TOWN OF BERN, WI (WTAQ) - Marathon County deputies say a 3-year-old boy was killed when he was run over by a skid steer loader. The accident happened Friday in the Town of Bern. The farm equipment was being driven by the victim’s 7-year-old brother. A spokesman for the Sheriff’s Department says the 7-year-old was thought to have been giving three siblings a ride in the bucket when the younger boy fell out. The victim was dead at the scene. Authorities say they are still investigating, but they don’t expect to file charges in the accident. Neighbors tell broadcast reporters five families work on that Wisconsin farm.
