A 28-year-old man was shot and killed Saturday morning in what police say is the 27th homicide for San Francisco in 2015, and the third such slaying in the city's public housing in the last two weeks.

According to San Francisco Police Department spokesperson officer, Grace Gatpandan, police were sent to Brookdale Avenue and Santos Street at 3:27 Saturday morning after an area ShotSpotter alert indicated that there was gunfire in the area.

When they arrived, they found San Francisco resident Antoine Davis on the ground, bleeding from at least one gunshot wound to his torso, Gatpandan says. Though he was transported to San Francisco General Hospital, he succumbed to his injuries and was pronounced dead at 4:12 a.m.

Witnesses told police that the suspect was a man in his early 20s who was armed with a handgun, Gatpandan says. At publication time, police did not have any additional suspect details or information on a motive for the shooting, but Gatpandan did note that SFPD's Gang Task Force is involved in the investigation.

It has not been determined whether Davis was the intended target, Gatpandan says.

According to Bay City News, a nearby residence was also struck by gunfire during the shooting, but the residents inside were uninjured.

Davis' shooting, which took place in the Sunnydale Housing Development, is the third fatal shooting in a San Francisco Public Housing development since June 29. That's when 33-year-old San Francisco resident Prince Johnson was shot and killed on the 1000 block of Connecticut Street in the Potrero Terrace public housing complex.

Though 42-year-old Jabar Hickman and his 25-year-old son Carneil Hickman-Butler were initially arrested for Johnson's slaying, the District Attorney's office opted not to charge them and they were released.

Then, on July 4, 26-year-old Jamar Samuel was shot and killed on that same block in San Francisco's 26th homicide of 2015. No arrests have been made nor has any suspect information been released, in his death.
