Donald Schambers, 65, was last seen on April 25, 2017, at a Los Angeles County building. After his disappearance, a search was conducted and his apartment was checked; his computer and cell phone were found there but all of his clothing had been removed, a detail that heightened concern about his welfare.

He was described as 5 feet 6 inches tall, about 140 pounds, with brown hair. Despite extensive efforts, no trace of Schambers has been found and the case remains unsolved.

Any information that could lead to his whereabouts would be valuable to investigators—did anyone see or hear from Donald around April 25, 2017?
