DULUTH (AP) -- Sheriff's officials say a Wisconsin man died after his boat capsized with two other passengers in Minnesota's Lake Superior.

The St. Louis County Sheriff's Office says 68-year-old Donald James Sarter was the operator of a 21-foot Monark aluminum-hulled boat that capsized at about 11 a.m. Monday when the engine became waterlogged. One of Sarter's passengers says they all had life jackets on but they were unzipped in front.

Rescue crews found Sarter, of Sturgeon Bay, Wisconsin, in shallow water and lifesaving efforts were unsuccessful. Sarter's passengers were able to swim to shore.
