State police spokesman Beau Duffy says officers got a lead that the prisoners might be in Allegany County, near the Pennsylvania border. David Sweat and Richard Matt escaped June 6 from the Clinton Correctional Facility in Dannemora, near the Canadian border. Yesterday, state police said in a news release that two men fitting the description of Sweat and Matt had been seen a week ago in Steuben County. Allegany County is west of Steuben County. Officials also said yesterday that a corrections officer was placed on administrative leave as part of the investigation into the men's escape.
