David Bustamante, 37, was shot multiple times and killed on December 25, 2015, in the parking lot of an In-N-Out Burger in Hesperia, California. The shooting happened about 3:37 p.m. after several 911 callers reported gunfire. Bustamante, known as Mouse, had been working on a tattoo for a client when he received a call and drove to the restaurant carrying tamales his mother had made. He was found near his vehicle with multiple gunshot wounds and later pronounced dead at Desert Valley Hospital.

Authorities identified and arrested 47-year-old Johnny Michael Oliva of West Covina shortly after the shooting; he was taken into custody near his home and held at the West Valley Detention Center. Investigators say Oliva lured Bustamante to the parking lot under the pretense of repaying a debt, ambushed him and shot him six times in the chest, allegedly shouting La Eme during the attack. The case against Oliva relied on eyewitness accounts, cell phone records and restaurant surveillance footage, and investigators reported attempts to intimidate witnesses. Oliva was convicted of first-degree murder with special circumstances and sentenced to life without the possibility of parole.

Does anyone have memories of Bustamante, his nickname Mouse, or the Hesperia area that could shed light on his life or the events that led to that day?
