Facts

• The Defendant, Anthony Blas Yepez, was convicted of second-degree murder, tampering with evidence, and unlawful taking of a motor vehicle following an incident where George Ortiz, the victim, was killed. The Defendant and his girlfriend, Jeannie “Anna” Sandoval, who was raised by Ortiz, were living with the victim. On the day of the incident, after consuming alcohol, an argument escalated between Sandoval and Ortiz, leading to a physical altercation between the Defendant and Ortiz. The Defendant restrained Ortiz, leading to Ortiz's death, followed by the Defendant and Sandoval attempting to destroy evidence by setting Ortiz's body on fire and fleeing in Ortiz's car (paras 2-5).

Procedural History

• [Not applicable or not found]

Parties' Submissions

• Defendant-Appellant: Argued that the district court improperly excluded expert opinion testimony regarding his ability to form deliberate intent, which was crucial for his defense against the charge of second-degree murder (para 1).
• Plaintiff-Appellee (State of New Mexico): Contended that the proposed expert testimony did not meet the reliability and relevance standards required for admissibility. The State argued that there was no direct link between the low-activity MAOA variant and increased violent behavior, and that the Defendant's proposed evidence was too complicated and would likely confuse the jury (para 8).

Legal Issues

• Whether the district court erred in excluding expert testimony related to the Defendant's ability to form deliberate intent (para 1).
• Whether the exclusion of the expert testimony was harmless in light of the jury's verdict (para 32).

Disposition

• The Court of Appeals affirmed the Defendant’s second-degree murder conviction, concluding that the district court erred in excluding the expert testimony but that such error was harmless (para 1).

Reasons

• GALLEGOS, Judge.
  The Court found that the district court erred in excluding expert testimony regarding the Defendant's predisposition toward impulsive violence due to a low-activity MAOA gene and childhood maltreatment. This testimony was deemed relevant to the question of whether the Defendant had the specific intent necessary for first-degree murder. However, the Court concluded that the exclusion was harmless because the jury acquitted the Defendant of first-degree murder, convicting him instead of second-degree murder, which does not require deliberation as an element. The Court reasoned that the expert testimony would not have supported a defense against the general intent crimes of second-degree murder, voluntary manslaughter, and involuntary manslaughter, for which the Defendant was ultimately convicted (paras 25-36).
  KIEHNE, Judge (specially concurring).
  Judge Kiehne concurred with the decision to affirm the convictions but did not agree that it was necessary to rule on the district court's exclusion of the expert testimony. He argued that the case could be resolved on other grounds, specifically that the expert testimony would not have supported a defense to the charges of second-degree murder, voluntary manslaughter, and involuntary manslaughter, making the analysis of the district court's exclusion unnecessary and non-binding dicta (paras 38-41).
