Chris Garcia was 16 when he was killed in San Francisco on June 30, 2007. The case remains unsolved and is listed among the city’s cold homicides from that period.

Authorities say the investigation has not produced an arrest; police continue to seek witnesses and tipsters and have offered rewards for information that might lead to a breakthrough. Garcia’s death was one of many that contributed to a notably violent year in the city, and his family and community remain without answers.

Anyone who knew Chris, saw something on or around June 30, 2007, or has information that could help investigators is asked to come forward.
