1 OPINION
2 VIGIL, Justice.
3 {1} Defendant Castulo Aragon, Jr., was convicted by a jury of the first-degree
4 murder of his wife, Maria Aragon (Victim), and three counts of tampering with
5 evidence. Defendant chose to represent himself at the trial. On direct appeal to this
6 Court he now raises approximately twenty various arguments that can be distilled
7 to: (1) issues related to the admission of lay testimony; (2) issues related to the
8 admission of expert testimony and whether Defendant’s right to confront witnesses
9 under the Sixth Amendment was violated; (3) issues related to the sufficiency of the
10 evidence supporting Defendant’s convictions; (4) whether the count three conviction
11 is barred by double jeopardy; and (5) whether prosecutorial misconduct occurred.
12 We conclude that none of Defendant’s arguments warrant a new trial, and we affirm
13 the jury’s verdict on counts one, two and four. However, we remand the case to the
14 district court for dismissal of Defendant’s count three conviction for tampering with
15 evidence because it is barred by double jeopardy.
16 I. BACKGROUND
17 {2} Victim and Defendant met in December, 2015, and married four months later,
18 in April, 2016. Victim and Defendant knew each other for a total of fifteen months
19 when she was murdered in March, 2017, and they were married for eleven of those
1 months. On Monday, March 6, 2017, at approximately 9:40 a.m., Victim was found
2 deceased by the side of the road along Highway 285 north of Roswell, New Mexico.
3 She was lying face down near some large piles of gravel. Her bloody sweater was
4 on backward and her hair was matted with blood.
5 {3} There was no evidence of blood dripping down onto Victim’s clothes, despite
6 significant head trauma. There was no blood on the ground, even though Victim had
7 significant injuries. Nor was there evidence that Victim walked to the location where
8 she was discovered. The evidence suggested that Victim was transported to the
9 scene, was “deposited” where she lay, and was not there long before she was
10 discovered.
11 {4} Expert witness testimony revealed that Victim received three different types
12 of fatal injury. She was strangled, stabbed in the chest, and struck in the head with a
13 blunt object. Victim lived for six to twenty-four hours from the time of the head
14 injuries, which resulted in internal skull fracture and lacerations. The lack of ligature
15 marks suggested manual strangulation, although the evidence was inconclusive.
16 Victim’s jaw was badly broken. A police officer with twenty-four years of
17 experience who was admitted as an expert in crime scene investigation testified that
18 this was “one of the more violent cases that [he had] see
