Manhunt for Kentucky shooting suspect forces authorities to search rugged terrain: "It is like a jungle"

The search for the suspect in last weekend's Kentucky highway shooting has taken authorities into a massive, dense forest that's been compared to a jungle in the southeastern part of the state. The manhunt for Joseph Couch, 32, has been going on since Saturday, when authorities say he shot and wounded five people who were traveling on Interstate 75.

The shooting happened near London, Kentucky, a city of about 8,000 outside Daniel Boone National Forest, which has "some of the most rugged terrain west of the Appalachian Mountains," according to the U.S. Forest Service. The terrain includes "steep forested slopes, sandstone cliffs and narrow ravines," according to the agency.

"It is like a jungle," Kentucky State Police Master Trooper Scottie Pennington told reporters Monday, "and we have cliff beds, we have sinkholes, we have caves, we had culverts that go under the interstate. We have creeks and rivers and the dense brush. I mean, it's not something I can just take my dog for a natural walk through."
