Summary based on the NamUs case record (MP55053) and 6 other sources
Ryo John Stanistreet, a 28-year-old U.S. Air Force veteran stationed at Vandenberg Air Force Base, went missing on August 30, 1982, while diving off the coast of Point Conception, California. Ryo was part of a group diving in the Pacific Ocean when their boat encountered distress. It is believed that he may have been on a small raft at the time of the incident. The raft was located later, but Ryo was never seen again. Despite extensive search efforts, he has remained missing ever since.

At the time of his disappearance, Ryo was described as standing 6 feet tall and weighing around 160 pounds. He was last seen wearing diving gear, and no other personal items or evidence have been recovered. The case has remained unsolved for decades, with authorities continuing to seek any new information that could shed light on his fate.

Ryo's case is classified as a missing person, and anyone with information is encouraged to contact the appropriate law enforcement agencies handling the investigation.
