2/10/12 – Authorities are investigating the cause of a fire in Randolph that destroyed the home of a former Columbia County sheriff’s deputy. A short time after the fire, 38-year-old David Sadowski was found just over the Dodge County line, dead in his pick-up truck from an apparent self-inflicted gunshot wound. The home is located on County Highway G, two miles west of State Highway 73 and the fire was reported yesterday morning just after 3am. A press release from the Columbia County Sheriffs Department said a “citizen” called in the fire. Sadowski served eleven years in Columbia County but recently left the force. The fire is under investigation by the Dodge County Sheriffs and Medical Examiner’s Office. Dodge County is also heading the death investigation along with the state Justice Department.
