WAUSAU, Wis. (AP) The Wisconsin Department of Natural Resources is investigating four shootings involving deer hunters on opening day. A 40-year-old Edgar man was shot in the chest near the shoulder around 9 a.m. Saturday in the Marathon County town of Wien. Sheriff's Lt. Dale Wisnewski says the wound was not life threatening. The DNR says a deer drive was involved. The Wood County Sheriff's Department says about two hours earlier a hunter attempting to shoot a deer shot another hunter near Arpin. The Wausau Daily Herald reports that hunter was in serious condition Saturday. In Door County, a hunter was hit in the thigh and a hunter was grazed in Marquette County. The DNR says near ideal conditions across the state contributed to an active morning.
