(Oakfield) A Brownsville man suffered life-threatening injuries Thursday morning while hunting on DNR owned land. The Fond du Lac County Communications Center received a 911 call from Jonathan Henninger around 5:40am. Authorities were dispatched to the property west of County Highway Y south of the village of Oakfield. Henninger told authorities over the phone that he had tripped and fell on an arrow, sustaining a deep laceration to his upper arm. The 39-year-old was able to apply a makeshift tourniquet that slowed the bleeding. Fond du Lac County Sheriff Ryan Waldschmidt says emergency personnel utilized a UTV and pickup truck to navigate the land, then travelled the rest of the way on foot. Henninger was located more than six-tenths of a mile from a DNR parking lot and responders were able to treat and prepare the man for extrication. He was transported by ambulance to St. Agnes Hospital. Waldschmidt says, coincidentally, the public hunting land was the site of a joint training exercise conducted by the same emergency personnel earlier this year. He says that exercise trained first responders to navigate various locations throughout the property using GPS coordinates provided by the Communications Center. Waldschmidt says that exercise became a reality Thursday morning and helped save Henninger’s life. Responding agencies include the Fond du Lac County Sheriff’s Office, Oakfield First Responders, Oakfield Fire Department, a DNR Warden and LifeStar Ambulance.
