MADISON, Wis. -

A man's body recovered from Lake Monona Wednesday is that of a Kaukauna man reported missing in January.

The Dane County Medical Examiner said the man is identified as 26-year-old Charles Geurts. The medical examiner's office said more results from an autopsy are needed before determining the cause of death, but there is no evidence to suggest criminal activity.

Guerts went missing while staying at a hotel near Lake Monona on Jan. 26. He was in Madison with co-workers for a trade show at the Alliant Energy Center.

A citizen spotted what he believed to be a body while using his personal side scan sonar on Tuesday, according to the Dane County Sheriff's Office.

Deputies said Rick Krueger was using his sonar on Lake Monona Tuesday when he discovered the possible body in about 33 feet of water. Krueger was familiar with the case of Charles Geurts.

The Dane County Sheriff's Office Dive Team recovered the body Wednesday at 10:30 a.m. about a quarter mile from Olin Park.

A news conference is scheduled for 10:30 a.m. regarding the case.
