Summary based on the NamUs case record (MP24251) and 4 other sources
William Sigfredo Blanco, 29 years old, was last seen on April 30, 1992, during the chaotic days of the Los Angeles riots. Blanco left his apartment on Country Club Drive in the Mid-City district of Los Angeles with a group of friends, reportedly to participate in looting activities amidst the unrest. He never returned home after that evening, and his whereabouts remain unknown to this day.

At the time of his disappearance, William was 5'5" tall, weighed 140 pounds, and had brown hair and brown eyes. He also had a distinctive "W" tattoo on his left arm. Despite the high visibility of the events surrounding the 1992 riots, there have been few leads in his case, and he has not been located. The case remains unsolved, and authorities encourage anyone with information to contact the Los Angeles Police Department, who continue to investigate his disappearance.
Last Seen: Apr 30, 1992
