Sergio Cortes was 15 when he was shot in a drive-by shooting in Oakland on August 16, 2015. The shooting occurred about 1:56 a.m. near San Antonio Park and the 2000 block of Foothill Boulevard. An unknown person in a passing vehicle opened fire, striking Sergio; he was taken to a hospital and died shortly afterward.

Authorities initially had few details about a suspect or motive. Sergio’s death was among many homicides in Oakland that year—2015 saw 83 homicides—with numerous young victims and ongoing concerns about gang activity and gun violence in parts of East Oakland. Police asked witnesses to come forward, but the case remains unsolved.

If anyone was in the area that early morning or has information about the shooting, please share what you know.
