Wednesday night at approximately 7:51 p.m. CDT the Tell City Dispatch Center received a 911 call reporting a crash on I-64 at mile post 73.5 westbound. Initial information reveals that Kenneth G. Derr, 64, Boonville and his brother Michael W. Derr, 69, Evansville had pulled off onto the north shoulder to change a flat tire on their trailer. The flat tire was on the left (driver's) side of the trailer. Kenneth was in the process of changing the tire when a dark colored, believed to be an older model dark blue small pick-up truck or passenger car crossed over the fog line and hit Kenneth. Then without stopping the suspect vehicle continued west on I-64. Kenneth was pronounced dead at the scene by the Perry County Coroner's Office. An autopsy is scheduled for Thursday in Tell City. Michael was not injured. The Derr's vehicle, a black 1996 Jeep Cherokee and the trailer they were pulling were not damaged. The suspect vehicle has not been located and should have damage to the front right (passenger's) side.
