Mark Thomas Schley, a 29-year-old man, was last seen on December 17, 1984, in Jacksonville Beach, Florida. On that day, Schley left town with a friend and has never been heard from again. His friend, who has since passed away, became the primary suspect in Schley's disappearance, but no conclusive evidence has surfaced. Schley did not return from the trip, and there have been no significant developments in his case over the years.
Schley is described as being 5'10" tall, weighing 140 pounds, with brown hair and blue eyes. He also had a scar on his groin and may have used the last name "Welby." The case has remained unsolved, with no substantial leads emerging since the time of his disappearance. Law enforcement continues to classify it as a missing person case, but foul play has not been ruled out.
Authorities encourage anyone with information regarding his case to contact the Jacksonville Beach Police Department, as his disappearance remains one of the unsolved cases from the 1980s in Florida. Despite the time that has passed, there is still hope that new information may come to light.
Last Seen: Dec 17, 1984
