Olajawon Walker, 24, of San Pablo, California, was shot and killed the evening of April 24, 2020, on the 1000 block of Mariposa Avenue in Rodeo. Deputies responded about 7:50 p.m. and found Walker lying in the street with a gunshot wound; paramedics pronounced him dead at the scene.

Investigators determined Walker had been fatally shot but initial circumstances were sparse. The Contra Costa County Sheriff’s Office and the District Attorney identified 30-year-old Angelo Ramirez of San Pablo as the primary suspect, charged him with murder and obtained an arrest warrant. Ramirez was believed to have fled the area and was being sought by the Sheriff’s Office and the U.S. Marshals Service; authorities said he was considered armed and dangerous and warned that anyone harboring him could face accessory charges.

Anyone with information about the shooting or Ramirez’s whereabouts is asked to come forward.
