TOMAHAWK (WRN) - The state DNR is investigating a snowmobile crash in north central Wisconsin that killed an Oxford man. 22-year-old William Titschler died at a hospital in Tomahawk. The crash was reported early Sunday morning near Tomahawk in the Lincoln County town of Bradley. Authorities said Titschler’s snowmobile left a roadway and hit a tree. Officials said excessive speed and alcohol might have been factors. Titschler is at least the 4th person to die in a Wisconsin snowmobile crash this winter – the same number as a year ago at this time. As of last Monday, the DNR had reported 3 deaths this season in Oconto, Oneida, and Crawford counties. There were 23 snowmobile deaths statewide last winter.
