SAN FRANCISCO (KRON) — Tensions briefly boiled over inside a church on Thursday during a funeral service for Banko Brown. The 24-year-old transgender Black man was shot and killed in April by a Walgreens security guard.

The service began at 10:30 a.m. in Third Baptist Church in San Francisco. After a few tense moments of people shouting, arguing, and rising to their feet between pews, things appeared to calm down again and the service resumed.

Brown and the security guard got into a deadly confrontation inside a Walgreens store on Market Street. Brown was unarmed when the guard opened fire.

San Francisco District Attorney Brooke Jenkins said, based on surveillance footage, witnesses, and statements from the guard, her office will not to prosecute the guard, 33-year-old Michael Earl-Wayne Anthony, for killing the shoplifter.

Jenkins’ decision has many in the community outraged and demanding justice for Brown.

When the surveillance footage of the shooting was released, protestors took to the streets calling for justice.

California Attorney General Rob Bonta said he plans to review the case to see if the state can bring charges against the security guard.

Anthony was arrested by the San Francisco Police Department on suspicion of homicide immediately after the killing. Anthony told homicide detectives that he believed he was in danger because Brown made a “sudden movement,” and that Brown threatened to stab him while they were wrestling inside the store. The guard remains freed from jail.
