One person was killed and another seriously injured in a fiery crash in Jefferson County early yesterday morning. Sheriff Paul Milbrath says they received a call just before 1:30 reporting a fire near the intersection of Navan Road and River Bend Road in the Town of Milford. Once on scene deputies found a pick-up truck fully engulfed in flames. While checking the area, authorities found a boy who had been ejected from the vehicle. He was taken by Med-Flight to UW-Hospital in Madison with serious leg injuries. After putting the fire out a second person was found dead inside the vehicle. Milbrath says the crash is still under investigation.
