Disposition

• The Supreme Court of New Mexico affirmed the Defendant's conviction for first-degree murder (para 48).

Reasons

• The Supreme Court found no evidence supporting the necessity of a self-defense instruction as the Defendant's actions were not objectively reasonable under the circumstances of the killing (paras 12-18).
  The Court held that the district court did not abuse its discretion in excluding expert testimony on the Defendant's incapacity to form specific intent due to noncompliance with procedural rules and lack of notice to the prosecution (paras 19-34).
  The Court also found no abuse of discretion in excluding expert testimony regarding the survivability of the victim's wounds, as it had little probative value and could confuse the jury (paras 35-38).
  The Court ruled that the district court did not abuse its discretion in excluding additional letters written by the Defendant, as the rule of completeness did not apply in this context (paras 39-43).
  The Court determined that the district court did not abuse its discretion in denying the Defendant's motion for a new trial, as the Defendant's arguments did not amount to trial errors (paras 44-46).
  Finally, the Court concluded that there was no cumulative error as the Defendant received a fair trial and the district court committed no errors (paras 47).
