It took nearly a year, but the body found in Okauchee Lake last October has been identified as a man who was last seen in 1996. Thomas Engel was reported missing after a boating accident on the lake 21 years ago. He was 31 years old at the time. Oconomowoc Police Chief James Wallis remembered the cold case and he tracked down family member to get a D-N-A sample. It took 11 months to get the test results back and confirm the identity.
