Gabriel Anguiano-Bautista, 22, was shot and killed in San Francisco on August 29, 2007. His killing remains unsolved and is listed among the city’s cold-case homicides from that year.

The case came during a year when California recorded 2,258 homicides; many fatalities that year involved gun violence, gang activity, or interpersonal conflict. Investigators have faced a shortage of witnesses and limited physical evidence in this and similar cases, and San Francisco authorities have offered substantial rewards—reported between $50,000 and $250,000—on cold cases to encourage tips.

Anguiano-Bautista’s family continues to seek answers as the city grapples with unresolved violent loss. If anyone has information about his death or remembers events from late August 2007 in San Francisco, please share what is known with the San Francisco Police Department.
