A 28-year-old man was shot and killed in San Francisco’s Visitacion Valley neighborhood this weekend, authorities said.

City resident Antoine Davis was found suffering from at least one gunshot wound on the unit block of Brookdale Avenue in the Sunnydale public housing complex at 3:27 a.m. Saturday.

He was transported to San Francisco General Hospital, but died upon arrival.

No arrests have been made.

Davis is the third man to be fatally shot in public housing in San Francisco over the past two weeks.

On the Fourth of July, Jamar Samuel, 26, was found face down on the 1000 block of Connecticut Street in the Potrero Hill public housing complex. Five days before, 33-year-old Prince Johnson suffered a gunshot wound to the shoulder on that same block.

Police arrested a father and son in connection with Johnson’s killing, but the father was released after the district attorney said there was insufficient evidence to hold him. The son was held on an unrelated weapons charge.
