LAKE GENEVA, Wis. (CBS 58) -- Geneva Lake police have identified the man who drowned in Lake Geneva Monday as 40-year-old David Trehane of Chicago, Illinois.

Police say as Trehane was swimming in the water, the pontoon boat he had been on began drifting. He called for help, but the other individuals on the boat were unable to get the boat started. They threw a life jacket at him, but he was unable to retrieve it.

The individuals on the boat immediately called 911 and police, fire and rescue responded to search for Trehane. 

The initial response was a rescue, but turned into a recovery operation.

Police say the investigation is continuing, but no criminal charges are expected.

LAKE GENEVA, Wis. (CBS 58) -- Police say they have recovered the body of a swimmer who went missing in Lake Geneva Monday evening, July 27.


A 41-year-old man went missing in Lake Geneva around 5 p.m. Monday, and rescue crews searched for him until dark without any luck.

Crews started the search again Tuesday morning at 7 a.m., and the man's body was recovered by a dive rescue team.

Police say the man rented a pontoon boat and was swimming with two other people when he began to struggle in the water.

The two other people were able to get back in the boat. The water is 14-feet deep in the area where the man was struggling.

Police don't believe foul play was involved or that drinking was a factor.

Witnesses say it was a scary situation.

"I started hearing sirens and so I was kind of getting concerned, so I kind of just went up and rode my skateboard and kind of road a little bit trying to make it back where I was staying and just like more police cars, ambulances, sirens and everything was kind of getting a little eerie," said Katelyn Keefe.

Police say they will give more updates at a later time. 

They have not released the man's name at this point.
