Nels Gunderson, owner of I-94 Towing and Recovery in Osseo, said he has seen it all in his 44 years operating a towing service and serving on the Osseo Fire Department for 42 years, including the deaths of emergency responders trying to lend aid at accident scenes. It was because of the frightening and tragic stories Gunderson and other emergency responders can tell that they gathered at the Chippewa Valley Technical College Emergency Service Education Center on Nov. 13 in recognition of Traffic Incident Response Week to send the public a message: Move over. It’s the law and their lives depend on the public obeying. Gunderson was there when Trooper William Schoenberger was killed while blocking traffic during a car fire response in 1993. Gunderson’s service was there when Trooper Deb McMenamin was killed in 1980. And Gunderson has seen many secondary accidents involving civilians during accident responses.
