(Hustisford) One person suffered life-threatening injuries after being ejected in a single-vehicle rollover crash Thursday in the Town of Hustisford. Dodge County Sheriff deputies responded to the scene on Elmwood Road near Longview Road around 5:30pm. The initial investigation showed that a Honda Pilot, driven by a 20-year-old female from Neosho, was travelling westbound on Elmwood Road. She lost control while swerving for a deer and entered the north side ditch causing the vehicle to rollover. A 20-year-old male passenger from Brookfield was ejected. The driver sustained non-life threatening injuries and was taken by ambulance to Aurora Summit Hospital. The passenger suffered life-threatening injuries and was transported by Flight for Life to the same hospital. Authorities say speed and not wearing a seatbelt are believed to be contributing factors in the crash which is being investigated by the Dodge County Sheriff’s Office and Wisconsin State Patrol. Names are being withheld pending notification of family. Assisting at the scene were Hustisford Fire/EMS, Mayville EMS, Watertown Fire/Paramedics, Flight for Life, Wisconsin State Patrol and DCERT.
