A skater died on Sunday afternoon after falling through thin ice on Plymouth's Medicine Lake.
The man was found in the water about 3 p.m. after another skater spotted a hat floating in the water and called police at 1:50 p.m., the Hennepin County Sheriff's Water Patrol reported.
When pulled from the water, the man had no pulse and was not responsive to resuscitation attempts. He was rushed to North Memorial Medical Center in Robbinsdale.
Water Patrol personnel found him about 600 yards from shore, said Sgt. Chris Mathisen of the Sheriff's Office.
The man was wearing ice skates and had a camera around his neck, Mathisen said.
The victim, who authorities believe was visiting from out of town, has not been identified pending notification of relatives.
The area where he was skating, near French Regional Park off Rockford Road, had been open water on Saturday and froze overnight, Mathisen said.
Sunday's snowfall probably made it appear thicker and safer than it was. "That's what we're guessing," Mathisen said. "He just got into a bad area. There's a lot of open water."
He said ice fishermen on the lake Sunday reported the ice in their area as 4 to 6 inches thick.
The Plymouth Fire Department also responded to the call.
