Alvaro Palma, 30 and a San Francisco resident, was shot to death around 12:30 a.m. on May 28, 2017, on the 4200 block of Mission Street outside a bar called La Oficina. San Francisco Police detained David Sanchez, 44, a security guard at the bar, at the scene; officers found him in possession of a firearm and narcotics. Sanchez was charged with felony murder, possession of narcotics for sale, and possession of a controlled substance while armed and was held in San Francisco County Jail without bail.

The killing prompted calls from neighbors and officials for La Oficina’s permit to be revoked; Supervisor Ahsha Safai publicly urged action, and Palma’s family campaigned for the bar’s closure while demanding justice. Prosecutors described Sanchez’s actions as premeditated and dangerous, while the defense argued he acted in self-defense. What did readers in the neighborhood see or hear that night, and does anyone have information that could help clarify what happened?
