An initial DNA test on remains believed to be those of Joseph Couch, the suspect in the Interstate 75 shootings, was inconclusive, but an autopsy confirmed the cause of death was a self-inflicted gunshot wound, state officials said.
The soft tissue DNA test was “inconclusive due to extreme decomposition of the body,” and a further DNA test with material extracted from bone will be completed, the Kentucky Justice and Public Safety Cabinet said in a news release.
The remains were found in deep brush by a highway exit in Laurel County, which is where London is and where the shootings occurred, state officials said.
A couple livestreaming the search for Couch's body helped in the effort and the discovery, state police said.
The DNA test from bone is expected to begin Friday and take 24 to 48 hours, the Justice and Public Safety Cabinet said.
