Submitted: November 5, 2025 Decided: February 3, 2026
Before SEITZ, Chief Justice; VALIHURA, TRAYNOR, LEGROW, and GRIFFITHS, Justices, constituting the Court en Banc.
Upon appeal from the Superior Court of the State of Delaware. REVERSED and REMANDED.
Kimberly A. Price, Esq. (argued), COLLINS PRICE WARNER WOLOSHIN, Wilmington, Delaware, for Appellant Yony Morales-Garcia.
Julie M. Donoghue, Esq. (argued) and Kenneth J. Nachbar, Esq., DELAWARE DEPARTMENT OF JUSTICE, Wilmington, Delaware, for Appellee State of Delaware.
GRIFFITHS, Justice: On January 22, 2022, two masked men dressed in dark clothing entered a
crowded restaurant in Sussex County, Delaware. After one of the men ripped
jewelry from around a restaurant patron’s neck, the other man shot and killed two
people. The State’s theory of the crime was that Appellant Yony Morales-Garcia
pulled the trigger to protect his brother, Emner Morales-Garcia, who confessed to
stealing the jewelry.
The Morales-Garcia brothers were scheduled to be tried separately. Emner
accepted a plea offer before trial, pleading guilty to first-degree robbery and second-
degree conspiracy. Yony proceeded to trial, and the jury deadlocked. In Yony’s
second trial, the jury convicted him of seventeen counts, including two counts of
first-degree murder. Yony appealed to this Court, raising two claims.
First, Yony claims that the State engaged in two instances of prosecutorial
misconduct during trial. The first time was when the State divulged in its opening
statement that Emner had “admitted to this crime already” and pleaded guilty to the
robbery. The second time was when the State elicited testimony from a detective
that Emner had already pleaded guilty to both robbery and conspiracy.
Yony’s second claim is an alternative argument. He contends that even if it
was proper for the State to mention Emner’s admission of guilt to the jury, it was
plain error for the court not to instruct the jury of the limited purpose for which it
could consider Emner’s guilty plea. We agree with Yony that the State’s repeated
2 references to Emner’s guilt was improper, violated his substantial rights, and
jeopardized the fairness and integrity of the trial process. We therefore reverse his
convictions and remand for a new trial.
BACKGROUND1
As we summarize the trial record, we are mindful that the record contains
conflicting narratives.
On January 22, 2022, Jose Ortiz-Perez began drinking around noon at a
restaurant on DuPont Highway in Sussex County, Delaware. Jose invited his
brother, Feliciano “Ely” Ortiz to join him at the restaurant for lunch. Two other
acquaintances joined them as well. By the time Jose left the restaurant, he had
consumed “more than 15 beers”2 and his recollection of the night was a “little bit
fuzzy.”3
By early evening, several other groups were seated in the restaurant. Seferino
“Frank” Garza and his friends were seated at a table near the restaurant’s backdoor.
Frank’s table included Armando Chilel-Lopez. At another table, a father and his son,
Andy Velasquez, sat and chatted with friends.

3 Back at his table, Jose was drunk.4 He angrily spewed profanities and argued
with patrons.5 For reasons unknown, Jose pointed at Andy and shouted – “Andy,
I’m going to [f…] you up!”6 Jose’s belligerence resulted in the owner of the
restaurant asking Jose, Ely, and their friends to leave. As Ely walked out of the
restaurant, he threatened Andy’s table. While Jose’s party stood outside the
restaurant, Honorio Velasquez walked in and sat at Andy’s table.
Outside the restaurant, Ely was ready to fight and was “looking for trouble.”7
He called Yony Morales-Garcia for “backup.”8 Ely told Yony that Andy was at the
restaurant. Ely knew that Yony and his brother, Emner Morales-Garcia, held a
grudge against Andy from a prior dispute. Yony drove to the restaurant with Emner
to meet Ely.
Before the Morales-Garcia brothers arrived, Jose’s party piled into a grey Ford
pickup truck and drove to a liquor store. Afterwards, Ely returned to the restaurant
but parked next door at a gas station. Ely claims that he did so because a friend
thought he left his car keys inside the restaurant. Yet no one in their party entered

4 the restaurant.9 Instead, they rummaged around inside the Ford until one of the men
exited from the vehicle and searched the ground briefly.10
Ely claimed that he peered through the restaurant’s entrance doors to see if the
keys were still at their table; they were not there. He then walked to a nearby
convenience store and purchased a soda.11 Before entering the store, Ely removed a
balaclava mask that he was wearing so that he did not appear suspicious. The mask
belonged to Jose and, when worn, covered Ely’s entire face except for his eyes and
eyebrows. When Ely returned to the Ford, Yony called him to say that he was almost
there. Ely then drove the Ford around to the back of the gas station and parked along
the side of a used car lot. Ely knew parking there would make the Ford more difficult
to see from the highway.12 Shortly thereafter, Yony and Emner pulled into the
restaurant’s parking lot in a black Kia sports utility vehicle.
At this point, Ely’s and the Morales-Garcia brothers’ accounts of who went
inside the restaurant diverge. According to Ely, he walked over to the Kia in the
restaurant’s parking lot. The Kia was still running. Yony sat in the front passenger
seat, and Emner sat in the backseat. Ely said that he got into the Kia’s driver’s seat,

5 shifted the vehicle into reverse, and maneuvered it to the side of the restaurant. Yony
and Emner got out of the Kia and entered the restaurant while Ely waited in the
vehicle. Ely claimed to have a view of the restaurant’s storefront and watched as
Yony and Emner entered. He did not see anyone enter behind them. He could not
see inside the restaurant or the Ford parked on the side of the used car lot. Ely claims
that he did not witness Yony holding a firearm at any point.13 Yony tells a different
story.
According to Yony, after he parked the Kia in the restaurant’s parking lot,
Emner told him to wait in the vehicle. Yony turned on the radio and listened to
music. As Emner walked towards the restaurant, Ely intercepted him in the parking
lot. Ely was apparently angry. Ely asked Emner to go into the restaurant and steal
Frank’s crucifix pendant and gold chain from around his neck. Ely wanted to steal
the items because the people at Frank’s table had disrespected him earlier that day.
Ely pointed Frank out in the restaurant.
Emner, who admitted he was “a little tipsy,” thought it was a “joke.”14 Ely
handed Emner a balaclava mask, which Emner wore as he walked into the restaurant.
Emner felt someone enter the restaurant behind him, but he did not turn around. That
person was masked and pointed a firearm at a waitress.
13 A679 (Tr. 168:10–12) (Ely Ortiz). 14 A710 (Tr. 199:2–4) (Emner Morales-Garcia).
6 Emner rushed toward Frank’s table, reached across it, and yanked a crucifix
pendant and gold chain from around Frank’s neck. Frank did not see Emner reach
across his table because he was talking with someone beside him. Frank yelled
instinctively. Armando went after Emner. Emner attempted to run back out of the
restaurant’s entrance but stumbled and fell to the floor. As he lifted himself up off
the floor, he heard a firearm discharge.
Frank screamed for everyone to drop to the floor for cover. The second
masked man was still standing at the restaurant’s entrance with the firearm. Andy
saw the man aim the firearm at Armando and then watched as Armando went limp
and fell to the ground. He then witnessed the same fatal sequence happen to
Honorio. After Emner and the gunman left the restaurant, Frank rushed over to
Armando and Honorio and yelled at the restaurant owner to call 911.
Ely’s and the Morales-Garcia brothers’ accounts of what occurred following
the shooting also differ. According to Ely, Emner and Yony returned to the Kia and
told him that there was a problem and that they needed to leave. Ely claimed that he
did not hear any gunshots or “anything that surprised [him]” while he waited, despite
sitting in the Kia right next to the restaurant.15 He claimed that the windows were
closed and that he was listening to the radio.
15 A606–07 (Tr. 95:22–96:3) (Ely Ortiz).
7 According to the Morales-Garcia brothers, Emner and Ely ran back to the
vehicle minutes after Emner had left to search for Ely. They both got into the Kia
and told Yony to “drive.”16 Emner sat in the front passenger’s seat, and Ely sat in
the backseat. Yony described Ely as “acting weird” and “paranoid.”17 No one talked.
Emner claimed that he was too scared to turn around to see if Ely was wearing, or
holding, a mask.
Delaware State Police (“DSP”) dispatched Trooper First Class Kenny Haynes.
When he arrived at the scene, Trooper Haynes assessed the condition of the shooting
victims. While Trooper Haynes tended to the wounded, Georgetown Police
Department Master Corporal Kenneth W. Rogers collected evidence. DSP Detective
Daniel Grassi eventually arrived and served as lead investigator. He secured the
scene and assigned duties to the other investigators.
In his search for evidence, Trooper Haynes found a brass cartridge casing on
the floor of the restaurant, but he did not find a firearm. The search for evidence
also included gathering video footage. There were no working cameras inside the
restaurant or outside on its premises. However, Detective Grassi was able to recover
video footage from a convenience store and liquor store located north of the
restaurant. He was also able to recover video footage from the used car lot. The
16 A769 (Tr. 258:14–19) (Yony Morales-Garcia). 17 A769 (Tr. 258:2–23) (Yony Morales-Garcia).
8 liquor store footage recorded the Ford parked in front of it before the shooting.
Detective Grassi confirmed that Jose owned the Ford. Detective Grassi also
confirmed through the convenience store footage that Ely had walked in and
purchased a drink. That footage showed Ely meeting with Jose outside as well.18
The police also interviewed the restaurant’s patrons. Patrons described the
masked man who stole Frank’s gold chain as having two shaved lines in one of his
eyebrows. They also said that the man wore a black jacket, hoodie, and black mask.
No one was able to offer a clear description of the gunman. One patron described
the gunman as having black hair, and another said he was taller than the other masked
man.
The next day, after he heard that both victims had died, Emner buried his
clothes and the gold chain in his backyard.19 Emner then messaged Ely and told him
not to tell law enforcement about his involvement in the shooting. This message
caused Ely to become concerned. He began to worry that the Morales-Garcia
brothers might frame him. To make sure the Morales-Garcia brothers did not “pin”
the deaths on him, Ely went to talk to the police.20
18 A286–87 (Tr. 83:1–84:23) (Det. Grassi); see also Convenience Video 00:35–02:22. 19 A743 (Tr. 232:16–23) (Emner Morales-Garcia). 20 A687–88 (Tr. 176:12–177:11) (Ely Ortiz).
9 Ely spoke with Detective Grassi. Based on Ely’s account of the evening,
Detective Grassi drafted an arrest warrant for Emner and Yony and arrested them.21
Detective Grassi interviewed Emner after his arrest. Emner told Detective Grassi
that he had buried a black duffle bag containing his denim jeans, Timberland boots,
and the gold chain in his backyard.22
Emner and Yony were indicted jointly on seventeen counts: two counts of
first-degree murder, seven counts of possession of a firearm during the commission
of a felony, one count of first-degree robbery, three counts of first-degree reckless
endangering, one count of aggravated menacing, one count of carrying a concealed
deadly weapon, one count of wearing a disguise during the commission of a felony,
and one count of first-degree conspiracy.23
In January 2023, the court ordered that the Morales-Garcia brothers be tried
separately.24 Emner accepted a plea offer from the State, pleading guilty to first-
degree robbery and second-degree conspiracy.25 Yony’s case proceeded to trial in
December 2023; however, the court declared a mistrial after the jury deadlocked.26

10 The State retried the case in May 2024.27 Following the presiding judge’s
introductory remarks, the second trial began with the State’s opening statement in
which the prosecutor told the jury:
And when [Emner] tripped, the defendant opened fire in the direction toward his brother to protect his brother. Emner has actually admitted to this crime already and has pled guilty to the robbery of that chain. He also told Detective Grassi where to find the chain and some of the items of clothing that he was wearing that night. . . . [Emner] walked up to Frank and ripped the chain, as I said, and as he tripped his brother, the defendant, was nervous that the guys that he just stole from were going to attack him, so he opened fire.28
The prosecutor made these statements even though the State did not intend to call
Emner as a witness during its case-in-chief. The State also did not know whether
Emner would testify at all because it had not received a defense witness list.29
Additionally, during the State’s case-in-chief and before Emner testified, the
prosecutor elicited the following testimony from Detective Grassi:
State: And did you have another opportunity to actually speak with Emner after that night? Grassi: Yes, on January 30th.

No. 83). 28 A210 (Tr. 7:11–23) (emphasis added). 29 Oral Arg. 27:41–54 (July 9, 2025), available at https://courts.delaware.gov/supreme/oralarguments/ [hereinafter “July Oral Arg.”] (State conceded at oral argument that it did not receive a witness list from the defense). The State did receive a defense witness list for the first trial. A91 (Final Case Rev. Tr. 14:1–7) (prosecutor informing the court that she had received a copy of the defense witness list for the first trial).
11 State: Okay. And has Emner Morales Garcia resolved his charges in this case? Grassi: Yes. State: Are you aware of what the result of those -- of that was? Grassi: He pled guilty with the lead charge being robbery first. ... State: You indicated Mr. Emner Morales Garcia pled to the lead charge of robbery first degree. Are you aware if he pled to any additional charges? Grassi: He did plead to another charge. I just don't have it in front of me. I don’t know what the additional charge was. State: And -- Grassi: I believe – I’m sorry. I believe it was conspiracy, but again, I don’t have the sheet in front of me. State: Okay. Thank you.30
The prosecutor elicited testimony from Detective Grassi that Emner pleaded
guilty to “conspiracy” in addition to first-degree robbery. The prosecutor had not
mentioned the conspiracy guilty plea in her opening statement.
After Detective Grassi’s testimony, Yony’s case-in-chief began, and defense
counsel called Emner to the stand.31 During Emner’s direct examination, he implied
that Ely was the shooter because “Ely was the only other person I spoke to before I
went into the restaurant [].”32

12 During Emner’s cross-examination, the following (abridged) exchange
occurred:
State: You were ultimately arrested on criminal charges, correct? Emner: Yes. State: And you pled guilty to robbery for stealing Mr. Garza’s necklace, correct? Emner: I wasn’t going to take a plea. You guys had offered manslaughter, robbery, and conspiracy plea. My lawyer came back and he told me that you guys had offered that and that was your last offer. And I told him: Well, you know, I want to go to trial and at least prove my innocence on the part that those two individuals that were shot I had nothing to do with that. ... State: The question was: You pled guilty to robbery, correct? ... Emner: Yes, I took the plea because after my lawyer came back with the plea that you guys had offered -- the manslaughter plea -- I told him no. I didn’t want to take no plea. I wanted to go to trial. And a couple weeks before the trial, he came back and he told me that you guys offered another plea, which was robbery, and he told me that there was no point in going to trial because, at the end of the trial even if I prove my innocence on the murder charge, I was still going to have to do the time for the robbery charge because I confessed into [sic] taking the chain. So, yes, I did take the robbery charge for that reason. State: It was that robbery that you pled to that led to a double murder, correct? Emner: Yes. State: You also pled guilty to conspiracy in the second degree, correct? Emner: Yes.
13 State: Conspiracy is agreeing to commit a crime with someone else, correct? Emner: Well if that’s what you call the conversation -- yes, if that’s what you call the conversation that me and Ely had, then, yes.33
Following Emner’s testimony, Yony took the stand. Yony denied that he was
the gunman.34 He also confirmed that Emner pleaded guilty to robbery for stealing
Frank’s gold chain.35 The jury convicted Yony on all seventeen counts, including
two counts of first-degree murder.36
Yony appealed to this Court, raising two claims. He first argues that the
prosecutor committed two instances of prosecutorial misconduct that substantially
prejudiced his right to a fair trial.37 The first instance was the prosecutor’s remarks
in her opening statement that Emner had pleaded guilty to robbery and “admitted to
this crime already,” both of which she placed between statements claiming that Yony
was the shooter. The second instance was during the State’s case-in-chief – before
Emner testified – when the prosecutor elicited testimony from Detective Grassi that
Emner had pleaded guilty to first-degree robbery and “conspiracy.” Yony’s second
contention is that, even if the prosecutor’s conduct during trial was proper, it was
33 A756–58 (Tr. 245:3–247:22) (Emner Morales-Garcia). 34 A773 (Tr. 262:9–21) (Yony Morales-Garcia). 35 A774 (263:2–4) (Yony Morales-Garcia). 36 A944–47 (Completed Jury Verdict Sheet). 37 Opening Br. 38 (Feb. 28, 2025) [hereinafter “Opening Br.”].
14 plain error for the court not to give a limiting instruction sua sponte. Yony argues
that the instruction would have lessened the resulting prejudice by advising the jury
of the limited purpose for which it could consider Emner’s guilty plea.
The State counters Yony’s appeal with four arguments. First, the State argues
that Yony forfeited his right to claim prosecutorial misconduct by not objecting to
the State’s opening statement or Detective Grassi’s testimony about Emner’s guilty
plea.38 The State also argues that Yony waived his right to claim misconduct when
his trial counsel made a tactical decision not to object to hearsay testimony given by
Detective Grassi.39 Second, the State argues that the references to Emner’s guilty
plea did not constitute prosecutorial misconduct because the references were not
used as substantive evidence to prove Yony was the shooter.40
The State’s third argument is that, even if prosecutorial misconduct occurred,
reversal is unwarranted because the State introduced “overwhelming evidence” of
Yony’s guilt.41 The State’s fourth and final argument is that the Superior Court’s
failure to issue a limiting instruction to the jury did not constitute plain error because
Yony was not prejudiced by the error.42

In July 2025, this Court requested supplemental briefing. See Supr. Ct. Letter to counsel dated July 14, 2025. Both parties submitted timely supplemental briefs. In its
15 STANDARD OF REVIEW
Whether we review a claim of prosecutorial misconduct for plain error or
harmless error depends on whether the defendant fairly raised the issue below.43
Yony did not raise the issue below, so we review for plain error. Recently, in Suber
v. State, we restated the plain error standard of review. There, we posed four
questions that have traditionally formed the plain error standard.44 We start with two
threshold questions.45 The first question is whether an adequate record exists for this
Court to review the issue on appeal.46 The second question is whether “there [was]
an error.”47 That is, we ask whether the party “knowingly and intelligently waived”
supplemental brief, the State departed from its argument that the defense calling Emner alleviated any prejudice. See Defendant’s Suppl. Br. 7 (Aug. 15, 2025), and State’s Suppl. Br. 5 (Aug. 15, 2025) [hereinafter “State’s Suppl. Br.”] (agreeing that Allen should apply regardless of whether the State or defense calls the co-defendant). Following the supplemental briefing, this Court held a second oral argument on this appeal in November 2025. At the second oral argument, the State conceded that we should vacate Yony’s conviction for first-degree conspiracy. Oral Arg. 22:30–38 (Nov. 5, 2025), available at https://courts.delaware.gov/supreme/oralarguments/ [hereinafter “Nov. Oral Arg.”]; see also A944–47 (Completed Jury Verdict Sheet). The State made this concession because: (1) the jury was not instructed on an element of first-degree conspiracy, and (2) the indictment’s seventeenth count, which charged Yony with first-degree conspiracy, was a mistake and should have been second-degree conspiracy. Nov. Oral Arg. 20:05–22, 22:13–38; see also A944–47 (Completed Jury Verdict Sheet). Nevertheless, the State remained resolute at oral argument that the prosecutor did not commit misconduct or violate Allen and, even if the prosecutor did, her conduct did not constitute plain error. 43 Baker v. State, 906 A.2d 139, 148 (Del. 2006). 44 Suber v. State, __A.3d__, 2026 WL 184867, at *5 (Del. Jan. 15, 2026). 45 Id. 46 Id. 47 Id.
16 the right.48 The State carries the burden of proving waiver and we make “every
reasonable presumption against waiver.”49
If an adequate record exists and the party did not waive the right, we then
proceed to Suber’s third question for forfeited errors, which asks whether the error
was plain.50 An error is plain if it violates “current law.”51 The state of the current
law is determined from the appellate court’s point of view when reviewing the trial
record, not from the trial court’s perspective.52
If we find that the error was plain, we proceed to Suber’s fourth, and final,
question. That question is “whether the error adversely affect[ed] the substantial
rights of the party.”53 “To affect the substantial rights of a party, the error must ‘be
so clearly prejudicial as to jeopardize the fairness and integrity of the trial
process.’”54 An error is clearly prejudicial when there is a “reasonable probability
48 Id. 49 Id. (quoting Flamer v. State, 490 A.2d 104, 113 (Del. 1983)). 50 Id. at *5 & n.27 (“Waiver is often used to describe forfeiture, but the two are distinct concepts. . . . [W]aiver is the knowing and intelligent waiver of a right. Forfeiture, on the other hand, ‘is the failure to make the timely assertion of a right.’ Waived issues are not reviewed for plain error. A forfeited error can lead to reversal but is subject to plain-error review.” (citation omitted) (quoting Purnell v. State, 254 A.3d 1053, 1101 (Del. 2021))). 51 Id. at *5. 52 Id. 53 Id. at *6. 54 Id. (quoting Johnson v. State, 813 A.2d 161, 165 (Del. 2001)).
17 that, but for the error, the outcome of the proceeding would have been different.”55
The defendant bears the burden of proving prejudice under this question.56 When
the error involves jurisdiction or is otherwise a structural constitutional error, we
presume this fourth question is satisfied.57
ANALYSIS
We apply the Suber questions in turn, determining whether: (a) the trial record
is adequate; (b) the claims were forfeited or waived; (c) the claimed misconduct
violates current law; and (d) there is a reasonable probability that, but for the
misconduct, the outcome would have been different.58
A. Adequacy of the Record
The trial record is adequate to review Yony’s claims. Both instances of alleged
misconduct are contained in the trial transcript. And, unlike Swanson v. State, the
State was not precluded from creating an evidentiary record in the trial court.59 In
Swanson, this Court declined to review a defendant’s argument on appeal that the
55 Id. (quoting Greer v. United States, 593 U.S. 503, 507–08 (2021)) (internal quotation marks omitted). 56 Id. If we find that the misconduct does not warrant reversal under Suber, we proceed to a Hunter v. State analysis. In Hunter, we held that a prosecutor’s repeated “improper comments,” which we had prohibited in past decisions, required reversal. Hunter v. State, 815 A.2d 730, 738 (Del. 2002). The repetitive misconduct must be the “same errors over multiple trials.” Saavedra v. State, 225 A.3d 364, 383 (Del. 2020). Yony conceded at oral argument that Hunter does not apply here. July Oral Arg. 17:49–18:39. 57 Suber, 2026 WL 184867, at *6 & n.32. 58 Id. at *5–6. 59 Id. at *5 (quoting Swanson v. State, __A.3d__, 2025 WL 3778943, at *2 (Del. Dec. 31, 2025)).
18 search of his person violated the Fourth Amendment, as he did not move to suppress
the evidence before the trial court.60 There, we warned that it was fundamentally
unfair for Swanson to argue for the first time on appeal that the State had insufficient
evidence to search him when the State would have introduced evidence to counter
the argument at a suppression hearing.61 Here, the State was not disadvantaged by
the lack of a record.
B. Waiver of Claims
Yony did not waive his right to claim prosecutorial misconduct. The State
attempts to cast Yony’s failure to object as a tactical decision to avoid emphasizing
Emner’s guilty plea.62 The record does not support the State’s assumption as to
Yony’s trial strategy. Due to this lack of support, the State attempts to draw a
comparison to a different, express tactical decision made by defense counsel at
trial.63 Following Detective Grassi’s hearsay testimony, defense counsel spoke at
sidebar with the court:
Court: [Defense counsel], I want to direct this to you. There’s been some hearsay that’s been elicited about what Emner Morales-Garcia said. I assume that your failure to object is a tactical decision.
60 Swanson v. State, __A.3d__, 2025 WL 3778943, at *2 (Del. Dec. 31, 2025). 61 Id. at *3. 62 Answering Br. 20. 63 Id. at 18–21.
19 Defense: I have him listed as a witness. I plan on calling him as a witness. Court: All right. Very good.64
Counsel’s apparent agreement that he made a tactical decision not to object
concerned Emner’s statement about where he had hidden the duffle bag and had no
relation to the prosecutor’s opening remarks or the testimony elicited about Emner’s
guilty plea. As Yony correctly notes, defense counsel’s “tactical decision not to
object to a certain portion of testimony does not mean that he made a tactical decision
not to object to other portions of it.”65 Because Yony did not waive his claims, we
consider the error forfeited—he failed to make a timely assertion of his right—and
we proceed to Suber’s third question and consider whether the error was plain.66
C. Prosecutorial Misconduct
We find that the prosecutor’s remarks during the State’s opening statement
and her eliciting testimony about Emner’s guilty plea are both plain errors under
Allen v. State. In Allen, the defendant and his co-defendants, Isaiah Howard and
Kevin McCray, were indicted on twenty charges arising from three different
burglaries.67 Before trial, Howard and McCray pleaded guilty to lesser charges.68

20 At trial, Howard testified for the prosecution about his plea agreement.69 McCray
did not testify.70 Following Howard’s testimony, the prosecutor did not introduce
Howard’s written plea agreement into evidence.71 Instead, the prosecutor moved to
introduce McCray’s plea agreement.72 The defendant objected and argued that the
State was using McCray’s guilty plea agreement to improperly bolster Howard’s
testimony.73
This Court held in Allen that a co-defendant’s written plea agreement—like a
co-defendant’s conviction—is not generally admissible in a defendant’s trial.74
Specifically, we held that a “co-defendant’s plea agreement may not be used as
substantive evidence of a defendant’s guilt, to bolster the testimony of a co-
defendant, or to directly or indirectly vouch for the veracity of another co-defendant
who pled guilty and then testified against his or her fellow accused.”75 We permitted
a co-defendant’s guilty plea to be introduced into evidence for three limited
purposes: “allowing the jury to accurately assess the credibility of the co-defendant
witness, to address the jury’s possible concern of selective prosecution[,] or to
69 Id. 70 Id. 71 Id. 72 Id. 73 Id. 74 Id. at 450. 75 Id.
21 explain how the co-defendant witness has first-hand knowledge of the events about
which he or she is testifying.”76 The foundational principle underlying Allen is the
right of every defendant to stand or fall with the proof of the charge made against him, not against somebody else. The defendant has a right to have his guilt or innocence determined by the evidence presented against him, not by what has happened with regard to a criminal prosecution against someone else.77
Although this matter does not concern the introduction of a written plea agreement
into evidence, the same foundational principle applies. The State’s verbal reference
to a co-defendant’s guilty plea introduces the same prejudicial information to the
jury that, as in Allen, risks the jury convicting a defendant based on a co-defendant’s
admission of guilt rather than on the evidence of the defendant’s guilt.
The prosecutor’s intentional admission of inadmissible evidence violated
prosecutorial standards.78 When assessing the propriety of a prosecutor’s trial
tactics, we have been guided by American Bar Association standards.79 We
previously adopted a portion of Standard 3–6.6 (“Presentation of Evidence”), which

State, 315 A.3d 475, 489 (Del. 2024) (characterizing the prosecutorial standards and our precedent as “guideposts”).
22 precludes a prosecutor from highlighting inadmissible matters for the fact finder.80
We now adopt a relevant portion of Standard 3–6.5 (“Opening Statement at Trial”),
which restricts what the State may reference in its opening statement.81
We address each instance of misconduct separately below.
1. The Opening Statement
We hold that the State’s remarks in its opening statement amounted to
prosecutorial misconduct.82 The State knew, or should have known, that it was
impermissible to inform the jury that Emner “admitted to this crime already and has
pled guilty to the robbery of that chain” between two statements that Yony fired a
firearm to protect Emner.83 Indeed, at oral argument in this Court, the State
80 Watson, 303 A.3d at 44–45 (“The prosecutor should not bring to the attention of the trier of fact matters that the prosecutor knows to be inadmissible, whether by offering or displaying inadmissible evidence, asking legally objectionable questions, or making impermissible comments or arguments. . . .” (citation omitted)). 81 Crim. Justice Standards for the Prosecution Function Standard 3–6.5(b), Am. Bar Ass’n (2017), available at https://www.americanbar.org/groups/criminal_justice/standards/ProsecutionFunctionFourthEditi on/ [hereinafter “Standard”] (“The prosecutor’s opening statement at trial should be confined to a fair statement of the case from the prosecutor’s perspective, and discussion of evidence that the prosecutor reasonably believes will be available, offered and admitted to support the prosecution case. The prosecutor’s opening should avoid speculating about what defenses might be raised by the defense unless the prosecutor knows they will be raised.”). 82 Because prosecutorial misconduct can occur absent intent or malice, this finding is not meant as a statement on the prosecutor’s culpability. See, e.g., Trala v. State, 244 A.3d 989, 1000 (Del. 2020) (“The prosecutor has a duty to take care that the argument the State presents to the jury stands or falls on its own merit, rather than relying, even unintentionally, on the respect and deference to which the public gives the prosecutor’s office.” (emphasis added)); Flemming v. Warden, 2012 WL 3693859, at *33 (E.D. Cal. Aug. 24, 2012) (“Prosecutorial misconduct does not require a showing of bad faith or wrongful intent.”). 83 A210 (Tr. 7:11–23) (emphasis added).
23 acknowledged that these remarks were an “unfortunate decision” that “should not
have happened.”84 The remarks violated our decision in Allen v. State, as well as
prosecutorial standards.85
In our view, the prosecutor’s reference to Emner’s guilty plea in her opening
statement served to suggest that the jury infer that Yony was guilty because Emner
was guilty. As in Allen, we therefore “have no basis to conclude” that the jury did
not use Emner’s guilty plea as substantive evidence of Yony’s guilt.86
The State argues that this Court has previously held that a prosecutor’s
“negligible reference” to a co-defendant’s case outcome was not prosecutorial
misconduct.87 This is true. However, the cases cited by the State, Dillard v. State
and Wheatley v. State, are both factually distinguishable. In Dillard, the prosecutor
told the jury: “You saw and heard some things about other defendants. Those other
defendants have resolved their cases. The case today is only about Mr. Dillard and
his actions during this case and how he is involved.”88 In Wheatley, the prosecutor
informed the jury “that the defendant had an altercation with a co-defendant tried
84 July Oral Arg. 21:20–40. 85 Allen, 878 A.2d at 450. 86 Id. at 451. 87 State’s Suppl. Br. 18. 88 Dillard v. State, 337 A.3d 1267, 2024 WL 5165709, at *3 (Del. Dec. 19, 2024) (TABLE).
24 separately.”89 These statements do not explicitly refer to a co-defendant’s guilty plea
or implicate any underlying facts. Here, the prosecutor not only stated that Emner
pleaded guilty to a specific crime but also claimed that Emner “admitted to this
crime” amidst two statements asserting that Yony was the shooter and was acting to
protect Emner. These tactics created an additional inference of guilt by association
that is not present in the more general statements found in Dillard and Wheatley.
The prosecutor’s remarks in the State’s opening statement violated
prosecutorial standards.90 The remarks were impermissible because they violated
Standard 3–6.5(b).91 Under this standard, the State cannot refer to evidence in its
opening statement unless it “reasonably believes” the evidence will be “available,
offered, or admitted to support” its case.92 The State could not have reasonably
believed that the evidence would support its remarks because the State did not intend
to call Emner as a witness. In its answering brief, the State argues that the prosecutor
knew that the defense “would call him as a witness.”93 But, as the State conceded at
oral argument, the prosecutor had not received a defense witness list before trial.94
89 Wheatley v. State, 465 A.2d 1110, 1113 (Del. 1983). 90 Allen, 878 A.2d at 450. 91 Standard 3–6.5(b). 92 Id. 93 Answering Br. 23. 94 Compare Id. (arguing that the prosecutor knew the defense would call Emner to testify), with July Oral Arg. 27:41–54 (conceding at oral argument that it did not receive a witness list from the defense).
25 The State was merely speculating about Yony’s defense strategy instead of
attempting to “avoid speculating about what defenses might be raised by the
defense.”95 Although Emner testified at Yony’s first trial, Yony had the right to alter,
or even abandon, the strategy deployed in his first trial. Yony could call different
witnesses or choose not to call any witnesses. In other words, as the State conceded
at oral argument, the prosecutor did not “know” Emner would testify when she made
these remarks.96
2. Testimony Concerning Emner’s Guilt
In the State’s case-in-chief – before Emner testified – the prosecutor re-called
Detective Grassi to the stand, and he testified that Emner pleaded guilty to first-
degree robbery and “conspiracy.”97 Eliciting this testimony was impermissible
because it violated Allen, as well as prosecutorial standards.
We again see no purpose for eliciting such testimony except as substantive
evidence of Yony’s guilt.98 The State claims that Detective Grassi’s testimony was
elicited to
impeach [Emner’s] claim during direct testimony that he did not conspire with anyone, and [] to show (in conjunction with Ely Oritz Perez’s testimony as well [as] other witnesses’ testimony who were in
95 Standard 3–6.5(b). 96 Id.; July Oral Arg. 27:28–55. 97 A696, A698 (Tr. 185:3–12, 187:3–13) (Det. Grassi). 98 Allen, 878 A.2d at 450.
26 the restaurant) that Emner Morales-Garcia planned the robbery with another person and that the most likely person with whom Emner would have conspired to commit the robbery and murders was his brother, Yony Morales-Garcia.99
Both arguments fail. The first argument is based on Allen’s limited purpose
exception of “allowing the jury to accurately assess the credibility of the co-
defendant witness.”100 However, Detective Grassi testified that Emner pleaded
guilty to robbery and conspiracy before Emner testified.101 The State cannot
impeach Emner’s testimony before it has occurred.102 In the second argument, the
State concedes that it used Detective Grassi’s testimony to show that Yony conspired
with Emner not only to commit the robbery, but also the murders.103 The State
therefore used a co-defendant’s guilty plea as substantive evidence of a defendant’s
guilt.104 This was not permissible.
99 State’s Suppl. Br. 9 (emphasis added). 100 Allen, 878 A.2d at 450–51. 101 Compare A692 (Tr. 181:11) (Det. Grassi), with A706 (Tr. 195:17) (Emner Morales-Garcia). 102 See Getz v. State, 538 A.2d 726, 731–32 (Del. 1988) (“[T]he State presented the other sexual misconduct evidence in its case-in-chief and must justify its use at that time and not on the basis of whether the defendant might later offer evidence of his own character.” (emphasis added)). 103 State’s Suppl. Br. 9 (“The State used Emner Morales-Garcia’s conspiracy guilty plea . . . to show (in conjunction with Ely Oritz Perez’s testimony as well [as] other witnesses’ testimony who were in the restaurant) that Emner Morales-Garcia planned the robbery with another person and that the most likely person with whom Emner would have conspired to commit the robbery and murders was his brother, Yony Morales-Garcia.”). 104 Allen, 878 A.2d at 451.
27 At oral argument before this Court, the State asserted that it was permissible,
under Allen, for the prosecution to use the “facts underlying the guilty plea to show
that it was Yony Morales-Garcia who was in fact the other person who went into the
restaurant and committed the crimes.”105 There is one major flaw in this argument.
The facts underlying Emner’s guilty plea to first-degree robbery and second-degree
conspiracy are that Emner stole Frank’s gold chain and conspired with another
person to commit robbery. The underlying facts do not implicate Yony as the
gunman. The State repeatedly asserted at oral argument, without further
explanation, that the prosecutor’s reliance on the underlying facts of Emner’s guilty
plea was “different” from using that guilty plea as evidence of Yony’s guilt.106 Under
these circumstances, we are not persuaded that there is a difference.
Moreover, eliciting Detective Grassi’s testimony violated prosecutorial
standards. The State’s conduct violated Standard 3–6.6(d), which prevents a
prosecutor from “bring[ing] to the attention of the trier of fact matters that the
prosecutor knows to be inadmissible.”107 The State knew, or should have known,
that eliciting such testimony from Detective Grassi before Emner testified was
inadmissible. The prosecutor’s decision to elicit this testimony before cross-
105 See July Oral Arg. 25:18–31. 106 See July Oral Arg. 25:30–27:00. 107 Standard 3–6.6(d); see also Watson, 303 A.3d at 44.
28 examining Emner shows that the prosecutor was not introducing this fact for a proper
purpose under Allen. That is, instead of impeaching Emner when he testified, the
prosecutor chose to introduce testimony to imply Yony’s guilt.
D. Reasonable Probability of a Different Outcome
Having found that plain error occurred—in the form of prosecutorial
misconduct—our last step is to determine whether there is a reasonable probability
that, but for this misconduct, the jury’s verdict would have been different.
Regardless of whether we view the instances of misconduct separately or together,
we hold that there was a reasonable probability of a different verdict.
The central issue of this case was the gunman’s identity. As we noted in Suber,
we do not approach “violations lightly when the State relies on the improperly
admitted evidence to identify the perpetrator of a murder.”108 Contrary to the State’s
claim that the evidence of Yony’s guilt was “overwhelming,” an assertion the State
retreated from at oral argument, Yony’s first trial ended in a deadlocked jury.109 Law
enforcement found no direct evidence linking Yony to the shooting. There were no
eyewitness accounts identifying Yony, no firearm was found that was linked to Yony,
108 Suber, 2026 WL 184867, at *7. See July Oral Arg. 33:50–34:54 (when asked by the Court to clarify how the evidence against 109
Yony was “overwhelming,” the State withdrew the assertion and apologized”); Answering Br. 24; A9–10 (Super. Ct. Dkt. No. 63 (“Mistrial due to hung jury.”)).
29 and Yony’s hands (and Emner’s hands) were not tested for gunshot residue.110 And
even Ely testified that he did not see Yony with a firearm.111
The trial’s outcome rested almost entirely on whether the jury believed Ely or
Emner. It was a close question. Sufficient cumulative evidence existed in the record
for a jury to believe Emner’s narrative. Either instance of misconduct could have
carried decisive weight with a juror and improperly influenced deliberations.
Further, when the instances of misconduct are viewed collectively, the effect
of both instances clearly prejudiced Yony’s substantial rights because the
prosecutor’s remarks in her opening statement compounded the effect of Detective
Grassi’s testimony about Emner’s guilty plea. Yony has therefore met his burden of
showing that there is a reasonable probability that the outcome of his trial would
have been different if the misconduct had not occurred.112
110 A288, A294–99 (Tr. 85:10–18, 91:14–96:21) (Det. Grassi). 111 A679 (Tr. 168:10–12) (Yony Morales-Garcia). A firearm matching the brass cartridge was found nearly a month after the shooting, during a routine traffic stop, in the pocket of an individual who had no connection to the restaurant, Yony, Emner, Jose, or Ely. A294–99 (Tr. 91:14–96:21) (Det. Grassi). 112 Because Yony’s first argument is dispositive of this appeal, we do not address his second, alternative argument, which requires this Court find that the evidence of Emner’s plea was admitted for a proper, limited purpose under Allen. Purnell v. State, 106 A.3d 337, 350–51 (Del. 2014) (quoting Allen, 878 A.2d at 451). For the same reason, we do not consider the State’s waiver argument that it raised for the first time at oral argument. Specifically, the State asserted that Yony waived this alternative argument by not agreeing to include an inapplicable jury instruction in the court’s charge. See July Oral Arg. 34:55–37:25; accord State’s Suppl. Br. 6–8. To the extent the State intended this waiver argument to apply to Yony’s claims of prosecutorial misconduct, its argument lacks adequate development and therefore is deemed waived.
30 CONCLUSION
For these reasons, we REVERSE Yony Morales-Garcia’s convictions and
REMAND for a new trial.
