OPINION
By the Court, STIGLICH, J.:
Due process requires that a criminal “defendant be afforded a
meaningful opportunity to present a complete defense.” Hoagland v. State, 126
Nev. 381, 386, 240 P.3d 1043, 1047 (2010) (citation modified). Improperly
removing a theory of defense from the jury’s consideration is reversible error.
See Williams v. State, 99 Nev. 530, 531, 665 P.2d 260 (1983). Here, appellant
Katrina Carvalho was charged with murder with the use of a deadly weapon.
At trial, she presented an alternative-suspect defense, arguing that the
evidence supported that someone else committed the murder. During closing
argument, defense counsel argued several times that the evidence against
Carvalho “points equally” to Carvalho’s sister. The district court interrupted
argument, admonished and sanctioned defense counsel, and instructed the
jury that it was not to consider whether the sister was guilty. We conclude
that this was error.
Although it is improper to implore the jury to ignore the question
of a defendant’s guilt to determine the guilt or innocence of another person, the
defendant may urge the jury to consider the possibility that an alternative
suspect committed the charged crime as a means of raising reasonable doubt
as to the defendant’s guilt. The district court’s statements to defense counsel
and admonition to the jury effectively removed Carvalho’s alternative-suspect
defense theory from the jury’s consideration, violating her right to due process.
We therefore reverse the judgment of conviction and remand for a new trial
before a different department.
FACTS AND PROCEDURAL HISTORY
This case stems from an argument between Carvalho, her sister
Regina, and Regina’s boyfriend Vintell Johnson. Carvalho and Regina were
dropping Johnson off at his apartment complex after dinner when they all
began to argue with each other. Several witnesses at the complex, including
Johnson’s friend Jeremiah Tate, heard the argument. Tate testified that
Carvalho was in the driver’s seat of a vehicle, Johnson was in the passenger’s
seat, and Regina was standing outside of the passenger’s side. Tate
2
approached the trio and tried to defuse the situation; despite his efforts,
Johnson exited the vehicle and shoved Regina in the face. Carvalho then exited
the vehicle and stood close to her sister, at which point Johnson pushed her
too. Tate moved to stand between the Carvalho sisters and Johnson,
attempting to calm Johnson with his back turned to the Carvalhos. Tate
looked over his shoulder to see Carvalho pointing a gun at them. Johnson said
something to the effect of, “You going to shoot me?” Tate ran for cover behind
a parked car. Seconds later he heard gunshots, followed by a car door
slamming and a car speeding off. Johnson approached where Tate was hiding,
said, “The bitch shot me,” and collapsed. Johnson was transported to the
hospital and died less than an hour later as a result of three gunshot wounds
to the back.
The State charged Carvalho with murder with the use of a deadly
weapon for Johnson’s death. The first trial ended in a mistrial after witnesses
disclosed new evidence on the seventh day of trial. During the second trial, the
State introduced Regina’s prior testimony from a pretrial motion hearing on
the admissibility of prior bad act evidence and consciousness of guilt evidence.
This hearing preceded the first trial, and Regina testified to the events leading
up to and following Johnson’s death. Carvalho’s counsel conducted a cross-
examination consisting of four questions. When the State called Regina to
testify at the second trial, she invoked her Fifth Amendment right against self-
incrimination and refused to testify. The State also introduced Yaneth
Gonzalez’s prior testimony from the first trial. Having relocated to another
state, Gonzalez was experiencing mental health issues and was medically
unable to travel to attend the second trial.
Carvalho’s theory of defense was that someone else shot Johnson.
Throughout trial and in closing argument, defense counsel identified several
3
other suspects, including Regina, and highlighted the shortcomings of the
police investigation. Defense counsel argued several times that the evidence
incriminating Carvalho was equally inculpatory as to Regina. During closing
arguments, the district court sustained the State’s two objections to this line
of argument, admonishing counsel and instructing the jury that it was
improper to speculate about whether Regina was guilty of shooting Johnson.
The court then sua sponte interrupted counsel’s argument a third time and
sanctioned defense counsel with a $500 fine. The jury ultimately convicted
Carvalho of first-degree murder with the use of a deadly weapon. She was
sentenced to life in prison with the possibility of parole after 28 years.
Carvalho appeals.
DISCUSSION
Carvalho challenges the judgment of conviction on three main
grounds. First, Carvalho argues that the district court prevented defense
counsel from arguing an alternative-suspect defense to the jury, violating her
due process rights. Second, she argues that her speedy trial rights were
violated. Finally, she contends that there was insufficient evidence to support
her conviction. 1
The district court improperly removed Carvalho’s alternative-suspect theory of
defense from the jury’s consideration
Carvalho argues that the district court’s admonishments and
instructions to the jury “shut down” her defense and prevented counsel from
arguing that someone else shot Johnson. Although she concedes that the jury
1In light of our disposition, we need not address the other arguments
Carvalho raises. See Smith v. State, 142 Nev., Adv. Op. 26, 587 P.3d 251, 257
n.1 (2026) (declining to address appellant’s remaining arguments in light of
reversal on other grounds).
4
cannot be asked to determine whether an alternative suspect is guilty of
shooting Johnson beyond a reasonable doubt, Carvalho argues that the jury
could evaluate her guilt with reference to the possibility that someone else
pulled the trigger. The State argues that the court properly stopped Carvalho
from arguing facts not in evidence and that Carvalho was given sufficient
leeway to argue that there were alternative suspects. 2
Due process requires that a criminal “defendant be ‘afforded a
meaningful opportunity to present a complete defense.’” Hoagland, 126 Nev.
at 386, 240 P.3d at 1047 (quoting California v. Trombetta, 467 U.S. 479, 485
(1984)). Pursuant to that right, “defense attorneys must be permitted to argue
all reasonable inferences from the facts in the record.” Glover v. Eighth Jud.
Dist. Ct., 125 Nev. 691, 705, 220 P.3d 684, 694 (2009) (quoting United States v.
Hoffman, 964 F.2d 21, 24 (D.C. Cir. 1992)). Counsel may not, however, discuss
facts not in evidence. Id. at 706, 220 P.3d at 694. Although a defendant can
argue that “another committed the crime for which [the defendant] is tried,”
Dorsey v. State, 96 Nev. 951, 954, 620 P.2d 1261, 1263 (1980), the defendant
may not argue that someone else’s culpability should be considered rather than
the defendant’s, see Guy v. State, 108 Nev. 770, 778, 839 P.2d 578, 583 (1992).
The distinction is between pointing to evidence that a third party committed
the offense to raise reasonable doubt about the defendant’s guilt and asking
2Carvalho also argues that the district court erred in correcting defense
counsel’s statements of law on first-degree murder during closing argument.
After review, we conclude that the district court properly sustained the State’s
objection and corrected defense counsel’s misstatements. See Scott v. State, 92
Nev. 552, 556, 554 P.2d 735, 738 (1976) (holding that the court has authority
to stop counsel from misstating the law).
5
the jury to consider whether a third party should be found guilty instead of
evaluating the evidence against the defendant.
District courts have broad discretion to limit “the latitude allowed
counsel in closing argument” to prevent improper argument. Glover, 125 Nev.
at 704, 220 P.3d at 693. Thus, we review such limitations for an abuse of
discretion. Id. If we conclude the district court abused its discretion in
preventing defense counsel from arguing the theory of defense, we will reverse
the conviction unless “the State demonstrates, beyond a reasonable doubt, that
the error did not contribute to the verdict.” Valdez v. State, 124 Nev. 1172,
1189, 196 P.3d 465, 476 (2008).
Defense counsel began closing argument by stating that Carvalho
was innocent and the police arrested the wrong person. Counsel argued that
the State’s evidence as to Carvalho’s guilt applied equally to Regina, though
he clarified that Regina was not on trial. The State objected, and the court
admonished the jurors that they were “not to determine the guilt or innocence
or speculate about the guilt or innocence of any other person” and that it was
“improper argument to suggest that there’s another guilty party.” Defense
counsel confirmed that Regina was not on trial but asked the jurors to keep in
mind that the State’s theory of the case “appl[ied] to both” Carvalho and
Regina. The State again objected when defense counsel argued, “So the
question is, what reasonable inferences can you draw from the facts we had
that would suggest that the Carvalho sisters were acting in self-defense, either
themselves or each other?” The court sustained the objection and again
instructed the jurors “not to speculate on whether or not Regina Carvalho has
criminal liability in this case. It is appropriate to argue there is not proof
against [Carvalho]. It is inappropriate to suggest that you should consider the
6
guilt or innocence of another person.” The district court then admonished
defense counsel, “Don’t do it again. Please proceed.”
Defense counsel went on to argue that law enforcement failed to
adequately investigate other suspects, including Regina. He argued that the
chance police “arrested the correct Carvalho sister is 50, 50, because” the only
eyewitness did not see the shooter and no other evidence definitively identified
the shooter. Defense counsel again asserted that the evidence inculpating
Carvalho “points equally” to Regina. At that point, the district court
interrupted sua sponte and dismissed the jury. The district court then
sanctioned defense counsel for improper argument, ordering him to pay $500
for “fail[ing] to follow [the court’s] order for a third time” by asking the jury to
speculate about Regina’s guilt. The district court warned defense counsel, “If
you do it again, you’ll be subject to criminal contempt.” When defense counsel
asked for guidance about what he could argue regarding other suspects, the
district court responded:
So there’s a jury instruction, sir, that tells the jury
they are not to speculate on the guilt or innocence of
another person. After the stunt that you all pulled
putting Regina Carvalho into this room knowing that
she was going to say you have the wrong person and
then blowing kisses at your client to argue three times
in closing argument that the jury should speculate
that Regina Carvalho is guilty is no coincidence and
you and I both know it. You don’t need guidance. You
need to follow the rules. Follow the jury instructions.
That’s all the guidance you’ll get from me. Invite the
jury in.
The district court then instructed the jury:
Jury instruction number 20 reads as follows: You are
here to determine whether the defendant is guilty or
not guilty from the evidence in this case. You are not
called upon to determine whether any other person is
7
guilty or not guilty. So if the evidence in this case
convinces you beyond a reasonable doubt of the
defendant’s guilt, you should so find, even though you
may believe one or more persons are also guilty.
[Defense counsel] has three times asked you to
speculate as to the guilt or innocence of Regina
Carvalho. You may not do that. That [is] improper
argument.
Defense counsel argued that police failed to investigate other suspects but did
not mention Regina again.
We conclude that defense counsel permissibly argued an
alternative-suspect defense and that the district court abused its discretion in
preventing Carvalho from presenting that theory of defense. Defense counsel’s
argument consisted of reasonable inferences that someone other than
Carvalho, specifically Regina, was the shooter. Tate testified that he saw
Carvalho point a gun at him and Johnson, prompting Tate to take cover behind
a nearby car. Approximately five seconds later, he heard gunshots. Gonzalez
testified that she heard a commotion outside her apartment and looked outside
to see Johnson and Regina arguing in the parking lot. She heard Johnson say,
“Shoot me, shoot me,” and then heard two or three shots. Because neither
witness saw who shot Johnson, it is a reasonable inference that Regina,
standing next to Carvalho according to Tate, took the gun from her and pulled
the trigger.
Arguing that the evidence incriminated Regina as the shooter did
not argue facts not in evidence, nor did it improperly ask the jurors to ignore
the question of Carvalho’s guilt and instead determine Regina’s guilt. Rather,
defense counsel argued that reasonable doubt about Carvalho’s guilt was
present because the evidence supported the conclusion that Regina, instead of
Carvalho, shot Johnson.
8
While the instruction that the district court gave to the jury was
legally correct, the subsequent statement that the jury “may not” “speculate as
to the guilt or innocence of Regina Carvalho” was error. Coupled with the
district court’s other instructions that the jury may not “consider the guilt or
innocence of another person” and that “it [was] improper argument to suggest
that there’s another guilty party,” the district court directed the jury to not
even consider whether Regina might be the shooter. The court thus restricted
the jury’s review of the evidence and invaded the province of the jury in
excluding the prospect that Regina might have shot Johnson from its
determination whether Carvalho was guilty of murder beyond a reasonable
doubt. The court further emphasized its disfavor of contemplating Regina as
the shooter by distinguishing Tate and permitting defense counsel to argue
that “Tate is a possible shooter in this case.” In foreclosing Carvalho’s
opportunity to present an alternative-suspect defense with respect to Regina,
the district court abused its discretion when it limited closing argument.
We further conclude that this error likely contributed to the jury’s
verdict and thus was not harmless. The district court shut down Carvalho’s
argument three times, ultimately sanctioning defense counsel with a $500 fine
and refusing to provide defense counsel with guidance about permissible
argument. These reprimands chilled Carvalho’s argument that Regina was an
alternative suspect, evidenced by the fact that defense counsel did not mention
Regina for the rest of closing argument. Because the court’s admonishments
effectively removed Carvalho’s primary theory of defense from the jury’s
deliberation, we reverse the judgment of conviction and remand for a new trial.
Although we reverse on this ground, we address several other claims of error
and conclude that they lack merit such that Carvalho has not shown that those
grounds bar retrial.
9
Carvalho’s speedy trial rights were not violated
Carvalho argues that her speedy trial rights were violated because
of a two-year delay in bringing the case to trial. The State argues that
Carvalho cannot allege unconstitutional delay when such delay was defense-
driven. Moreover, the State argues that Carvalho cannot show that her case
was prejudiced by the delay.
The United States Supreme Court outlined a four-point balancing
test to determine whether a defendant’s constitutional speedy trial right has
been violated: “[1] whether delay before trial was uncommonly long,
[2] whether the government or the criminal defendant is more to blame for that
delay, [3] whether, in due course, the defendant asserted his right to a speedy
trial, and [4] whether he suffered prejudice as the delay’s result.” Doggett v.
United States, 505 U.S. 647, 651 (1992); see Barker v. Wingo, 407 U.S. 514, 530
(1972). The second factor “is the focal inquiry in a speedy trial challenge.”
Sunseri v. State, 137 Nev. 562, 564-65, 495 P.3d 127, 131 (2021) (citation
modified). Where delays “[a]re either attributable to [the defendant] or
intended to preserve his constitutional rights,” the second factor weighs
against finding a violation. Duckket v. State, 142 Nev., Adv. Op. 9, 583 P.3d
241, 248 (2026); Vermont v. Brillon, 556 U.S. 81, 90-91 (2009) (indicating “delay
caused by the defendant’s counsel is also charged against the defendant”
(citation modified)).
Here, two years passed between Carvalho’s arraignment and trial
resulting in conviction, which is presumptively prejudicial. See Sunseri, 137
Nev. at 564, 495 P.3d at 131 (holding that delays longer than one year are
presumptively prejudicial). Four delays contributed to the two-year period.
The first was a defense continuance request for more time to prepare. The
second reason for delay was Carvalho’s request for new counsel, which she
10
acknowledged would result in delay. The third delay was caused by a defense-
requested mistrial. Finally, the fourth delay was a result of a scheduling
conflict with the court’s calendar. Three out of the four delays are directly
attributable to Carvalho, and the fourth was a scheduling conflict, weighing
substantially against Carvalho. Moreover, these delays also show that
Carvalho acted inconsistently with her assertion of her speedy trial rights.
And, although Carvalho was prejudiced by the unavailability of two witnesses,
such prejudice does not outweigh the fact that the delays were substantially
more attributable to Carvalho. We therefore discern no constitutional speedy
trial violation.
Carvalho’s assertion that her statutory speedy trial rights were
violated under NRS 178.556(1) is equally unavailing. “If the defendant is
responsible for the delay of trial beyond the 60 day limit, he may not complain.”
Oberle v. Fogliani, 82 Nev. 428, 430, 420 P.2d 251, 252 (1966), superseded by
statute on other grounds, as stated in Clow v. Sheriff, 96 Nev. 605, 606, 614
P.2d 535, 535-36 (1980). Since Carvalho caused her delays, we determine there
was no statutory speedy trial violation.
Sufficient evidence supports the conviction
Carvalho next argues insufficient evidence supports the conviction
for first-degree murder with the use of a deadly weapon. We evaluate
sufficiency of the evidence claims by determining “whether, after viewing the
evidence in the light most favorable to the prosecution, any rational trier of
fact could have found the essential elements of the crime beyond a reasonable
doubt.” Barber v. State, 131 Nev. 1065, 1071, 363 P.3d 459, 464 (2015) (citation
modified). In making this determination, this court will not reweigh the
evidence or reconsider the credibility of the witnesses. Mason v. State, 118
Nev. 554, 559, 51 P.3d 521, 524 (2002). If the State presented insufficient
11
evidence to support a conviction, the “defendant is entitled to acquittal.”
Stephans v. State, 127 Nev. 712, 721, 262 P.3d 727, 734 (2011).
First-degree murder is defined under Nevada law as “the unlawful
killing of a human being,” NRS 200.010, which is “willful, deliberate, and
premediated,” NRS 200.030(1)(a). The legislature has explicitly recognized
firearms as deadly weapons. NRS 193.165(1). Between Tate’s testimony,
corroborated by other witnesses, and Carvalho’s flight to California after the
shooting, evidencing consciousness of guilt, we conclude that sufficient
evidence supports the conviction. Viewing the evidence in the light most
favorable to the prosecution, a rational trier of fact could find Carvalho shot
Johnson with the intent to kill and premeditated in the moments between
pointing the gun at Johnson and firing at his back three times.
Because we reverse for error in the trial process, as opposed to a
speedy trial violation or insufficiency of the evidence, we conclude that the
appropriate remedy here is remand for a new trial. Burks v. United States,
437 U.S. 1, 15 (1978).
CONCLUSION
A criminal defendant has a due process right to present their
theory of defense. Although a defendant is not permitted to redirect the jury’s
determination from whether the defendant is guilty to whether another person
is guilty, a defendant may argue an alternative-suspect defense to raise
reasonable doubt as to the defendant’s guilt. Here, Carvalho’s counsel argued
reasonable inferences that other people, including her sister Regina, could
have shot Johnson based on the evidence presented. Yet the district court shut
down that argument and explicitly instructed the jurors not to consider
whether Regina was the person who shot Johnson in evaluating Carvalho’s
guilt. This was an abuse of discretion. Because Carvalho was impermissibly
12
prevented from presenting her theory of defense during closing argument, we
reverse the judgment of conviction and remand for a new trial before a different
department. See Williams v. Second Jud. Dist. Ct., 142 Nev., Adv. Op. 5, 583
P.3d 223, 229-30 (2026) (reassigning matter to a different judge under this
court’s supervisory authority in light of serious concerns raised by the district
judge’s determinations).
