The Wisconsin Department of Justice D-C-I is investigating a fatal shooting during a Chippewa County traffic stop last week. Investigators say 30-year-old Lance Stelzer was operating a moped in the Town of Goetz when he was pulled over. The situation escalated October 8th shortly after 7:00 p-m when Stelzer and Sergeant Martin Folczyk started fighting. The sergeant shot the man after Stelzer sprayed him with an unidentified substance. Stelzer was rushed to a nearby hospital, but he died before he got there. Sergeant Folczyk is on administrative leave while the Division of Criminal Investigation examines the case.
