This matter arises out of defendants guilty verdict of endangering the welfare of 
a child, in violation of N.J.S.A. 2C: 24-4(a), in connection with the death 
of her son MaD.  Defendant told police investigators that on June 8, 1995, 
she had left MaD with his father, Richard Patterson, while she went into 
Penns Grove for the evening.  She further told investigators that at around 11:30 
p.m. she saw Patterson in Penns Grove and confronted him as to why 
he was not with MaD.  She stated that she then tried to get 
a ride back to the motel where she was living and when she 
finally got there, at 1:30 a.m., she found that her son was not 
breathing.  She called 911 and administered CPR.  MaD was dead on arrival at 
the Salem County Memorial Hospital.  The doctor at the emergency room observed a 
bruise on MaDs face and became suspicious that there had been some type 
of child abuse.  The doctor performing the autopsy observed four injuries on MaD, 
including a bruise on the right side of the head and a larger 
bruise on the left side of the face.  That doctor testified that, in 
his opinion, MaD had been the victim of child abuse.  
    Upon questioning by investigating officers, defendant stated that Patterson had promised to stay 
with MaD.  When questioned, Patterson claimed that he had made no such promise 
and had not been with MaD that night.  In fact, Patterson claimed that 
he saw defendant three times that evening, without MaD, in Penns Grove, and 
that he had asked her where she had left MaD.  He also claimed 
to have received two phone calls from defendant that night, the first asking 
why he had left MaD, which he did not understand, and the second 
saying that MaD was dead.  Patterson provided investigators with the names of a 
number of alibi witnesses that could attest to his whereabouts the night in 
question.  These witnesses never took the stand, but the investigating officers testified that 
their statements substantiated Pattersons claims as to his whereabouts and that their statements 
were more credible than defendants.  The officers further testified that they could not 
charge Patterson with anything.   
    Defendant, who did not testify at trial, appealed her conviction and the Appellate 
Division affirmed in an unreported decision.  Defendant filed a petition for certification in 
which she challenged the admission of prejudicial hearsay evidence and the adequacy of 
the trial courts jury unanimity instruction. 
    The Supreme Court granted defendants petition for certification. 
 HELD:  The admission of the challenged testimony constituted plain error and the trial 
court should have provided the jury with a more specific unanimity charge.  The 
judgment of the Appellate Division is reversed.    
1. The admission of the challenged testimony of the investigating officers constituted plain 
error.  First, they recounted the out-of-court statements of non-testifying witnesses in contravention of 
our hearsay rules.  Second, the officers told the jury outright that those statements 
substantiated Pattersons testimony when, in fact, they had absolutely no bearing whatsoever on 
the pivotal issue of whether Patterson had promised the defendant that he would 
care for MaD.  Third, one of the investigating officers testified that Patterson was 
more credible than defendant when that was the ultimate question for the jury. 
 Based on the hearsay evidence, the police essentially gave the jury their opinion 
regarding the innocence of Patterson and inferentially the guilt of defendant.  That is 
not allowed.  (Pp. 8-15)
2.  The jury charge in the instant matter was correct as far as 
it went.  The fundamental issue is whether a more specific instruction was required 
in order to avert the possibility of a fragmented verdict.  Courts should remain 
alert to the necessity of tailoring jury instructions to the facts and of 
utilizing a specific unanimity charge in any case in which the danger of 
a fragmented verdict is even reasonably debatable.  The instant case embodies the very 
circumstances warranting a specific unanimity instruction. (Pp. 15-23)
The judgment of the Appellate Division is  REVERSED and the matter is  REMANDED 
to the Law Division for further proceedings consistent with this opinion.

SUPREME COURT OF NEW JERSEY
A-
91 September Term 2001
STATE OF NEW JERSEY,
    Plaintiff-Respondent,
        v.
MONICA L. FRISBY,
    Defendant-Appellant.
Argued October 7, 2002  Decided December 11, 2002
On certification to the Superior Court, Appellate Division.
Abby P. Schwartz, Assistant Deputy Public Defender, argued the cause for appellant (Yvonne 
Smith Segars, Public Defender, attorney).
Gerard C. Sims, Jr., Deputy Attorney General, argued the cause for respondent (Peter 
C. Harvey, Acting Attorney General of New Jersey, attorney).
    The opinion of the Court was delivered by 
LONG, J.
    Tried to a jury, Monica Frisby was found guilty of second degree endangering 
the welfare of a child, contrary to N.J.S.A. 2C:24-4(a), in connection with the 
death of her son, MaD.  She was sentenced to a custodial term of 
seven years.  Frisby appealed her conviction and the Appellate Division affirmed in an 
unreported decision.  State v. Frisby, No. A-294-99T4 (App. Div. Oct. 3, 2001).  We 
granted Frisbys petition for certification, 
171 N.J. 444 (2002), in which she challenged 
the admission of prejudicial evidence at trial along with the adequacy of the 
trial courts jury unanimity instruction.  We now reverse.
                        I
    At trial, the following evidence was adduced in the States case.  On June 
28, 1994, defendant Monica Frisby gave birth to a son, MaD.  The childs 
father was Richard Patterson.  From birth, MaD had special medical needs and the 
Division of Youth and Family Services (DYFS) intervened to assist Frisby with his 
medical care.  There were no allegations of abuse or neglect against Patterson.  However, 
because he was uncooperative with DYFS, Frisby was instructed not to leave MaD 
with him.  On June 7, 1995, the DYFS caseworker, Theresa McNellis, visited Frisby 
and MaD at the motel where they resided.  McNellis testified that she regularly 
saw Frisby at the motel over a seven-month period both on a scheduled 
and on an unscheduled basis.  Prior to that date, DYFS had no record 
of neglect or abuse by Frisby.  According to McNellis, the motel room was 
clean and the baby was properly attired.  Frisby directed McNellis attention to two 
minor scratches on the right side of the childs face and one on 
the left, which she attributed to an injury while the child was crawling. 
 Frisby already had made a pediatricians appointment to have the scratches looked at 
the following day.
With the exception of the scratches, McNellis saw no injuries whatsoever on MaDs 
head or face.  However, she acknowledged that MaD had an old finger injury 
that he had sustained when he caught his finger in a stroller and 
with respect to which he had received ongoing medical treatment.  McNellis testified that 
the child appeared otherwise to be in good health, well cared for, and 
appropriately developed for his age.
    On June 9, 1995, Detective Sergeant Bernard R. Buckley, of the Carneys Point 
Township Police Department, was involved in the investigation of MaDs death.  MaD had 
been brought into Salem County Memorial Hospital on a call from the motel. 
 The caller had indicated that the baby was unresponsive.  Upon meeting with an 
investigator from the prosecutors office, Buckley was informed that the baby was dead 
on arrival.  In observing MaDs body, Buckley noted that the baby had a 
long, narrow bruise on the . . . left cheek and temple area 
and what appeared to be ligature marks . . . around the wrist. 
. . . reflect[ing] that something had been placed on the wrist or 
was on the wrist snugly at some point.  Buckley testified that the ligature 
marks were not unusual and a prosecutors investigator, Leroy Pierce, testified that they 
were consistent with clothing that is often worn by infants. 
    The prosecutors investigator introduced Buckley to Monica Frisby.  Frisby was not a suspect 
at that time and willingly talked to Buckley.  Frisby told the detective that 
on June 8, she was in her motel room with the baby and 
Patterson, the babys father.  They all had gone out to visit friends and 
relatives and returned to the room at about 5:00 p.m.  She stated that 
she asked Patterson to watch MaD because she wanted to go into Penns 
Grove for the evening.  According to Buckley, Frisby said she left the baby 
with Patterson at about 7:00 p.m.  Frisby told Buckley that at about 11:30 
p.m. she saw Patterson in Penns Grove and confronted him as to why 
he wasnt in the room with the child.  Frisby said that as soon 
as she realized that the baby was alone, she immediately tried to get 
a ride back to the motel.  She was finally able to obtain a 
ride from a man named Tony and arrived at the motel around 1:30 
a.m.  Frisby said that, at first, she thought that the baby was asleep 
in the crib.  She then observed mucus around his nose and when she 
checked more closely, she found that he was not breathing.  She tried to 
get help from a friend in the motel, called 911, and performed CPR. 
 When questioned by Buckley about the bruises on the babys face, Frisby indicated 
that he had fallen off the bed the previous day and had hit 
himself on a bicycle.
    Frisby was taken to headquarters where she signed a consent to search her 
motel room.  The detective did not find a bicycle in the room.  However, 
Frisby indicated that she had used the bicycle to get to Penns Grove 
and left it there while she sought a ride home.  Patterson later confirmed 
the presence of the bicycle in Penns Grove.  
    Frisby was released from headquarters while the detective conducted his investigation.  At that 
point, Buckley initiated contact with Patterson regarding Frisbys claim that she had left 
MaD with him.  According to Buckley, Patterson told him  that he was not 
supposed to, nor did he, watch the baby that night.  He recounted where 
he had been during the course of the evening.  Buckley testified that he 
wanted to substantiate [Pattersons] claims that he had been at certain places at 
certain times as opposed to what Ms. Frisby had told us that he 
was supposed to be at the motel room at these times.  According to 
Buckley, after speaking to Pattersons witnesses, no charges were brought against him because 
his witnesses appeared to substantiate his claims about his whereabouts that evening.
    Patterson testified that MaD was his son and that on June 8, 1995, 
he saw Frisby and the baby coming out of a neighbors house and 
gave them a ride back to the motel.  He kissed the baby good-bye 
and left.  The following morning, Patterson was at work when the police came 
to talk to him.  It was at that point that he was told 
that the baby was dead.  He voluntarily accompanied a police sergeant to the 
police station where Buckley and Investigator Anthony Rastelli, of the Salem County Prosecutors 
Office, questioned him.  In response to their questioning, Patterson outlined all of the 
places he had been and all of the people he had seen on 
the previous night.  Among them were his sister, his brother-in-law, his nephew, his 
nephews wife, and a cousin.  Patterson indicated that he had seen Frisby on 
three occasions that night.  He saw her at about 9:00 p.m. as she 
went into a womans house in Penns Grove where she parked her bicycle 
on the curb.  He saw her again at about 10:00 p.m. on the 
street.  Patterson said he asked her where the baby was and Frisby said 
something nasty to him.  He said he then saw Frisby a third time, 
about midnight, when she asked him for a ride back to the motel. 
 Patterson knew that MaD was not with Frisby at any point that night 
and did not know who was watching him.  After Patterson got home that 
night, he said that Frisby called him twice.  The first time she called 
she said, Richie, . . . Whyd you leave?  And I said, What 
you talking about, and she just hung up the phone like that, and 
the second time she called, she said, Richie, MaDs dead, and she hung 
the phone up.  Patterson said he did not take those calls seriously.
    Investigator Rastelli also interviewed Patterson and some of the people that Patterson indicated 
that he had seen between 8:00 p.m. and 1:00 a.m. on the night 
MaD died.  According to Rastelli, after the investigation the police decided not to 
charge Patterson with endangering the welfare of the child.  Rastelli testified that was 
because [w]e didnt feel that there was enough evidence, that he was more 
credible than Ms. Frisby at that point. 
    Dr. Paul Reyes was the emergency room doctor on the night MaD died. 
 He attempted to treat MaD when he was brought into the emergency room 
but indicated that he basically was dead on arrival.  Dr. Reyes observed a 
bruise on MaDs face that caused him to become suspicious that there had 
been some type of abuse.  The doctor also testified that MaD might have 
been sick prior to his death as he was warm, indicating that he 
had had a fever.
    Dr. Paul J. Hoyer, the medical examiner/designated pathologist of Salem County, conducted the 
autopsy on MaD on June 9.  Dr. Hoyer observed four injuries on MaD: 
 a small bruise on the left side of the forehead; a larger bruise 
on the left side of the face; a bruise on the right side 
of the head above the ear; and an irregularity of a finger on 
the left hand.  Hoyer indicated that those injuries occurred at three separate times. 
 The injuries on the forehead and right side of the head were less 
than twelve hours old and the larger bruise on the left side of 
the face was approximately a day old.  The finger injury was two months 
old or more because it had completely healed.  Regarding the marks on the 
wrists and ankles, the doctor opined that they could have come from the 
sleeper or from the baby having been bound.  He could not be sure. 
 The doctor testified that, in his opinion, MaD had been the victim of 
child abuse.  Frisby did not testify and called no witnesses on her behalf.
    The State offered alternative theories against Frisby:  (1) that she actually inflicted the 
injuries on MaD or failed to supervise him adequately thus resulting in his 
injury and (2) that she abandoned him.  On the evidence, the jury convicted 
Frisby of endangering the welfare of a child.  This appeal followed.  
                        II
    We turn first to Frisbys contention that the hearsay testimony proffered by the 
State improperly struck at the heart of her defense  that she had left 
the baby in Pattersons care.  Because no objection was advanced with respect to 
that hearsay evidence at trial, it must be judged under the plain-error standard: 
 that is, whether its admission is of such a nature as to have 
been clearly capable of producing an unjust result.  R. 2:10-2; State v. Macon, 
57 N.J. 325, 335 (1971).
    Specifically, Frisby challenges the testimony of Detective Buckley and Investigator Rastelli to the 
effect that Pattersons testimony was substantiated by the witnesses who told the police 
they were with him at various locations on the night in question.  As 
indicated, Detective Buckley stated that:  We wanted to substantiate his claims that he 
had been at certain places at certain times as opposed to what Ms. 
Frisby had told us that he was supposed to be at the motel 
room at these times.
Buckley concluded that:  Because of the interviews with the persons he had mentioned. 
 It appeared to substantiate his claims about his whereabouts that evening, and there 
was no  not enough information for us to charge him with anything.  Frisby 
also challenges Investigator Rastellis testimony that after interviewing his family and friends, Patterson 
was not charged because the police didnt feel that there was enough evidence, 
that he was more credible than Ms. Frisby at that point.  In sum, 
Frisby submits that the trial was tainted by inadmissible evidence and that she 
was prejudiced by the statements bolstering Pattersons credibility.  We agree.
    The officers testimony was problematic from many perspectives.  In essence, it recounted out-of-court 
statements of non-testifying witnesses to prove the truth of the matter asserted (that 
they were with Patterson at various locations other than the motel room on 
the night of MaDs death).  That testimony contravened N.J.R.E. 802, which interdicts hearsay 
except as provided by the Rules of Evidence or other law.  
The State argues that State v. Bankston, 
63 N.J. 263 (1973), is other 
law that authorized the officers to explain why they chose to prosecute Frisby 
and not Patterson.  That is a gross overstatement of the holding of Bankston. 
 To be sure, there are circumstances in which an officer will be allowed 
to testify, based generally on hearsay evidence, to explain the course of his 
or her investigation.  State v. Roach, 
146 N.J. 208, 224-25, cert. denied, 
519 U.S. 1021, 
117 S. Ct. 540, 
136 L. Ed.2d 424 (1996).  For 
example, an officer might explain that he received information that caused him to 
approach a suspect or brought him to the scene of a crime.  Bankston, 
supra, 63 N.J. at 268.  However, when the officer becomes more specific by 
repeating what some other person told him concerning a crime by the accused, 
the testimony violates the hearsay rule and implicates defendants Sixth Amendment confrontation rights. 
 Ibid. (citations omitted).  To the extent that Detective Buckley and Investigator Rastelli stated 
that the absent witnesses substantiated Pattersons testimony, they simply used a shorthand method 
of providing the detail interdicted by the hearsay rule and in so doing, 
irresistibly implicated Frisby.  Roach, supra, 146 N.J. at 225 (citing State v. Thomas, 
168 N.J. Super. 10, 15 (App. Div. 1979)).
    Another problem with the officers testimony was overbreadth.  Pattersons alibi witnesses only shed 
light on where he actually was on the night MaD died and not 
on where he was supposed to be.  The crux of this case was 
whether Patterson promised Frisby that he would care for MaD.  She told the 
police that he did.  He told them that he did not.  The alibi 
witnesses had no information whatsoever on that pivotal issue.  Yet, the officers broadly 
concluded that they substantiated Pattersons story and made him more credible than Frisby. 
 That was incorrect as a factual matter.  The witnesses only substantiated Pattersons actual 
absence from the motel, a subject that Frisby did not contest.
    The State argues that the hearsay testimony was irrelevant to the ultimate issue 
of whether Patterson had promised Frisby that he would care for MaD, and 
that therefore any error in admitting it was harmless.  Not so.  First, the 
jurors were never alerted to the fact that the witnesses did not substantiate 
Patterson on the core issue in the case  where he was supposed to 
be.  Although the jurors might have recognized that the out-of-court witnesses could not 
possibly attest to what happened in the early evening hours between Frisby and 
Patterson at the motel, from the officers testimony the jurors could have concluded 
that those witnesses substantiated Pattersons claim that he saw Frisby three times on 
the night of MaDs death.  If they believed that, the rest of Frisbys 
story that she only saw Patterson once and immediately headed for home was 
eviscerated.
Most important, the hearsay testimony was advanced by the officers as the foundation 
for their wholly improper credibility evaluation in favor of Patterson and against Frisby. 
 Based on the hearsay evidence, the police essentially gave the jury their opinion 
regarding the innocence of Patterson and inferentially the guilt of Frisby.  That is 
not allowed. 
Indeed, in State v. Hightower, 
120 N.J. 378, 426 (1990), we specifically disapproved 
the testimony of a police officer that expressed an opinion of defendants guilt. 
 We stated that:
We go to extraordinary lengths in ordinary criminal cases to preserve the integrity 
and neutrality of jury deliberations, to avoid inadvertently encouraging a jury prematurely to 
think of a defendant as guilty, to assure the complete opportunity of the 
jury alone to determine guilt, to prevent the court or the State from 
expressing an opinion of defendants guilt, and to require the jury to determine 
under proper charges no matter how obvious guilt may be.  A failure to 
abide by and honor these strictures fatally weakens the role of the jury, 
depriving a defendant of the right to trial by jury.  
[Id. at 427-28 (citations omitted).]
See also State v. Odom, 
116 N.J. 65, 77 (1989) (holding that expert 
testimony opining on defendants guilt wholly improper because criminal guilt or innocence is 
jurys exclusive responsibility); State v. Landeros, 
20 N.J. 69, 74-75 (1955) (holding that 
police captains testimony regarding defendants guilt was so prejudicial that it warranted reversal 
of defendants conviction).
The State argues that the officers testimony regarding Pattersons credibility was not a 
commentary on guilt as interdicted by Hightower.  On the contrary, like the testimony 
ruled improper in Roach, supra, it implicated Frisby by necessary inference. 146 N.J. 
at 224.  Moreover, the mere assessment of another witnesss credibility is prohibited.  In 
State v. J.Q., the Appellate Division spoke directly to this issue in the 
context of expert opinion:
The question of whether a particular witness is testifying in a truthful manner 
is one that must be answered in reliance upon inferences drawn from the 
ordinary experiences of life and common knowledge as to the natural tendencies of 
human nature, as well as upon observations of the demeanor and character of 
the witness.  The phenomenon of lying, and situations in which prevarications might be 
expected to occur, have traditionally been regarded as within the ordinary facility of 
jurors to assess.  For this reason, the question of a witness credibility has 
routinely been regarded as a decision reserved exclusively for the jury.
It is an encroachment upon the province of the jury to permit admission 
of expert testimony on the issue of a witness credibility.
[
252 N.J. Super. 11, 39 (App. Div. 1991) (quoting Commonwealth v. Seese, 
517 A.2d 920, 922 (Pa. 1986)), affd, 
130 N.J. 554 (1993).]
As the Appellate Division concluded, credibility is an issue which is peculiarly within 
the jurys ken and with respect to which ordinarily jurors require no expert 
assistance.  Ibid.  
Likewise, in State v. Pasterick, 
285 N.J. Super. 607, 620 (App. Div. 1995), 
the Appellate Division noted:  There is no provision in our legal system for 
a truth-teller who is authorized to advise the jury on the basis of 
ex parte investigations what the facts are and that the defendants story is 
a lie.  In Pasterick, the lack of objection by defense counsel to the 
experts testimony was of no consequence. Id. at 621.  As noted by that 
court, although not objected to, we hold that it was plain error because 
it deprived defendant of his right to a fair trial. Id. at 622 
(emphasis added) (citations omitted).
    We think the admission of the challenged testimony of Detective Buckley and Investigator 
Rastelli constituted plain error.  First, they recounted the out-of-court statements of non-testifying witnesses 
in contravention of our hearsay rules.  Second, the officers told the jury outright 
that those statements substantiated Pattersons testimony when, in fact, they had absolutely no 
bearing whatsoever on the pivotal issue of whether Patterson had promised Frisby that 
he would care for MaD.  Third, officer Rastelli testified that Patterson was more 
credible than Frisby when that was the ultimate question for the jury.  The 
effect of the police testimony essentially vouching for Patterson cannot be overstated.  As 
we recently observed in Neno v. Clinton, 
167 N.J. 573, 586-87 (2001), in 
connection with a police witnesss testimony about fault for an automobile accident:
A jury may be inclined to accord special respect to such a witness. 
 Deference to a police officer in turn may have enhanced the credibility of 
the statements of Burnett and Meyer.  It is safe to say that Officer 
Kellys testimony created improper bolstering. . . . The jury heard from a 
law enforcement officer trained in accident investigation that he believed plaintiffs caused the 
accident. The jury could have ascribed almost determinative significance to that opinion, which 
went to the heart of the case.
This case was a pitched credibility battle between Frisby and Patterson on the 
pivotal issue of whether Patterson promised to care for MaD.  Any improper influence 
on the jury that could have tipped the credibility scale was necessarily harmful 
and warrants reversal.
                        III
We turn next to Frisbys claims regarding the jury instruction on unanimity.  The 
unanimity principle is deeply ingrained in our jurisprudence:
Like the reasonable doubt standard that was found to be an indispensable element 
at all criminal trials in 
In re Winship, 
397 U.S. 358, 364, 
90 S. Ct. 1068, 1072, 
25 L. Ed. 2d 368, 375 (1970), the unanimous jury requirement impresses on the 
trier of fact the necessity of reaching a subjective state of certitude on 
the facts in issue. United States v. Gipson, 
553 F.2d 453, 457 (5th 
Cir. 1977) (quoting 
In re Winship, supra, 
397 U.S. at 364, 
90 S. Ct. at 1072, 
25 L. Ed. 2d at 375). Our Constitution presupposes a requirement of a unanimous jury verdict 
in criminal cases. N.J. Const. art. I, [¶] 9.  Our Rules require that 
the verdict shall be unanimous in all criminal actions. R. 
1:8-9. 
[State v. Parker, 
124 N.J. 628, 633 (1991), cert. denied, 
503 U.S. 939, 
112 S. Ct. 1483, 
117 L. Ed.2d 625 (1992).]
The notion of unanimity requires jurors to be in substantial agreement as to 
just what a defendant did before determining his or her guilt or innocence. 
 Gipson, supra, 553 F.
2d at 457.  Requiring the vote of twelve jurors to 
convict a defendant does little to insure that his right to a unanimous 
verdict is protected unless the prerequisite of jury consensus as to the defendants 
course of action is also required.  Id. at 458 (footnote omitted).
    Although the need for juror unanimity is obvious, exactly how it plays out 
in individual cases is more complicated.  For example, it has been held that 
a jury does not have to agree unanimously on whether a defendant has 
acted as a principal or an accomplice.  United States v. Peterson, 
768 F.2d 64 (2d Cir.) (finding that jury unanimity regarding whether defendant aided or abetted 
in drug distribution crime not required for purposes of determining if defendant was 
statutory principal), cert. denied, 
474 U.S. 923, 
106 S. Ct. 257, 
88 L. 
Ed.2d 264 (1985).  It has also been held that unanimity is not 
required when a statute embodies a single offense that may be committed in 
a number of cognate ways.  United States v. UCO Oil Co., 
546 F.2d 833 (9th Cir. 1976) (determining that jury unanimity on specifics not required in 
conviction for making false statements and concealing material fact by trick, scheme, or 
device in relation to gasoline service station business), cert. denied, 
430 U.S. 966, 
97 S. Ct. 1646, 
52 L. Ed.2d 357 (1977); see generally Tim 
A. Thomas, J.D., Annotation, Requirement of Jury Unanimity as to Mode of Committing 
Crime Under Statute Setting Forth the Various Modes by Which Offense May Be 
Committed, 
75 A.L.R.4th 91 (1990).
    It is clear, however, that there are some circumstances in which a general 
unanimity charge will be inadequate.  In Parker, supra, we gave examples of such 
circumstances,  
[when] a single crime can be proven by different theories based on different 
acts and at least two of these theories rely on different evidence, and 
[when] the circumstances demonstrate a reasonable possibility that a juror will find one 
theory proven and the other not proven but that all of the jurors 
will not agree on the same theory.  People v. Melendez, 
224 Cal.App.3d 1420, 
1433-34, 
274 Cal.Rptr. 599, 608 (1990). . . . [S]ee also United States 
v. Payseno, 
782 F.2d 832, 836 (9th Cir. 1986) ([When] there is a 
genuine possibility of jury confusion or that a conviction may occur as the 
result of different jurors concluding that the defendant committed different acts, the general 
unanimity instruction does not suffice. (quoting United States v. Echeverry, 
719 F.2d 974, 
975 (9th Cir. 1983))). . . . [W]here the facts are exceptionally complex, 
see Payseno, [supra,] 782 F.
2d at 836-37, or where the allegations in a 
single count are either contradictory or only marginally related to one another, id., 
or where there is a variance between the indictment and the proof at 
trial, United States v. Echeverry,

(9th Cir. 1983), United States v. Mastelotto,

2d at 376-77.  In these instances, the trial court must give an 
augmented unanimity instruction. [United States v. Ryan, 
828 F.2d 1010, 1020 (3d Cir. 
1987).]
[124 N.J. at 635-36.]
We concluded:
Concerning the need for a specific unanimity instruction, we agree with the proposition 
stated in North I that is generally applied in the federal system: in 
cases where there is a danger of a fragmented verdict the trial court 
must upon request offer a specific unanimity instruction.  North I, supra, 910 F.2d 
at 875; accord United States v. Ryan, supra, 
828 F.2d 1010; United States 
v. Mangieri, 
694 F.2d 1270 (D.C. Cir. 1982).
[Id. at 637.]
    Because we adjudicate this claim under the plain-error standard, the issue is whether 
the failure of the trial court to give a specific unanimity instruction sua 
sponte was clearly capable of producing an unjust result.  R. 2:10-2.  This is 
not a case in which the jury charge was incorrect on its face. 
 See, e.g., State v. Robinson, 
165 N.J. 32, 40 (2000) (explaining that failure 
to provide proper jury instructions may constitute plain error).  The charge was correct 
as far as it went.  The fundamental issue is whether a more specific 
instruction was required in order to avert the possibility of a fragmented verdict. 
 We think it was.
This case embodies the very circumstances to which we adverted in Parker as 
warranting a specific unanimity instruction.  Endangering the welfare of a child, N.J.S.A. 2C:24-4(a), 
has three elements:  that the victim was a child; that defendant had a 
duty to care for him; and that defendant knowingly caused him harm, making 
him an abused or neglected child.  The State proffered two theories to undergird 
its case.  The first was that Frisby either inflicted the injury upon MaD 
or failed to supervise him, resulting in the injury.  The second was that 
she abandoned him in the motel room.
In instructing the jury on those theories, the trial court stated: 
What is in contention is the third element.  Remember that the third element 
is that [defendant] knowingly caused MaD harm that would make MaD an abused 
or neglected child.  I've just told you what knowingly is, and with regards 
to whether MaD was an abused or neglected child, the State makes two 
separate contentions, and I've read you those legal definitions, but I would suggest 
that for the first the State contends that [defendant] inflicted the injuries to 
MaDs head as described by Dr. Hoyer this morning or that she failed 
to properly supervise MaD resulting in the injuries to his head. [Defendant] denies 
inflicting any injury on MaD or failing to properly supervise him.  The second 
possible prong for the third element is where the State contends that [defendant] 
abandoned MaD on the -- in the early - I'm sorry - on 
the evening of June 8th, 1995 while she went into Penns Grove.  [Defendant] 
asserts that she did not abandon MaD and that she left him in 
the care of Richard Patterson.  For the State to meet the burden of 
proof on the third element, they must prove to you beyond a reasonable 
doubt that either of the two exists.  They do not have to prove 
both of them.  So if you're convinced beyond a reasonable doubt that the 
State has proved its contentions with regards to [defendant] inflicting injuries on MaD 
or not - or failing to supervise him so that the injuries resulted, 
that's sufficient, or if you find that [defendant] abandoned MaD on the evening 
of June 8th, 1995, or - I'm sorry - not or. If you 
find that she abandoned him, that would meet the third prong.  The State 
does not have to prove both contentions.  They're alternate co - alternate arguments 
made by the State.  Ladies and gentlemen, if you find that the State 
has proven all three elements, age, duty, and what occurred, then you must 
find the defendant - I'm sorry - proved all three elements beyond a 
reasonable doubt, then you must find the defendant guilty.  If you find that 
the State has failed to prove any of the three elements; and in 
this case, it would be the third one, either of the two alternate 
arguments, then you must find the defendant not guilty.
[(Emphasis added).]
The court also gave a general unanimity instruction later in the charge:
The verdict must represent the considered judgment of each juror and must be 
unanimous as to the charge.  This means that all of you must agree 
if the defendant is guilty or not guilty on the charge of endangering 
the welfare of a child. . . . Since this is a criminal 
case, your verdict, whatever it may be, must be unanimous.  That means that 
all 12 who ultimately are chosen as a deliberating jury must agree as 
to the verdict.
Frisby contends that the unanimity aspects of the instruction were fashioned in such 
a way as to allow a non-unanimous patchwork verdict against her.  More particularly, 
because the state proffered two entirely distinct factual scenarios to support the third 
element of the crime of endangering, Frisby contends that the jurors may have 
convicted her although some believed she was at the motel when the injuries 
were sustained while others believed she abandoned MaD for a night on the 
town.
We agree with Frisby.  Different theories were advanced based on different acts and 
entirely different evidence.  In one scenario, Frisby was present and inflicted the injuries 
on MaD or allowed him to be injured.  In the other, she went 
out and left him alone.  Those are unlike the facts deemed cognate in 
Parker, supra, where the defendant showed the child victims pornography, informed them of 
her sexual desires, and used foul language, which acts the Court held to 
be conceptually similar.  124 N.J. at 639.  Nor are they like the facts 
in State v. T.C., 
347 N.J. Super. 219 (App. Div. 2002) (petition for 
certification pending), where the Appellate Division held that different sadistic acts toward a 
child victim including hitting, verbal abuse, starvation, and humiliation did not require a 
specific unanimity charge because there was a single theory of ongoing emotional and 
physical abuse advanced and the acts alleged were conceptually similar.
    On the contrary, the allegations in this case were contradictory, conceptually distinct, and 
not even marginally related to each other, thus requiring a specific unanimity instruction. 
 Cf. Parker, supra, 124 N.J. at 639 (finding that defendants acts were conceptually 
similar thus obviating need for specific unanimity charge).  A jury verdict form could 
have clarified matters but was not used.  Courts should remain alert to the 
necessity of tailoring jury instructions to the facts and of utilizing a specific 
unanimity charge in any case in which the danger of a fragmented verdict 
is even reasonably debatable.
    We note that the State contends that because there was no evidence of 
jury confusion a reversal is not required.  That argument dices the notion of 
jury confusion referred to in our unanimity case law too finely.  To be 
sure, if a jury affirmatively evidences confusion by its questions or its answers 
on a jury verdict form, that would be an important factor in determining 
whether the absence of a specific unanimity charge caused defendant to be prejudiced. 
 But the converse does not follow.  As a result of the absence of 
a specific unanimity charge, the jurors here may have been perfectly clear that 
they could convict Frisby although they completely disagreed regarding contradictory and conceptually distinct 
theories and the evidence underlying them.  That is especially true in light of 
the courts instruction that to convict the State had to prove either of 
its theories beyond a reasonable doubt.  Such a jury would evidence no confusion 
but would nevertheless meet the confusion standard in the cases.

    The judgment of the Appellate Division is reversed.  The matter is remanded for 
retrial to take place in accordance with the principles to which we have 
adverted.
