The search for a missing Kewaunee boater has officially ended, but authorities are asking that the public be aware and report any suspicious objects they may see in the waters of Lake Michigan.

The Kewaunee County Sheriff’s Department received a call at 10:49 p.m. July 4 for a missing boater who had gone fishing out of Kewaunee Harbor.

The operator of the boat in this incident has been identified as Mark A. Wautelet, 38, of Kewaunee.

The United States Coast Guard, County Rescue of Brown County and the Wisconsin Department of Natural Resources have assisted the Sheriff’s Department in the search.

“While initial efforts focused on rescue operations, those operations have since been concluded with the focus transitioning to sub-surface recovery operations,” Sheriff Matt Joski said in an update Monday. “Currently the Department of Natural Resources will continue to conduct sub-surface sonar scanning when conditions allow and resources are available.

“The Kewaunee County Sheriff’s Department is asking that boaters be aware and report any suspicious objects they may observe while out on the waters of Lake Michigan. The boater in this incident was wearing a lime-green shirt with blue denim jeans along with a red-and-white Wisconsin Badgers base ball cap and brown crocs footwear.

“We appreciate all of the support and resources we have received thus far as well as those in the future to help bring closure to the victim’s family in this tragic incident,” Joski said.
