John Clyde Perrin was a 25-year-old man who disappeared after being last seen in Menlo Park, California. Public missing-person databases continue to list him as missing, and there is no publicly posted confirmation that the case has been resolved.
At the time he vanished, Perrin had just graduated from Stanford University’s law school. Accounts available in long-running public case summaries describe him as a conscientious objector to the Vietnam War who had been convicted for refusing induction into the U.S. armed services; those same summaries note the conviction was under appeal when he disappeared and was later affirmed by the Ninth Circuit.
One of the most discussed leads in the public record is a report that a young man was rescued from San Francisco Bay the morning after Perrin was last seen.
According to published case narratives, the rescued man was taken to a hospital, provided clothing, and gave the name David Herrin before leaving and vanishing from view; his identity has not been publicly confirmed, but Perrin’s family has believed the man may have been him.
Descriptions across official postings identify Perrin as a White male with blonde hair and brown eyes, approximately 5'11" and about 155 pounds, with a notable scar on his heel caused by a motorcycle wheel; he was also known by the nickname Johnny. Records also note he was born in Bristol, Tennessee, and grew up in Virginia, and that surviving siblings have continued searching for answers.
The timeline is not perfectly consistent across public listings. Some sources provide a specific last-contact date, while at least one official listing displays a generic date while stating only that he was last seen in 1970, suggesting that parts of the chronology may be incomplete in publicly available records. In any case, he remains publicly listed as a missing person, and the investigating agency continues to be identified as the Menlo Park Police Department.Last Seen: Jun 23, 1970
