Summary based on the NamUs case record (MP7530) and 4 other sources
William R. Hennig, aged 33, was last seen on July 11, 1980, in Daytona Beach, Florida. He told his family that he was heading to Fort Lauderdale for business, but he never returned, and his whereabouts remain unknown. At the time, Hennig worked in the insurance industry, and his disappearance raised concerns due to his abrupt and unexplained departure. Some reports suggest that he may have traveled to Ohio, California, or even the Bahamas after leaving Daytona Beach, though no evidence has been found to support these claims.

Hennig was officially reported missing on February 4, 1981. He stood 5'10" tall, weighed 170 pounds, and had brown hair and brown eyes. He sometimes wore a hairpiece and had a distinctive scar on his back. His case has been classified as missing, and the details surrounding his disappearance remain limited. Despite investigations, there have been no significant leads, and his case is still unresolved.
