Martin Heredia, 20, was shot and killed on June 8, 2016 after an incident the night before at his family’s home in King City, California. On June 7 he and three friends briefly left the residence to buy food and returned; as Heredia stepped outside to get a bag of chips from a friend’s vehicle, a black pickup containing John Samuel Trivino and other men drove by. Trivino exited the truck and opened fire on Heredia and the house. Heredia was struck and died shortly afterward.

The investigation into the slaying stretched over several years and involved multiple law enforcement agencies. The case has been central to the family’s long search for answers; Martin’s sister Roxanna described the profound effect his death had on their lives. Few public details remain about the investigative steps taken in the intervening years.

If anyone knew Martin, saw the vehicle that night, or has information about the shooting, please share what is known with investigators.
