State police searching for two killers who escaped from an upstate New York prison two weeks ago say they're prepared to keep going for the "long haul."

Richard Matt and David Sweat cut their way out of Clinton Correctional Facility in Dannemora on June 6. Up to 800 officers have been searching for the escapees since then.

Police tell reporters Friday that the pair could be anywhere, but they are focusing their ground search in the heavily wooded region around the prison near the Canadian border. Investigators also are checking hundreds of leads.

State Police Maj. Charles Guess says police remain prepared for rapid response, but are used to investigations that last for months or years.
