PORTAGE, Ind. (AP) — Authorities say an Ohio man has died after going missing while swimming at a Lake Michigan beach along northwestern Indiana.

The Indiana Department of Natural Resources says Salomon C. Martinez of Cincinnati was swimming with a group of friends Sunday at Portage Lakefront Riverwalk beach in Portage when he didn’t resurface. Fire department rescuers found him underwater.

The DNR says Martinez was taken to a hospital and died.

Assistant Portage Fire Chief Tim Sosby tells The (Northwest Indiana) Times that the lake surface was choppy at the time due to winds. Sosby says that there has been a higher than average number of calls to assist people on Lake Michigan this season.

GRAND HAVEN, Mich. (AP) — Authorities say people formed human chains along the shores of Lake Michigan to rescue swimmers caught in rough water blamed for two drownings over the weekend.

Officials in western Michigan say three other people were hospitalized after being pulled from the lake Sunday.

The Grand Haven Department of Public Safety says beachgoers used a human chain to reach a 64-year-old man experiencing trouble in the “hazardous wave conditions” around noon.

Jeff Hawke, director of public safety, says the man was transported to a local hospital, where he was pronounced dead.

Nearly four hours later, the department says a 20-year-old man from Lansing was pulled from the water. The unidentified man also died.

Hawke says three other people were hospitalized after being rescued, including a 46-year-old man in serious condition.
