When a gunman perched atop a cliff’s ledge opened fire on a dozen cars on Kentucky’s Interstate 75, wounding five people, it permeated surrounding communities with fear – and sent one couple into the woods to join the dayslong manhunt for the assailant.

The couple called themselves “bounty hunters on the hunt.” A day before they found the body of 32-year-old Joseph Couch, who opened fire Sept. 7 on a busy stretch of interstate near Exit 49, about nine miles north of London, the couple told Kentucky state troopers their goal: get Couch off the streets and collect the reward money.

Investigators believe they have found the body of a man they say shot five people and a dozen cars on an interstate highway in Kentucky this month, state police said Wednesday – ending an 11-day manhunt that stretched deep into the sprawling Daniel Boone National Forest and put surrounding communities on edge.

Fred and Sheila McCoy say a "date night idea" turned into a multi-day bounty hunt for wanted man Joseph Couch.

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.
