Police are searching for three suspects in a South San Francisco shooting that left two dead, seriously injured another, and left four more with injuries.

One of the surviving victims was in critical condition late Wednesday and the other three were taken to the hospital with non-life-threatening injuries.

Police are looking into whether the Wednesday night shooting was gang-related and said the shooting took place in a neighborhood that’s prone to gang activity.

Police were called to Eighth Lane and Linden Avenue about 7:14 p.m. after reports of multiple gunshots, said South San Francisco police Sgt. Joni Lee.

When officers arrived, they found two dead on Eighth Lane, an alley surrounded by homes.

Police didn’t identify the victims, but Yvonne Ruiz, 20, said her brother, 19-year-old Gonzalo Avalos, had been shot and killed.

Police also found another injured victim on the same street. That person’s condition was unknown.

The scene was tense as people cried and sought information about the victims. Streets were blocked off, and crowds of residents gathered near emergency vehicles.

One woman, who was pressed against yellow caution tape, begged police to tell her whether her nephew was among the casualties. She walked away without an answer.

Many onlookers said they were frustrated about previous unsolved homicides.

Lee said the suspects were driving a 2000 or 2002 brown Chevrolet Impala with tinted windows.
