20 for Appellee 1 OPINION

2 BACON, Justice.

3 {1} Defendant has filed a motion for rehearing. We grant the motion for rehearing.

4 We withdraw the opinion filed July 14, 2025, and substitute the following in its

5 place.

6 {2} This is a capital appeal pursuant to Rule 12-102(A)(1) NMRA wherein Mark

7 R. Valencia (Defendant) raises four challenges. First, Defendant argues his

8 convictions on two counts of first-degree murder (willful and deliberate), contrary

9 to NMSA 1978, Section 30-2-1(A)(1) (1994), and one count of second-degree

10 attempt to commit first-degree murder (willful and deliberate), contrary to NMSA

11 1978, Section 30-28-1(A) (1963, amended 2024) and Section 30-2-1(A)(1), must be

12 reversed because the district court denied his request for the jury to be instructed on

13 diminished capacity to form requisite intent due to voluntary intoxication. Second,

14 Defendant argues his convictions for fourth-degree aggravated assault with a deadly

15 weapon, contrary to NMSA 1978, Section 30-3-2(A) (1963), and attempt to commit

16 first-degree murder, contrary to Section 30-28-1(A) (1963), violated double

17 jeopardy. Third, Defendant argues his convictions for fourth-degree shooting at a

18 dwelling or occupied building, contrary to NMSA 1978, Section 30-3-8(A) (1993),

19 and misdemeanor negligent use of a deadly weapon, contrary to NMSA 1978, 1 Section 30-7-4(A)(2) (1993), violated double jeopardy. Fourth, Defendant argues

2 the district court lacked statutory authority to increase his basic sentence for attempt

3 to commit first-degree murder with a three-year firearm enhancement.

4 {3} Defendant’s convictions on both charges of first-degree murder and on the

5 charge of attempted first-degree murder are reversed and remanded for a new trial

6 because Defendant was improperly denied his request for voluntary-intoxication

7 jury instructions. As a consequence of the reversal, we do not address Defendant’s

8 additional claims relating to the charge of attempted first-degree murder: his double-

9 jeopardy claim involving aggravated assault and his claim regarding the firearm

10 enhancement. Defendant’s convictions for shooting at a dwelling or occupied

11 building and negligently using a deadly weapon are affirmed.

12 I. BACKGROUND

13 A. Facts

14 {4} During the evening of December 11, 2021, Defendant and his girlfriend,

15 murder-victim Eva Aragon (Aragon), went to socialize with Aragon’s uncle, David

16 Sturgeon (Sturgeon), at Sturgeon’s house in Pecos, New Mexico. Sturgeon and his

17 friend, murder-victim Steven Singer (Singer), were at the house drinking beers

18 before Defendant and Aragon arrived. Defendant and Aragon had also been drinking

19 prior to meeting up with Sturgeon and Singer. 1 {5} Once at the house, Defendant, Aragon, and Singer took shots of vodka, and

2 progressed to simply passing around the bottle. They finished one bottle and started

3 sharing a second. Around seven or eight o’clock, Singer gave Defendant a haircut,

4 which started an argument because Defendant was not happy with the result. Singer

5 and Defendant argued and pushed each other, and Defendant then retrieved a gun

6 from his vehicle. While Defendant was retrieving the gun, Sturgeon closed and

7 locked the front door of the house. Defendant shot at the front door at least eight

8 times, eventually shot the lock, and opened the door.

9 {6} Singer and Aragon were standing just inside the door. Defendant shot Singer

10 in the head just below the left nostril, killing him. Aragon got down on the floor next

11 to Singer, and Defendant then shot Aragon between the eyes, killing her as well.

12 {7} Defendant pointed the gun at Sturgeon and said he would shoot him, too.

13 Sturgeon hid in a closet and called 911. Defendant walked around the house, and

14 repeatedly said he was going to find and shoot Sturgeon. Defendant “shot the whole

15 house up,” with one bullet going into the closet where Sturgeon was hiding.

16 {8} Police were dispatched around 9:26 p.m. and arrived at the scene within

17 fifteen minutes. The scene was quiet when they arrived. They checked each vehicle

18 in front of the house for people, finding Defendant slumped over the steering wheel

19 in the driver’s seat of Sturgeon’s van. Defendant was not moving, so the police did 1 not know whether he was deceased or asleep. He had an unlit cigar or cigarette in

2 his hand, smelled of alcohol, and was not wearing shoes. Police woke Defendant,

3 but it took a while to get his attention. Defendant was put in a patrol car without

4 incident. While in the patrol car, he repeatedly hung his head and mumbled

5 incoherently to himself.

6 {9} At approximately 2:00 a.m., agents questioned Defendant about what

7 happened. The agents noticed Defendant had slow speech, as well as bloodshot and

8 watery eyes. Defendant confessed to the shootings. He claimed he shot Singer

9 because Singer started “coming at him” and he shot Aragon because she got in the

10 way. Defendant denied threatening Sturgeon and also said he did not remember

11 firing any shots after shooting Singer. Also, he told the agents he had a lot to drink—

12 half a fifth of vodka and two beers. Defendant was subsequently charged with, inter

13 alia, the murders of both Singer and Aragon. Additional facts are provided in the

14 analysis sections herein as relevant.

15 B. Procedural History

16 {10} In August 2023, Defendant was tried by a jury on two counts of first-degree

17 murder (willful and deliberate), attempt to commit first-degree murder (willful and

18 deliberate), aggravated assault with a deadly weapon, shooting at a dwelling or

19 occupied building, and negligent use of a deadly weapon. Defendant’s theory of the 1 case on both counts of first-degree murder and on attempt to commit first-degree

2 murder was that he was too intoxicated to form the requisite mental state—deliberate

3 intention—required to commit the offenses. He requested a voluntary intoxication

4 jury instruction pursuant to UJI 14-5110 NMRA for both charges of first-degree

5 murder, and a like instruction pursuant to UJI 14-5111 NMRA for the charge of

6 attempt to commit first-degree murder. The district court denied his request,

7 reasoning the instructions were not supported by the evidence. Defendant was found

8 guilty on all charges. The jury also found he “used” a firearm in the commission of
