The two girls, 15, and 16, did everything together. On Sunday, they died together.
Bobbie Sartain, 16, and Raquel Gerstel, 15, were shot "multiple times" at around 6 a.m. on Sunday near Brookdale Park in East Oakland, according to reports.
The two girls met in Alameda, where Raquel grew up before moving to San Leandro, according to the Oakland Tribune. Raquel attended Arroyo High School in San Lorenzo.
The slaying was "overkill," according to police interviewed by the San Francisco Chronicle. At least 36 shots were fired, and Raquel was "full of bullets," according to a witness who arrived on scene to see the girls with multiple wounds. Raquel was "found crawling... as she cried out for help." Bobbie had bullet wounds in her face and back.
The area was known for being close to trouble spots in Oakland, but the neighborhood is described as tight-knit, and not a regular spot for violence, the newspapers reported.
Police have no motive and no suspects. The girls were Oakland's 114th and 115th homicide victims of the year.
