Sheriff Millsap said the shotgun Norman is alleged to have used has not been located, according to KYTV.
"There was a tattoo that was still vaguely showing. We had a missing person from that week and we were able to figure out the tattoo may have belonged to [Young] and that’s how we really started with the investigation," Millsap told KYTV.
A friend of Young's told deputies they had seen Norman driving around town in Young's truck.
Deputies searched the truck and reportedly found a saw with no blade, as well as what appeared to be muscle, fat, hair follicles and blood, KYTV reports. DNA found on the saw in the truck matched Young's.
