Facts

• On December 25, 2012, Joe Rivera and his group attended a party at John Griego's home, which ended in a confrontation resulting in Rivera shooting Nick Baker and John Griego, both of whom succumbed to their injuries. Following the incident, Rivera fled the scene and was later arrested. During his pre-trial incarceration, Rivera made several phone calls that were recorded and introduced at trial. Additionally, a video recording of Rivera's statement to detectives, where he admitted to discarding the gun and jersey he wore during the incident, was presented as evidence (paras 2-6).

Procedural History

• [Not applicable or not found]

Parties' Submissions

• Plaintiff-Appellee (State of New Mexico): Argued that the evidence, including a video recording of Rivera's statement obtained after invoking his Miranda rights, audio recordings of jail phone calls, expert witness testimony, and computer-generated simulation exhibits, was admissible and supported the convictions (paras 10-24).
• Defendant-Appellant (Joe Rivera): Contended that various evidentiary errors occurred, including the admission of a video recording obtained in violation of his Miranda rights, audio recordings of jail phone calls, expert witness testimony, and computer-generated simulation exhibits. Rivera also argued that the district court failed to give a jury instruction tailored to his multiple-assailant self-defense theory, necessitating reversal (para 1).

Legal Issues

• Whether the district court's admission of certain evidence constituted reversible error, including a video recording obtained after an alleged Miranda rights violation, audio recordings of jail phone calls, expert witness testimony, and computer-generated simulation exhibits (para 10).
• Whether the district court erred in not providing a jury instruction specifically tailored to the defendant's multiple-assailant self-defense theory (para 39).

Disposition

• The Court of Appeals affirmed the convictions for second-degree murder, voluntary manslaughter, tampering with evidence, and conspiracy to commit tampering with evidence (para 1).

Reasons

• JAMES J. WECHSLER, Judge (LINDA M. VANZI, Chief Judge, and JONATHAN B. SUTIN, Judge concurring): The court found that the defendant's claims of evidentiary error lacked merit. It held that the admission of the video recording of Rivera's statement did not constitute a violation of his Miranda rights or, if it did, any error was harmless given the cumulative nature of his trial testimony. The court also found no abuse of discretion in admitting the audio recordings of jail phone calls, as sufficient foundation was provided for their authenticity. The qualification of the expert witness and the reliability of his testimony, along with the computer-generated simulation exhibits, were deemed not to constitute an abuse of discretion. Regarding the jury instructions, the court concluded that the instructions given did not confuse or misdirect the jury, and Rivera had the opportunity to present his defense theory effectively. Therefore, no fundamental error occurred in failing to provide a specific multiple-assailant self-defense instruction (paras 10-42).
