Police say three people, including a 9-year-old boy and his father, were shot dead outside a liquor store in San Bernardino.

San Bernardino Police Sgt. Vicki Cervantes said Saturday the shooter was waiting for the victims outside the store late Friday.

When they walked out, the shooter approached them from behind, pulled a gun and fatally shot them all.

The victims were identified as 25-year-old Samathy Mahan, 26-year-old Travon Lamar Williams and 9-year-old Travon Williams.

Cervantes says the Williamses are father and son.

While the motive is under investigation, Cervantes says Mahan is a documented gang member who was recently paroled. She says investigators believe he was the intended target.

The shooter fled on foot, and police are asking for the public's help to identify him.
