Summary based on 1 source
Gregory Allen Valladao, a 35-year-old man from Tuolumne County, California, has been missing since March 10, 1991. On the day of his disappearance, Valladao left his residence on Italian Bar Road with the intention of driving a short distance to a friend's house. However, he never reached his destination and has not been seen or heard from since.

At the time he went missing, Valladao was described as a 6'0" tall, 160-pound white male with brown hair. He had distinctive features, including one green eye and one glass eye that bore a Harley-Davidson emblem. His long hair was styled in a braid, and he had a full beard. Additionally, he had numerous tattoos on his upper torso.

Following his disappearance, Valladao's vehicle was discovered abandoned off the road in the Star Ridge area, which was not far from his home. Despite an extensive search of the surrounding area, no trace of Valladao was found. The Tuolumne County Sheriff's Office is investigating his case, but few details have been made available to the public.
