Details of Disappearance
Demyon was last seen at around 6.15 pm on January 13, 1997 driving away from his Cockeysville, Maryland, house to go a nearby motel to use a pay phone; the home phone had been disconnected. He was reported missing by his wife the following day. His car, a 1989 dark blue Pontiac Bonneville, was found on February 20, 1997 in the 1800-block of North Calvert Street in Baltimore City. No evidence of foul play was discovered.
Demyon was the vice president of Safety/Sight Incorporated in Cockeysville, a firm founded by his late father. He was an avid gambler, and frequented Las Vegas, Atlantic City, and the horse tracks, and was apparently in debt to several gambling associates.
