William R. Hennig was 33 when he was last seen in Daytona Beach, Florida, on July 11, 1980. He told his family he was heading to Fort Lauderdale for business but never returned and was not reported missing until February 4, 1981. At the time he worked in the insurance industry.

Hennig was 5 feet 10 inches, about 170 pounds, with brown hair and brown eyes. He sometimes wore a hairpiece and had a distinctive scar on his back. Some reports say he may have traveled to Ohio, California, or the Bahamas after leaving Daytona Beach, but no evidence supports those claims and there have been no significant leads.

Who knew William or his routines in 1980 and might have information about where he went after July 11?
