Summary based on the NamUs case record (MP38120) and 6 other sources
Clayton Nobuo Onosaki, a 20-year-old man, was last seen on July 1, 1978, in Los Angeles, California. At the time, Clayton had written a letter to his mother, informing her that he might travel to San Diego with a coworker. However, he was never heard from again after that communication. Despite his planned trip, it is unclear whether he ever actually made the journey to San Diego. No trace of him or further details about his whereabouts have been uncovered since his disappearance.

Clayton was living in Los Angeles at the time of his disappearance and is described as a Pacific Islander with black hair and brown eyes. Standing at 5'2" and weighing around 150-170 pounds, he had no distinguishing tattoos or marks. His case remains unsolved, and there has been little media or investigative attention on his disappearance over the years.

Despite the passage of time, no new leads or evidence have emerged. His case is still classified as missing, with no conclusive answers for his family. Law enforcement continues to seek information that could shed light on what happened to Clayton on that summer day in 1978.
