The first major lead into the whereabouts of escaped murderers Richard Matt and David Sweat came with the discovery of prison-issue underwear in a remote hunting cabin in upstate New York. As the manhunt for the two escapees reached a 17th day on Monday, DNA matching the killers -- and the discarded underwear -- were found in a cabin in Franklin County, an unnamed official told The New York Times Monday. The cabin, near the hamlet of Owls Head, is roughly 20 miles west of the Clinton Correctional Facility in Dannemora, where Sweat and Matt escaped June 6.
