Background
Katrina Gabrielle Carvalho was convicted of first-degree murder with a deadly weapon after Vintell Johnson was shot outside his apartment complex. Johnson had argued with Carvalho and her sister, Regina, after dinner. A witness saw Carvalho point a gun toward Johnson, then took cover and heard shots seconds later, but did not see who fired. Another witness saw Johnson and Regina arguing and likewise heard, but did not see, the shooting. Johnson died from three gunshot wounds to the back.
Carvalho’s first trial ended in a mistrial after witnesses disclosed new evidence. At the second trial, Regina invoked the Fifth Amendment, and the State used testimony she had given at an earlier hearing. Carvalho maintained that someone else fired the shots. During closing argument, defense counsel repeatedly told the jury that evidence pointing to Carvalho also pointed to Regina. The district court sustained objections, told jurors not to speculate about Regina’s guilt, fined counsel $500, and threatened criminal contempt if counsel continued. The jury convicted Carvalho, and she received life with parole eligibility after 28 years.
The Court’s Holding
The Nevada Supreme Court reversed and ordered a new trial before a different district court department. Justice Stiglich drew a crucial line between asking jurors to decide a third party’s guilt and using evidence that a third party may have committed the crime to create reasonable doubt about the accused. The former is improper because the defendant—not the third party—is on trial. The latter is a constitutionally protected theory of defense when it rests on reasonable inferences from evidence in the record.
Carvalho’s argument stayed on the permissible side of that line. Neither eyewitness saw the shooter, Regina stood next to Carvalho, and the circumstances supported an inference that Regina could have taken the gun and fired. Counsel did not ask jurors to ignore Carvalho’s guilt or formally convict Regina. Counsel argued that the uncertainty over which sister fired prevented the State from proving Carvalho guilty beyond a reasonable doubt.
The standard jury instruction stating that jurors were not called upon to determine another person’s guilt was legally correct in isolation. But the trial court’s repeated statements went further by directing jurors not to consider Regina as the possible shooter at all. The sanction, contempt threat, and refusal to explain the boundary chilled the defense; counsel stopped mentioning Regina. Because those actions effectively removed Carvalho’s principal defense from deliberations, the error was not harmless beyond a reasonable doubt. The court rejected Carvalho’s separate speedy-trial and sufficiency challenges, meaning the State may retry her.
Key Takeaways
- A Nevada criminal defendant may argue that an identified alternative suspect committed the charged crime when evidence supports that inference and the argument is offered to establish reasonable doubt.
- The jury need not—and should not—decide whether the alternative suspect is guilty. But it may consider that possibility when determining whether the State proved the defendant’s guilt.
- A correct jury instruction can become reversible error when additional judicial comments effectively take a supported defense theory away from the jury.
- Restrictions on closing argument receive harmless-error review, and repeated admonitions, sanctions, or contempt threats can demonstrate that the restriction affected the verdict.
Why It Matters
The opinion gives Nevada trial lawyers a usable framework for alternative-suspect arguments. Defense counsel should tie each inference to admitted evidence and explicitly explain that the third party is not on trial. Prosecutors may object when argument relies on facts outside the record or invites jurors to adjudicate someone else’s criminal liability, but not merely because the defense identifies another plausible perpetrator.
Trial judges must preserve that distinction when ruling in front of jurors. A limiting instruction may accurately say the jury is deciding only the defendant’s guilt, yet the court cannot use it to exclude a supported route to reasonable doubt. The decision also shows why the tone and cumulative effect of courtroom interventions matter on appeal. Here, the fine and contempt warning did more than police wording; they silenced the central defense theory. For Nevada appellate practitioners, the case supplies strong authority when judicial limits on summation prevent counsel from presenting a complete defense.
