KENOSHA,EAI Community  Wis. (AP) — Wisconsin officials were working Thursday to retrieve a boat that sank during the search for a missing diver in Lake Michigan.

Multiple agencies joined the search for Patrick Kelly, 72, of Winthrop Harbor, Illinois, after he failed to surface Tuesday while diving around the wreck of the S.S. Wisconsin about 6 miles (9.7 kilometers) off the coast of Pleasant Prairie. Searchers recovered Kelly’s body Wednesday.

The Kenosha County Fire and Rescue Association’s search boat started taking on water Tuesday afternoon about 4 miles (6.4 kilometers) from shore, WDJT-TV reported. Other boats rescued the eight crew members and most of their equipment before the vessel sank about 65 feet (19.8 meters) to the bottom of the lake.

Kenosha County officials said they were working with the state Department of Natural Resources to retrieve the boat.
