Knox County Sheriff Mike Smith says deputies found meth, heroin and fentanyl during an arrest. Deputies say 54-year-old John Carr was in the parking lot of a business known to be a high drug trafficking area. Carr also had warrants for manslaughter and DUI. As deputies took him into custody, a K-9 with the Corbin Police Department alerted Carr’s truck. During a search of the truck, deputies found a large amount of meth, heroin, fentanyl, two sets of digital scales, baggies and a long rifle. Carr was lodged in the Knox County Detention Center.
