substance. The challenge is to the failure to lay a proper foundation for the proof ofthat element. This goes to a determination of its admissibility, rather than sufficiency of the evidencepresented." DeLuna, 334 Ill. App. 3d at 20, 777 N.E.2d at 598.

We agree with DeLuna and thus reject defendant's attempt to re-characterize his foundational argument as a challengeto the sufficiency of the evidence. See People v. Besz, 345 Ill. App. 3d 50, 54-55, 802 N.E.2d 841, 845-46 (2003) (relyingon DeLuna and rejecting the defendant's attempt to recharacterize a foundational argument as a sufficiency-of-the-evidence claim); see also People v. Hill, 345 Ill. App. 3d 620, 632, 803 N.E.2d 138, 148 (2003) (adhering to DeLuna andBesz).

In Hill, 345 Ill. App. 3d at 630-33, 803 N.E.2d at 147-49, the First District recently addressed a defendant'sfoundational challenge to expert testimony to which the defendant stipulated. The court held that a defendant whostipulates to an expert's opinion at trial forfeits his right to challenge on appeal the foundation for the expert's opinion. Hill, 345 Ill. App. 3d at 630, 803 N.E.2d at 147. In so holding, the court reasoned that a defendant forfeits any issue asto the impropriety of evidence if he procures, invites, or acquiesces in the admission of that evidence. Hill, 345 Ill. App.3d at 631, 803 N.E.2d at 147. The Hill court also stated, in pertinent part, as follows:

"[S]everal characteristics unique to stipulations further support our holding. First, had [the] defendant madea timely objection at trial and not agreed to the State's stipulation, the trial court could have addressed thisfoundational issue and the State could have corrected the deficiency. [Citation.] By presenting the chemist'stestimony through a stipulation, in a brief and summary fashion, the result was to remove from the case anyissue concerning the expert's testimony. [Citation.] See also People v. Polk, 19 Ill. 2d 310, 315, 167 N.E.2d 185,188 (1960) (finding that the 'stipulation had the effect of eliminating proof which otherwise might have beenrequired'). Additionally, the State likely would not have agreed to the stipulated testimony, thereby foregoingthe opportunity to place the expert on the witness stand and ask him to describe in detail the number and typeof tests performed on the substance, if the stipulation was not intended to eliminate the need for defending histestimony against a challenge by defendant. [Citation.] Further, we assume that defense counsel, by agreeingto the stipulation, decided to forego the opportunity to cross-examine the expert to focus on other theories andaspects of the defense." Hill, 345 Ill. App. 3d at 632, 803 N.E.2d at 148.

We fully agree with the Hill court's holding and reasoning. We further note that by stipulating to a fact--forexample, as in this case, that the substance tested was cocaine--the parties dispense with the need to further stipulateto the foundation underlying that fact. In other words, because a stipulation is a substitute for the witness's actualtestimony, all of those matters that the witness could have and should have testified about are encompassed by thestipulation. Thus, if a defendant and the State agree to stipulate that the forensic chemist tested a substance anddetermined its weight and content, they eliminate any issue as to that expert's testimony, such as (1) the expert'squalifications, (2) what tests she performed on the substance, (3) whether the tests actually performed were of a typegenerally accepted and relied upon in the field, and (4) whether the equipment used to perform the tests was functioningproperly when the tests were performed. We note, however, that by stipulating to a witness's testimony, the parties donot stipulate to matters that are not necessarily implicated by the stipulation. For instance, in this case, where thestipulation was meant to take the place of the forensic chemist's testimony, the stipulation did not encompass the chainof custody up to the time the forensic chemist received People's exhibit No. 1.

Accordingly, under the circumstances of this case, we conclude that because defendant stipulated toStiefvater's expert testimony that the substance contained 1.8 grams of cocaine, he cannot challenge on appeal thefoundation for Stiefvater's testimony.

In so concluding, we note that although stipulations are to be encouraged, clarity and precision of thoughtshould be encouraged as well. These goals can be obtained by ensuring that the stipulation to which the parties agreeis both accurate and complete. For example, in this case, it would have been better practice if the trial court had takenthe following steps:

(1) The court should have assured that the stipulation explicitly stated that (a) Stiefvater received People'sexhibit No. 1, which contained 18 individually wrapped packages containing an off-white chunky substance; (b)Stiefvater tested all 18 packages; and (c) Stiefvater's testing determined that the 18 packages contained a total of 1.8grams of cocaine.

(2) The court should have required the stipulation to be reduced to writing and then required the parties toagree to the written stipulation. If necessary, the court itself should have written the stipulation.

(3) To avoid any uncertainties as to the scope of the stipulation, the court should have made clear on the recordexactly what the stipulation encompassed and what it did not encompass. In particular, the court should have noted thatthe stipulation eliminated any issue as to Stiefvater's testimony but did not address any chain-of-custody issue.

(4) Finally, the court should have informed the jury that the parties agreed upon a stipulation, and then thecourt should have read the stipulation to the jury.

We further note that defendant's reliance on People v. Raney, 324 Ill. App. 3d 703, 756 N.E.2d 338 (2001), ismisplaced. In that case, the appellate court concluded that the State failed to establish a proper foundation for theadmission of the results from a gas chromatography mass spectrometer machine used to test the substance in a drug-possession-with-intent-to-deliver case. Based on that deficiency, the appellate court reversed the defendant'sconviction. Raney, 324 Ill. App. 3d at 704-05, 756 N.E.2d at 339. However, the forensic chemist in Raney actually testifiedat trial. In addition, defense counsel in Raney repeatedly challenged the foundation at trial. Raney, 324 Ill. App. 3d at705, 756 N.E.2d at 340. Thus, Raney is simply not applicable to this case, where the parties stipulated to the forensicchemist's testimony. See Hill, 345 Ill. App. 3d at 630-31, 803 N.E.2d at 147; Besz, 345 Ill. App. 3d at 54, 802 N.E.2d at 845;see also People v. Washington, 343 Ill. App. 3d 889, 900, 800 N.E.2d 436, 444 (2003) (all determining that Raney wasdistinguishable because it did not involve stipulated evidence).

As a final matter, we reject defendant's reliance on People v. Ortega, 83 Ill. App. 2d 49, 226 N.E.2d 426 (1967),to support his assertion that the stipulation was required to include "the same foundational requirements as would berequired had Stiefvater actually testified." In support of that proposition, he specifically cites the following from Ortega:

"[W]e have been impressed by numerous instances in recent years of the demonstrated nonchalanceand inattention to detail on the part of prosecutors when introducing by stipulation the part of the State's casehaving to do with the chain of possession and chemical content of the substance seized in narcotics cases. The expedience of resorting to such a stipulation we do not doubt, but we cannot permit this informality ofprocedure to render the proof any less exact or complete than would be the case if the witnesses were totestify." Ortega, 83 Ill. App. 2d at 51, 226 N.E.2d at 427.

First, we note that Ortega did not involve a defendant's foundational challenge to an expert's testimony. Instead, it addressed whether a stipulation was sufficient when it stated that a substance "'purport[ed] to be'" heroin,rather than that it "was 'found to be'" heroin. Ortega, 83 Ill. App. 2d at 51, 226 N.E.2d at 427. Further, to the extent Ortegacan be construed as holding that when parties stipulate to a forensic chemist's testimony as to the weight and contentof a tested substance, the stipulation must explicitly include the same foundational elements as when the chemist actuallytestifies, we expressly reject it and decline to follow it.

Accepting defendant's proposition and holding that a forensic chemist's stipulated expert opinion must includeevery foundational element required when a chemist testified at trial would serve no purpose other than to discouragestipulations, which we refuse to do. In this regard, we reiterate what this court wrote in People v. Calvert, 326 Ill. App.3d 414, 420, 760 N.E.2d 1024, 1029 (2001):

"A stipulation is 'an agreement between parties or their attorneys with respect to business before a court'(People v. Buford, 19 Ill. App. 3d 766, 770, 312 N.E.2d 796, 799 (1974)), and courts look with favor uponstipulations because '"they tend to promote disposition of cases, simplification of issues[,] and the saving ofexpense to litigants"' (People v. Coleman, 301 Ill. App. 3d 37, 48, 704 N.E.2d 690, 698 (1998), quoting In re Estateof Moss, 109 Ill. App. 2d 185, 192, 248 N.E.2d 513, 516 (1969))."
 

2. The Testing of All Individually Wrapped Packages

Defendant also argues that Stiefvater's stipulated testimony was insufficient to prove that she tested thecontents of all 18 individually wrapped packages. We disagree.

"'A stipulation is to be given its natural and ordinary meaning.'" People v. Horton, 143 Ill. 2d 11, 21, 570 N.E.2d320, 324 (1991), quoting People v. Joe, 31 Ill. 2d 220, 226, 201 N.E.2d 416, 419 (1964). In this case, Stiefvater's stipulatedtestimony provided that (1) Stiefvater received People's exhibit No. 1 (which was the clear plastic bag containing theindividually wrapped packages) in a sealed condition; (2) she determined that People's exhibit No. 1 contained 18 plasticBaggies; (3) she tested the contents of People's exhibit No. 1; and (4) the contents of the plastic Baggies contained "1.8grams of off-white chunk substance, being the net weight of chunky substance, cocaine being present as the base." Giving the stipulation its natural and ordinary meaning, we conclude that it adequately shows that Stiefvater tested all18 of the individually wrapped packages.

Moreover, to the extent that the stipulation could be viewed as ambiguous regarding whether Stiefvater testedall 18 packages, defense counsel cured any ambiguity during the following colloquy that took place outside the jury'spresence and after the stipulation was read to the jury:

"[DEFENSE COUNSEL]: There is--there is one other matter I wanted to just--I want to inform the courtso the court is aware of it, I have examined a transcript of the lab witness's testimony, [and it] does appear fromthe transcript at the previous trial that she had tested all 18--

[PROSECUTOR]: Yes.

[DEFENSE COUNSEL]: --[B]aggies. And so we weren't--there had been an attack available in the caselaw concerning whether this had been selective testing as far as the gram weight of things[,] and I was awareof [that] at the time I made the stipulation.

THE COURT: All right. Thank you.

[PROSECUTOR]: If she had testified[,] I would have brought that out, but--

[DEFENSE COUNSEL]: Yes."

In light of defense counsel's express concession that Stiefvater tested all 18 individually wrapped packages,we conclude that defendant cannot now challenge the stipulation on the ground that it failed to so indicate. See Peoplev. Caffey, 205 Ill. 2d 52, 114, 792 N.E.2d 1163, 1202 (2001) (when a party procures or invites the admission of evidence,he cannot challenge on appeal the admission of that evidence).

B. Defendant's Claim That the State Failed To Establish a Proper Chain of Custody

Defendant also argues that the State failed to establish a proper chain of custody for the admission of People'sexhibit No. 1 (the clear plastic bag containing 18 individually wrapped packages of cocaine) because (1) a discrepancyexisted as to the number of individually wrapped packages seized by Thompson and the number tested by Stiefvater and(2) no witness testified as to what inventory number was assigned to People's exhibit No. 1. We disagree. Before the trial court may admit real evidence at trial, the State must provide an adequate foundation either byway of live testimony or stipulation that establishes that (1) the item sought to be admitted is the actual item involvedin the alleged offense and (2) the item's condition is substantially unchanged. If an item is not readily identifiable or issusceptible to alteration by tampering or contamination, the State must establish its chain of custody with sufficientcompleteness to render it improbable that the original item has either been exchanged, contaminated, or tampered with. People v. Fox, 337 Ill. App. 3d 477, 481, 786 N.E.2d 563, 567 (2003).

Unless the defendant produces actual evidence of tampering, substitution, or contamination, the State needonly establish a probability that tampering, substitution, or contamination did not occur, and any deficiencies go to theweight rather than the admissibility of the evidence. People v. Herrero, 324 Ill. App. 3d 876, 882, 756 N.E.2d 234, 241(2001).

The purpose of protective measures is to ensure that the substance recovered from the defendant was the sameone as the substance tested by the forensic chemist. Fox, 337 Ill. App. 3d at 481-82, 786 N.E.2d at 567. Proof of delivery,presence, and safekeeping demonstrate that reasonable measures were taken to protect the evidence. People v. Gibson,287 Ill. App. 3d 878, 882, 679 N.E.2d 419, 422 (1997). The State is not required to exclude every possibility of tampering,nor does it need to present every individual involved in the chain of custody. Fox, 337 Ill. App. 3d at 482, 786 N.E.2dat 567.

In this case, defendant did not produce actual evidence of tampering, substitution, or contamination. Thus,the State had the burden to prove the chain of custody with sufficient completeness to establish a probability that (1)reasonable measures were employed to protect the evidence from the time it was seized and (2) it was improbable theevidence was altered. Fox, 337 Ill. App. 3d at 481, 786 N.E.2d at 567.

Having thoroughly reviewed the record, we conclude that the State proved the chain of custody with sufficientcompleteness to establish a probability that (1) the police used reasonable measures to protect People's exhibit No. 1 fromthe time Thompson retrieved it from the trash can until Stiefvater received it and (2) it was improbable that People'sexhibit No. 1 was altered or substituted. In so concluding, we reject defendant's contention that a discrepancy in thenumber of individually wrapped packages seized versus the number tested rendered the State's chain of custodyinsufficient. Although Wasson initially testified that the clear plastic bag contained 19 individually wrapped packages,he later testified that the total was either 18 or 19. Thus, his final testimony on that issue did not result in a discrepancyas to the number of individually wrapped packages that was fatal to the State's chain of custody. Instead, anydiscrepancy simply went to the weight of the evidence. See People v. Carroll, 227 Ill. App. 3d 144, 147-48, 590 N.E.2d1010, 1013 (1992) (Baggies of cannabis were admissible despite police officer's unclear and inconsistent testimony as tothe number of Baggies recovered and processed as evidence).

Nor do we agree with defendant that the lack of testimony as to the specific inventory number assigned toPeople's exhibit No. 1 rendered the State's chain-of-custody evidence insufficient. In this regard, we note thatSoderstrom identified the inventory tag he filled out for People's exhibit No. 1, which was attached to the paper bag whenhe placed it in the evidence locker. Further, as earlier stated, Soderstrom identified exhibit No. 1 based on (1) hishandwriting on the inventory tag and (2) his recollection of filling out the tag for that particular item of evidence. Thomason also identified People's exhibit No. 1 and the inventory tag that was still attached to it after it had been sentto, and returned by, Stiefvater. This evidence was sufficient to establish a reasonable probability that the evidence wasnot altered or substituted. See Herrero, 324 Ill. App. 3d at 882, 756 N.E.2d at 241.
 

C. The Trial Court's Juror-Replacement Procedure

Defendant next argues that the trial court erred by replacing Gilpin with Lewis after the jury began deliberating. Specifically, he contends that the court violated section 115-4(g) of the Code of Criminal Procedure of 1963 (725 ILCS5/115-4(g) (West 2000)) and Supreme Court Rule 434(e) (134 Ill. 2d R. 434(e)), both of which provide, in pertinent part,that "[i]f before the final submission of a cause," a juror dies or is discharged, the trial court shall replace him with analternate juror. Defendant also asserts that the court compounded its error by failing to (1) ascertain whether Lewis haddiscussed the case with anyone or formed an opinion and (2) instruct the jury to begin its deliberations anew. Defendantconcedes that by failing to raise a timely objection at trial or in his posttrial motion, he has forfeited this issue on appeal. Nonetheless, he urges us to review it under the plain-error rule.

Our supreme court has addressed the issue of plain error as follows:

"'"[B]efore an appellate court can correct an error not raised at trial, there must be (1) 'error,' (2) that is 'plain,'and (3) that 'affect[s] substantial rights."' [Citation.] If all "three conditions are met, an appellate court may thenexercise its discretion to notice a forfeited error, but only if (4) the error seriously affects the fairness, integrity,or public reputation of judicial proceedings."'" People v. Crespo, 203 Ill. 2d 335, 348, 788 N.E.2d 1117, 1124(2001), quoting United States v. Cotton, 535 U.S. 625, 631, 152 L. Ed. 2d 860, 868, 122 S. Ct. 1781, 1785 (2002),quoting Johnson v. United States, 520 U.S. 461, 467, 137 L. Ed. 2d 718, 727, 117 S. Ct. 1544, 1549 (1997).

See People v. Keene, 169 Ill. 2d 1, 17, 660 N.E.2d 901, 909-10 (1995) ("Plain error marked by 'fundamental [un]fairness'occurs only in situations which 'reveal breakdowns in the adversary system,' as distinguished from 'typical trial mistakes' [Citation.]").

This court will take our supreme court at its word and find plain error only in exceptional circumstances in which"'"the error seriously affects the fairness, integrity, or public reputation of judicial proceedings."'" Crespo, 203 Ill. 2d at348, 788 N.E.2d at 1124, quoting Cotton, 535 U.S. at 631, 152 L. Ed. 2d at 868, 122 S. Ct. at 1785, quoting Johnson, 520 U.S.at 467, 137 L. Ed. 2d at 727, 117 S. Ct. at 1549. The alleged error in this case falls far short of this standard. In soconcluding, we note that (1) Lewis (a) was subject to the same selection procedure as the other jurors, (b) took the sameoath as the other jurors, and (c) heard the evidence and was instructed on the law; (2) the trial court explicitlyadmonished Lewis that (a) it was not completely discharging her as an alternate juror and (b) she should not talk withanyone about the case until the court knew whether Gilpin could complete his service; (3) defense counsel had noobjection to, or concern about, the court's juror-replacement procedure; (4) Lewis had been released for only 45 minutesbefore being recalled; (5) although the record does not show where Lewis spent those 45 minutes, it does indicate that(a) during that time, she was "isolated and separated from the other jurors" and (b) when Gilpin could not continue, Lewiswas "immediately available"; (6) after Lewis replaced Gilpin, the jury deliberated for almost 4 1/2 hours before reachinga verdict; and (7) nothing in the record shows that Lewis (a) had impermissible contact with an outsider that prejudiceddefendant, (b) was coerced by a jury that had already come to a decision, or (c) was unable or unwilling to render a fairdecision.

We find support for our decision in People v. Henderson, 45 Ill. App. 3d 798, 359 N.E.2d 909 (1977). In that case,the defendant was tried before a jury of 12 regular and 2 alternate jurors. After instructing the jury, the trial courtdischarged the two alternate jurors, and the remaining jurors began deliberating. About 2 1/2 hours after deliberationsbegan, one of the jurors suffered a heart attack. The court stopped deliberations and recalled the two alternate jurors. The court then questioned the alternate jurors about their activities during the 2 1/2-hour period. The first alternateadmitted talking to his wife about the case but stated that his wife expressed no opinion. The first alternate also deniedhaving reached a decision regarding the defendant's guilt or innocence. The court then recalled the first alternate, andfive hours later, the jury returned a guilty verdict. Henderson, 45 Ill. App. 3d at 800, 359 N.E.2d at 911.

On appeal, the Henderson court first concluded that the defendant had forfeited his right to challenge the "mereirregularity" of the trial court's juror-replacement procedure by acquiescing in the court's actions. Henderson, 45 Ill. App.3d at 801-02, 359 N.E.2d at 912-13. The court further concluded that the court's replacement of the sick juror afterdeliberations had begun did not constitute plain error where the defendant failed to show that he suffered prejudice. Henderson, 45 Ill. App. 3d at 805, 359 N.E.2d at 915. In this regard, the court noted that (1) defense counsel acquiescedto the juror-replacement procedure; (2) the trial court had thoroughly examined the alternate to assure his impartialityprior to replacing the sick juror; (3) the reconstituted jury deliberated for five hours before reaching a verdict; and (4) noevidence showed that the alternate juror could not render a fair decision.

Similarly, in this case, nothing in the record indicates that defendant was prejudiced by the trial court's replacingGilpin with Lewis.
 

D. The Trial Court's Reliance on Evidence Outside the Record in Denying Defendant's Posttrial Motion

Defendant also argues that the trial court erred by relying on evidence outside the record in denying his motionfor a judgment of acquittal or a new trial. Specifically, defendant contends that the court improperly relied on Cox'stestimony from his first trial in rejecting his sufficiency-of-the-evidence claim, thus denying him due process and entitlinghim to a remand for a new hearing on his posttrial motion. We are not persuaded.

In support of his argument, defendant cites People v. Mitchell, 152 Ill. 2d 274, 323, 604 N.E.2d 877, 901 (1992),in which the supreme court concluded that the defendant's due- process rights were violated because the trial court failedto recall certain testimony in denying the defendant's motion to suppress his confession. In that case, the trial courtexpressly based its denial of the defendant's motion to suppress on its belief that the defendant never testified that he(1) believed he was not free to leave the police station or (2) was denied permission to leave police custody. Contraryto the court's understanding, the record showed that the defendant in fact testified that he believed he was not free toleave police custody. Mitchell, 152 Ill. 2d at 321-22, 604 N.E.2d at 900-01.

On appeal, the supreme court concluded that the defendant's due-process rights were violated because the trialcourt clearly failed to recall the crux of the defendant's testimony regarding the decisive issue of whether he was free toleave police custody. The supreme court reasoned that if the trial court had recalled, considered, and believed thedefendant's testimony, that testimony would have supported the defendant's claim of illegal seizure, and the trial courtthus should have suppressed his confession. Mitchell, 152 Ill. 2d at 322, 604 N.E.2d at 901. Ultimately, however, thesupreme court determined that the error was harmless in light of other evidence that supported a guilty verdict. Mitchell,152 Ill. 2d at 326, 604 N.E.2d at 903.

In this case, defendant filed a motion for a judgment of acquittal or a new trial, arguing that the State failed to(1) prove that he had intent to deliver the cocaine and (2) establish a sufficient chain of evidence for People's exhibit No.1. At an October 2002 hearing on that motion, defense counsel argued, in part, that the State failed to prove beyond areasonable doubt that defendant intended to deliver the cocaine. In that regard, defense counsel argued that the State'sevidence was "a little sparse" because "there was one officer who had been to a seminar or two who said that he hadhad training and that apparently [the] number [of individually wrapped packages] made an inference of possession with--or that the packaging was for sale or distribution."

In denying defendant's motion, the trial court commented on testimony presented by Cox at defendant's firsttrial, not his second trial, which is the subject of this appeal. The court specifically commented on Cox's testimony, inpertinent part, as follows:

"The officer who testified was a 24[-]year officer with the Danville [p]olice [d]epartment who *** since 1977when he began[,] he had been to every narcotics class that had been offered for police officers in the area thathe knew of. He had over 500 hours of training, 2 years in the metropolitan enforcement group as an undercoverofficer, several hundred of his own contact[s] of drug dealers and users on a regular basis in the street, [and]was well-familiar with the process of packaging and selling the rocks. [The cocaine] [r]ecovered [was] packagedin what were referred to as dime bags. *** So the bottom line, as he put it, was that this had been broken downfor sale ***."

The trial court here obviously erred by referring to Cox's testimony from defendant's first trial when discussingthe sufficiency of the evidence at defendant's second trial. However, unlike in Mitchell, had the court recalled andconsidered Wasson's testimony (as opposed to Cox's testimony in the first trial), we have no reason to believe that thecourt's decision on defendant's motion would have been different. In this regard, we note the following: (1) althoughWasson did not have as much experience in drug enforcement as did Cox, no one questioned his qualifications to givean opinion regarding whether the 1.8 grams of cocaine was packaged and intended for sale; and (2) Wasson opined thatbased on the amount of cocaine that defendant possessed and the manner in which the cocaine was packaged, theindividually wrapped packages were for sale, not personal use. See People v. Abdullah, 336 Ill. App. 3d 940, 947-48, 949-50, 785 N.E.2d 863, 870, 871 (2002) (in ruling on a motion for a judgment of acquittal, the court should look at all of theevidence in the light most favorable to the State, asking whether a reasonable person could fairly find the defendantguilty; in ruling on a motion for a new trial, the court should consider whether the jury's verdict was supported by theevidence). Because the court's decision would not have been different had the court corrected its error and consideredWasson's testimony, we conclude that defendant was not denied due process. We thus deny defendant's request toremand this case for a new hearing on his posttrial motion.
 

E. Sufficiency of the Evidence

The material in this section is nonpublishable under Supreme Court Rule 23 (166 Ill. 2d R. 23).
 

F. Defendant's Claim That He Received Ineffective Assistance of Trial Counsel

Last, defendant argues that he received ineffective assistance of trial counsel. Specifically, he contendsthat his counsel was ineffective in that he (1) should have filed a motion to suppress the seized cocaine and hisstatements to Cox on the ground that police lacked probable cause to arrest him in the first instance and (2) failed tocross-examine Wasson as to defendant's intent to deliver.

Ineffective-assistance-of-counsel claims are judged under the now familiar standard set forth by the UnitedStates Supreme Court in Strickland v. Washington, 466 U.S. 668, 80 L. Ed. 2d 674, 104 S. Ct. 2052 (1984). To establishineffective assistance of counsel, a defendant must first demonstrate that his defense counsel's performance wasdeficient in that "counsel made errors so serious that counsel was not functioning as the 'counsel' guaranteed thedefendant by the [s]ixth [a]mendment." Strickland, 466 U.S. at 687, 80 L. Ed. 2d at 693, 104 S. Ct. at 2064. In so doing,a defendant must overcome the strong presumption that the challenged action or inaction of counsel was theproduct of sound trial strategy and not of incompetence. Strickland, 466 U.S. at 689, 80 L. Ed. 2d at 694-95, 104 S. Ct.at 2065. Second, a defendant must demonstrate a reasonable probability that, but for defense counsel's deficientperformance, the result of the proceeding would have been different. Strickland, 466 U.S. at 694, 80 L. Ed. 2d at 698,104 S. Ct. at 2068. Both prongs of the Strickland test must be satisfied before a defendant can prevail on a claim ofineffective assistance of counsel. People v. Coleman, 183 Ill. 2d 366, 397-98, 701 N.E.2d 1063, 1079 (1998).

In People v. Kunze, 193 Ill. App. 3d 708, 726, 550 N.E.2d 284, 296 (1990), this court held that adjudication of aclaim of ineffective assistance of counsel is often better made in proceedings on a petition for postconviction relief,where a complete record can be made. In Kunze, 193 Ill. App. 3d at 725, 550 N.E.2d at 296, the ineffective-assistance-of-counsel claim turned on whether the defendant would have testified had he known in advance that the Statewould use his prior convictions to impeach him. Because nothing in the record permitted such a determination to bemade, this court declined to adjudicate the defendant's claim. Kunze, 193 Ill. App. 3d at 725-26, 550 N.E.2d at 296.

In addition, in Massaro v. United States, 538 U.S. 500, 155 L. Ed. 2d 714, 123 S. Ct. 1690 (2003), the UnitedStates Supreme Court provided a thorough analysis regarding why it is preferable that ineffective-assistance claimsbe considered on collateral review rather than on direct appeal. In that case, the Supreme Court considered the ruleof the Second Circuit Court of Appeals requiring that a defendant who is represented by new counsel on appealraise any ineffective-assistance-of-counsel claims on direct appeal if ineffectiveness was evident from the record. Massaro, 538 U.S. at ___, 155 L. Ed. 2d at 719-22, 123 S. Ct. at 1693-95. The Supreme Court rejected that rule, stating,in pertinent part, as follows:

"When an ineffective-assistance claim is brought on direct appeal, appellate counsel and the court mustproceed on a trial record not developed precisely for the object of litigating or preserving the claim and thusoften incomplete or inadequate for this purpose. Under [Strickland], a defendant claiming ineffectivecounsel must show that counsel's actions were not supported by a reasonable strategy and that the errorwas prejudicial. The evidence introduced at trial, however, will be devoted to issues of guilt or innocence,and the resulting record in many cases will not disclose the facts necessary to decide either prong of theStrickland analysis. If the alleged error is one of commission, the record may reflect the action taken bycounsel but not the reasons for it. The appellate court may have no way of knowing whether a seeminglyunusual or misguided action by counsel had a sound strategic motive or was taken because the counsel'salternatives were even worse. See [Guinan v. United States, 6 F.3d 468, 473 (7th Cir. 1993)] (Easterbrook, J.,concurring) ('No matter how odd or deficient trial counsel's performance may seem, that lawyer may havehad a reason for acting as he did ... Or it may turn out that counsel's overall performance was sufficientdespite a glaring omission ...')." Massaro, 538 U.S. at ___, 155 L. Ed. 2d at 720, 123 S. Ct. at 1694.

See People v. Holloman, 304 Ill. App. 3d 177, 186, 709 N.E.2d 969, 975 (1999) (in which this court declined to addresson direct appeal whether trial counsel's failure to file a motion to suppress evidence constituted ineffectiveassistance where the record contained nothing to review with respect to the officer's actions or the defendant'sstanding to raise fourth amendment issues).

Similarly, in this case, whether defendant suffered prejudice for his trial counsel's failure to move tosuppress evidence arising from defendant's arrest depends on the likelihood of the motion's success. However, therecord is devoid of factual findings on the issues pertinent to defendant's claim. Because the record containsnothing to review with respect to the appropriateness of the police officers' actions surrounding defendant's arrest,we decline to consider defendant's argument. In so doing, we note that the argument defendant makes is almostnever appropriate on direct appeal because absent a motion to suppress, it is highly unlikely that the State wouldgarner its resources to prove the propriety of the officers' actions. Thus, in such cases, we cannot be certain that therecord contains all of the evidence that could have been presented on the issue.

The record also contains nothing to review with respect to (1) why defense counsel chose to cross-examineWasson in the manner he did or (2) whether counsel's decision to cross-examine Wasson as he did constituted asound trial tactic or incompetence. Further, other than two questions that Wasson was asked at defendant's firsttrial--namely, (1) whether a drug user could use 1.8 grams of cocaine in less than one week; and (2) whether a personcould buy 1.8 grams of cocaine already packaged in 18 individual packages--the record does not suggest howWasson would have answered the questions that defendant claims counsel should have asked. Because theanswers to the questions pertinent to defendant's claim are currently de hors the record, we decline to consider them. Instead, defendant may pursue his claim under the Post-Conviction Hearing Act (725 ILCS 5/122-1 through 122-8(West 2002)). See People v. Cameron, 336 Ill. App. 3d 548, 552, 784 N.E.2d 438, 441 (2003) (in which this courtreaffirmed our decision in Kunze and declined to address on direct appeal whether trial counsel's failure to request acertain jury instruction constituted ineffective assistance); Neylon, 327 Ill. App. 3d at 312, 762 N.E.2d at 1138(reaffirming Kunze and declining to address on direct appeal whether trial counsel's failure to make an offer of proofconstituted ineffective assistance of counsel); In re Carmody, 274 Ill. App. 3d 46, 56, 653 N.E.2d 977, 984 (1995)(noting that the record on direct appeal of a criminal case rarely contains any explanation of the tactics of trialcounsel, and holding that, if those tactics are to be the subject of scrutiny, a record should be developed in whichthey can effectively be reviewed).

III. CONCLUSION

For the reasons stated, we affirm the trial court's judgment.

Affirmed.
