A Letcher County man was killed the morning of Tuesday, August 22, after the vehicle he was driving collided with a commercial tractor trailer. Kentucky State Police Post 12 received a 911 call advising of the crash just before 7:30am. Emergency personnel responded to the scene on Highway 15 in the Isom community of Letcher County. The preliminary investigation indicates that Ethan Adams, 19, of Whitesburg, was driving southbound on Highway 15 in a 2007 Chevrolet pick-up truck. The truck crossed into the northbound lane and collided with a 2006 Peterbilt tractor trailer operated by Johnny Caudill of Whitesburg. The Peterbilt overturned as a result of the impact while the pick-up came to rest in the southbound lane of the roadway. Johnny Caudill was flown to Pikeville Medical Center for treatment of injuries sustained in the collision. Ethan Adams was pronounced deceased at the scene by Letcher County Coroner Renee Campbell. An autopsy will be performed on Adams at the State Medical Examiner’s Office in Frankfort, and toxicology results are pending on both drivers.
