Delaware State Police are investigating the death of an elderly man whose body was found on his boat in Sussex County Saturday afternoon.

Troopers found the 71-year-old man unresponsive on his boat, which was docked at a private marina behind his home on Paleo Way in Millsboro, police said.

The man's body was turned over to the state Division of Forensic Science for an autopsy.

Police don't suspect foul play, but they're asking anyone who may have information as to how the man died to call Detective Coleman of the Troop 4 Criminal Investigations Unit by calling 302.644.5020.
