Juan Diaz-Ochoa, 21, of Oakland, was shot on October 14, 2020, and died of his injuries after being taken to hospital. The midday shooting happened around 12:47 p.m. in the 1900 block of 84th Avenue in East Oakland. Three friends were involved in a street confrontation with several other people when at least one person opened fire; a 19-year-old friend, Jorge Martinez, died at the scene and an 18-year-old man was wounded.

Investigators say the incident grew out of a dispute over the theft of a firearm. Witnesses described Martinez as having taken a gun from a man known as Billy Bob and the two agreeing to settle it with a street fight. During the altercation, 28-year-old Hasan Dbouk allegedly became agitated and opened fire. Dbouk was later arrested and charged with multiple felonies, including two counts of murder, attempted murder and kidnapping after a standoff at a shoe store on October 22, 2020.

Who in the neighborhood might have seen the confrontation on 84th Avenue or knows more about the dispute over the gun?
