Richard Frank Plechner, a 31-year-old man, was last seen on July 25, 1975, in Huntington Beach, California. Standing 6'1" and weighing 240 pounds, with brown hair and hazel eyes, Plechner disappeared without a trace, and very few details about the circumstances surrounding his disappearance are available. His case remains unresolved, with no significant leads or developments reported over the decades since he was last seen.
Authorities have listed his case as "endangered missing," and it has been documented in multiple missing person databases.
The Huntington Beach Police Department continues to be the lead investigating agency in Plechner's case, but no substantial progress has been made. Investigators still encourage anyone with information that could help solve this long-standing mystery to come forward.
This case remains open, with hope that new information might eventually come to light.Last Seen: Jul 25, 1975
