On the evening of April 27, 2006, Hugo Rosas-Pardo, 25, was shot and killed outside his home in the 3000 South block of 5990 West in West Valley City, Utah. The shooting followed a dispute with coworker Victor Herrera Briones over a truck Rosas-Pardo and his wife had bought that turned out to have a faulty engine.

A physical altercation at their construction job and an earlier threat by Briones were reported; Rosas-Pardo’s 16-year-old nephew warned him not to go outside but he did and was struck multiple times in his driveway after Briones allegedly drew a handgun and fired about six shots. Briones fled but was stopped near Barstow, California the next morning; a 10 mm handgun was found in his pickup and he was arrested on first-degree felony murder and a weapons charge.

Over the following years Briones spent extensive time at the Utah State Hospital for competency restoration, and in November 2013 a judge ordered the start of civil commitment proceedings after clinicians concluded he was unlikely ever to be competent for trial.
