, 17, of Weed was visiting his family at the Golden Gate public housing complex in Marin City when he was shot several times at around 12:16 a.m. Police arriving at the scene of the shooting attempted to revive the boy, but he was pronounced dead a short while later.
Investigators worked throughout the morning trying to piece together events and determine why Williams, who was not known in Marin City, was shot. Williams' older sister told CBS Bay Area that the killing was a case of mistaken identity.
"It happened for absolutely nothing... basically, somebody just got the wrong thing... got him confused. They didn't know, he's not from out here," the woman said.
Williams is at least the tenth child to be shot to death in 2013. In the last week, the following minors have died in shooting incidents:
