On the morning of April 11, 2015, Tyson Macartin Antonio, a 23-year-old Hispanic/Latino man from Fort Duchesne, was found dead in his mother’s home in Ballard, Utah. Investigators determined he had been shot in the head and ruled the death a homicide.

Police identified Tyson’s older brother, 27-year-old Craig A. Antonio, as the primary suspect. Charging documents say the brothers had recently used methamphetamine together and that an argument ended when Craig allegedly shot Tyson with a rifle. Craig was arrested and charged with first-degree felony murder; both brothers had prior drug possession convictions.

A competency evaluation followed. In August 2015 an 8th District Court judge found Craig Antonio not competent to stand trial and ordered him committed to the Utah State Hospital for treatment to restore competency. The criminal case was paused pending any change in his mental status.

Does anyone have information about Tyson, his movements in Ballard, or the night of April 11, 2015?
