Gilbert Trevino, 55, of Beaumont, California, was killed in a shooting on January 10, 2018, on the Morongo Indian Reservation near Banning. Deputies responded about 11 p.m. to reports of gunfire at Ramon and Chino roads and found three men had been shot; Trevino was pronounced dead at the scene, one victim was critically injured and a third suffered minor injuries.

A 31-year-old suspect, Adrien Sotomayor, was arrested the next day and charged with one count of murder and two counts of attempted murder. He pleaded not guilty and was held on $2.07 million bail. Sotomayor’s record included a prior conviction for the 2008 beating death of Grant Dodder; he served three years in state prison for that case.

Authorities said the motive was unclear and did not disclose any relationship between the suspect and the victims; deputies continued to gather evidence and interview witnesses. If anyone has information about the shooting or knew Gilbert Trevino, please share what you remember.
