FRANKFORT, Ky. (WKYT) - The body found near the scene of the I-75 mass shooting has been identified.

According to a release from Gov. Andy Beshear’s Office, the body has been positively identified as Joseph Couch through DNA extracted from bone.

Couch is the suspect accused of shooting five people Sept. 7 on Interstate Highway 75 in Laurel County. His body was found near Exit 49 Wednesday afternoon.

Previous results were inconclusive based on a soft tissue DNA test.

“Due to extreme decomposition of the body, the soft tissue DNA test was inconclusive, but today we were able use bone from the suspect to get a positive identification,” said Kentucky’s Chief Medical Examiner Dr. William Ralsto. “I want to recognize the medical examiner’s office and KSP crime lab for working together and being diligent in obtaining positive identification so the commonwealth can move forward from this tragic situation.”

Ralston released the cause of death as a wound consistent with a self-inflicted gunshot to the head. The official autopsy report will not be available for release until toxicology results return.
