Allen Calloway, 32, was shot and killed Friday afternoon at about 2 p.m. at Herz Playground near Hahn Street and Visitacion Avenue in San Francisco’s Visitacion Valley. According to police, Calloway was leading a group of children, including his 10-year-old son, in a game of dodgeball when a suspect walked up and shot him several times. He later died at the hospital.

Calloway had been a former gang member who turned to community work; at the time he was employed part time as an outreach worker for Together, United, Recommitted Forever (TURF). He had been sentenced in 2007 to one year and seven months in federal prison for selling cocaine for the Down Below Gang. Dozens of children witnessed the attack, grief counselors were brought to the playground, and police increased their presence. The shooting suspect has not been identified and remains at large.

Did anyone see or hear anything at Herz Playground around 2 p.m. that Friday, or does anyone have information about who approached the group?
