Mario Yokoi, 38, of Dixon, California, was shot and killed on July 21, 2018, after a fight at a large house party in the 1300 block of Bello Drive. The confrontation that led to his death occurred near Folsom Downs Circle after Yokoi confronted a group he believed had been involved in the initial fight. A 43-year-old man who tried to intervene was also shot multiple times and taken to a hospital.

Investigators later arrested two suspects: a 17-year-old boy from Sacramento was arrested August 21, 2018, on suspicion of robbery and attempted murder and booked into Solano County Juvenile Hall; and 20-year-old Lucas Davis of Sacramento was arrested October 24, 2018, on suspicion of assault with a deadly weapon and booked into Solano County Jail. The Dixon Police Department continued to seek additional suspects and information.

If anyone attended that July 21 party or has information about who was involved, please share what is known with investigators.
