Facts

• On May 22, 2009, Marino "Reno" Leyba fatally shot his pregnant girlfriend, Sarah Lovato, and her father, Bennie Lovato, after entering their apartment with a firearm. The State charged Leyba with two counts of first-degree murder, aggravated burglary, tampering with evidence, and criminal abortion, though the criminal abortion charge was dismissed before trial. The State's case included evidence of Leyba's increasingly violent and controlling behavior towards Sarah, notably through the admission of Sarah's diary, which detailed her fears and experiences of domestic violence at Leyba's hands. Leyba's defense centered on his claim that he did not plan the killings and believed he was acting in self-defense (paras 2-5).

Procedural History

• [Not applicable or not found]

Parties' Submissions

• Plaintiff-Appellee (State): Argued that Leyba entered the Lovato apartment without permission with the intent to kill Sarah, supporting this with evidence of Leyba's violent behavior towards Sarah, including specific acts of domestic violence detailed in Sarah's diary (paras 3, 7-8, 12).
• Defendant-Appellant (Leyba): Contended that he did not plan to kill Sarah and her father, asserting that he acted in self-defense. Leyba admitted to shooting both victims but denied any premeditation. He also challenged the admissibility of Sarah's diary and his booking photograph, and argued that the jury instructions co-authored with the State were erroneous (paras 4-6, 34).

Legal Issues

• Whether the diary of the decedent, admitted into evidence, constituted inadmissible hearsay, thereby prejudicing the defense.
• Whether the admission of Leyba's booking photograph was prejudicial and constituted an error.
• Whether the jury instructions regarding Leyba's mental disease or disorder were properly presented.

Disposition

• The convictions for first-degree willful and deliberate murder, felony-murder, and aggravated burglary were reversed, and the case was remanded for a new trial. The conviction for tampering with evidence was not appealed by the defendant (para 45).

Reasons

• The Supreme Court of New Mexico, per Justice Richard C. Bosson, found that the diary entries were inadmissible hearsay not covered by any exception, and their admission into evidence was not harmless but prejudicial, necessitating a reversal of the convictions. The Court also noted that the booking photograph of Leyba should not have been admitted due to its irrelevance and potential for prejudice. Regarding the jury instructions, the Court suggested that instructions on mental disease or disorder should have been included as an element of each specific intent crime, rather than as separate instructions. The Court's decision was unanimous, with all justices concurring (paras 7-44).
