Miguel Alvarez was 17 when he was shot and killed in San Francisco during the early morning of December 9, 2015. The shooting occurred on Holladay Avenue, just outside the Mission District. Friends transported Alvarez to San Francisco General Hospital, but he later died from multiple gunshot wounds to the torso.

Police were alerted by the city’s gunshot detection system, SpotShotter, and arrived after Alvarez had already been taken to the hospital. The Gang Task Force investigated, but no arrests have been made and no suspects have been publicly identified. Alvarez’s death was one of several homicides that increased concern about violence in the Mission District. A memorial with roses and prayer candles honoring Alvarez was later set up at 24th and Capp Streets, away from the crime scene.

If anyone has information about what happened that night, authorities would welcome tips.
