Constantine Mustric, 76, went missing from Los Angeles on August 25, 1986 after leaving his home for a walk and never returning. He was described as a white male, 5 feet 7 inches tall, 125 pounds, with grey hair and brown eyes.

Despite searches, no trace of Constantine was found and the circumstances of his disappearance remain unclear. The case is unsolved and there is very little public information about what may have happened; authorities noted his age and the time elapsed but no evidence has been uncovered to confirm any specific outcome.

Did anyone in Los Angeles at that time see Constantine or have information about where he might have walked that day?
