Carlos L. Martinez, a 40-year-old Hispanic man, was killed outside his home on Armoridge Drive in Magna, Utah, on May 4, 2014. A verbal dispute earlier that day between Martinez and two younger males over gang representation escalated; Martinez and another person later sought the two men out. One of those involved, 17-year-old Joe Perez, returned to Martinez’s house in a gray car driven by another male. As Martinez came out of his garage, Perez walked up and fired multiple shots. Officers found Martinez bleeding in front of the garage; he was taken to Intermountain Medical Center and later died of his injuries. Investigators recovered nine spent 9mm shell casings at the scene.

Detectives later identified Perez as one participant in the earlier argument. The driver, Skyler Burnasconi, told police he had driven Perez to Martinez’s home, witnessed the shooting, and said Perez hid the weapon in the car and retrieved it the next day. Martinez’s daughter also identified Perez from a Facebook photo as one of the men in the argument. Perez was charged as an adult with murder and other felonies; Skyler Burnasconi was not charged. The family said the killing grew out of Perez feeling disrespected after the earlier confrontation.

Can anyone who knew Carlos or who was in Magna that week in 2014 provide information about the earlier dispute or the gray car seen in the neighborhood?
