An initial DNA test on remains believed to be that of alleged I-75 shooter Joseph Couch was inconclusive, but a self-inflicted gunshot was the cause of death.

Human remains found in Kentucky have been positively identified as the man who shot 12 vehicles and wounded five people on Interstate 75 more than a week earlier.

Authorities in Kentucky called off the manhunt for the suspect they believe was responsible for a mass shooting on a remote stretch of highway after they located a body deep in the woods—with the help of a pair of YouTubers.
