A search for Joseph Couch, the Kentucky man suspected of opening fire on vehicles on Interstate 75 and injuring five people, entered its fourth day Tuesday as officials scoured Daniel Boone National Forest using helicopters, drones and canines.

A manhunt is underway early Sunday as police searched for a gunman in a rural area of southeastern Kentucky who is believed to have shot and wounded five people near Interstate 75.

In Eastern Kentucky, you remember where you were when shots rang out on I-75. With the lone suspect still on the loose, it’s hard to forget.
