State v. Mancia; State v. Saedt; State v. Alvarez

2026 UT App 30 · Utah Court of Appeals · March 5, 2026 · No. Opinion Nos. 20230735-CA, 20230760-CA, 20240282-CA

Summary

The Utah Court of Appeals affirmed the murder convictions of Jose Humberto Mancia, Argenis Daniel Ramirez Saedt, and Rosalio Andres Alvarez arising from a drive-by shooting and fatal vehicle collision. The defendants argued that their trial counsel were ineffective, including for failing to request a legal definition of recklessness in the accomplice-liability jury instructions. The court rejected the claims and held that the alleged errors did not prejudice the defendants.

Holdings

  1. Counsel's failure to request an instruction defining the legal meaning of recklessness did not establish ineffective assistance because the omission did not create a realistic possibility that the jury convicted defendants on impermissible factual findings, and there was no reasonable probability of a different verdict.
  2. Counsel did not perform deficiently by failing to object to instructions that combined the elements of felony discharge of a firearm and party liability, because the instructions correctly stated the law.
  3. Even assuming counsel performed deficiently by failing to object to the testimony describing the victims' character and the effect of their deaths on the victims' sister, defendants were not prejudiced because there was no reasonable likelihood of a different verdict.
  4. Counsel was not ineffective for failing to request a specific unanimity instruction because the alternative methods of committing felony discharge of a firearm and the principal-versus-accomplice theories were means of committing a single offense, not separate legal elements or distinct crimes requiring separate unanimity.
  5. Mancia's counsel was not ineffective for failing to object to his prosecution as an adult under the party-liability theory because the amended juvenile jurisdiction statute was substantive, not procedural, and did not apply retroactively to the charged conduct.
  6. The alleged errors did not cumulatively prejudice defendants because, even assuming the lack of a mens rea definition and the admission of the challenged testimony were errors with a conceivable potential for harm, their combined effect did not undermine confidence in the verdict.

Questions Presented

  1. Whether counsel was ineffective for failing to request a legal definition of recklessness in the accomplice-liability jury instructions.
  2. Whether counsel was ineffective for failing to object to the format of jury instructions combining the mens rea for felony discharge of a firearm with party liability.
  3. Whether counsel was ineffective for failing to object to testimony concerning the victims' character and the effect of their deaths on a family member.
  4. Whether counsel was ineffective for failing to request a specific unanimity instruction concerning alternative means of committing felony discharge of a firearm and party liability.
  5. Whether counsel was ineffective for failing to object to prosecution of Mancia as an adult under party liability after amendment of the juvenile jurisdiction statute.
  6. Whether the alleged errors cumulatively prejudiced the defendants.
