(CNN) --- DNA from New York prison escapees Richard Matt and David Sweat has been found inside a burglarized cabin in upstate New York, a law enforcement source told CNN.

The discovery has re-energized the two-week-old search for the convicted killers, who staged an escape from Clinton Correctional Facility on June 6 worthy of a movie script and haven't been seen since -- at least not by authorities.

However, a witness on Saturday spotted someone running into the woods near a cabin in the Mountain View community, only 25 to 30 miles from the prison, according to acting Franklin County District Attorney Glenn MacNeill.
