BAY CITY, Mich. (AP) — Authorities on Wednesday recovered the body of a man who disappeared after jumping from a pontoon boat in Saginaw Bay.

A fisherman spotted the body of 58-year-old Timothy A. Wallschlager floating in the bay about 300 to 500 yards (275 to 450 meters) from Shelter and Channel Island and notified the Michigan Department of Natural Resources, Bay County Sheriff Troy Cunningham said.

A woman on the boat jumped in to try saving the man, but she too began to struggle, lost consciousness and nearly drowned, Cunningham said. Others on he boat pulled her up with help by three people aboard another boat and a deputy on marine patrol, the sheriff said. The deputy resuscitated the woman.

Wallschlager was not wearing a life preserver, Cunningham said.

Deputies, U.S. Coast Guard personnel, DNR officers and area firefighters all searched for Wallschlager but weather conditions made it difficult.
