Officials are saying they are working to confirm the identity of a body that has just been found in Laurel County. Kentucky State Police shared a post on social media on Wednesday saying a body was found “in the vicinity of exit 49 in Laurel County, and detectives are working to confirm the identity.” Exit 49 is on I-75, the same location where five people and nearly a dozen vehicles were shot on Saturday, Sept. 7.

Since then, a large manhunt has been underway for the alleged shooter, Joseph Couch. It has not been confirmed that the body found is Couch. However, the update comes just one day after Governor Andy Beshear, Kentucky State Police, and state officials announced they would be shifting resources out of Daniel Boone National Forest in Laurel County and into the community.

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.

Couch, 32, a former Army reservist, had been the subject of a manhunt after five people were shot and seriously wounded as they drove on Interstate 75 north of the small city of London on Sept. 7.At least 12 vehicles were struck, and 20 to 30 rounds are thought to have been fired, officials said. 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.

“At this time, we are able to confirm that the autopsy revealed the cause of death to be a wound consistent with a self-inflicted gunshot to the head,” the state chief medical examiner, Dr. William Ralston, said in a statement. The DNA test from bone is expected to begin Friday and take 24 to 48 hours, the Justice and Public Safety Cabinet said.
