Summary based on the NamUs case record (MP17636) and 6 other sources
Gary Vaughn Sizemore, a 38-year-old man, was last seen on January 1, 1979, in Hawthorne, California. At the time of his disappearance, he was described as a white male standing 6'1" tall and weighing around 160 pounds, with brown hair and brown eyes. He had a noticeable scar on his left forearm. Despite his physical identifiers, no details about his clothing, jewelry, or personal belongings at the time of his disappearance were available.

The circumstances surrounding Sizemore’s disappearance remain unclear, with few leads emerging over the years. His case is classified as a missing person, and his dental records are on file for potential identification purposes, though fingerprints and DNA were not available at the time of his case filing. The investigation remains open, with the Hawthorne Police Department continuing to encourage anyone with information to come forward.

Sizemore's case has not received major updates since his disappearance, and it remains one of many unresolved cases from the late 1970s in Southern California. His profile is included in national missing persons databases like NamUs in hopes of generating new leads.
