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.

Authorities say a body has been found near the Kentucky site where a gunman opened fire on an interstate highway, hitting a dozen vehicles and wounding five people.
