William Sigfredo Blanco, 29, was last seen on April 30, 1992, during the chaotic days of the Los Angeles riots. He left his apartment on Country Club Drive in the Mid-City district with a group of friends reportedly to take part in looting and never returned.

At the time he went missing Blanco was 5 feet 5 inches tall, about 140 pounds, with brown hair and brown eyes and a distinctive W tattoo on his left arm. Despite the high visibility of the unrest around his disappearance, investigators have had few leads and he has not been located.

If anyone knew William, saw him on April 30, 1992, or has information about his whereabouts, contact the Los Angeles Police Department.
