LINDLEY, N.Y. (AP) — New York State Police are investigating a possible sighting of the two convicted killers who escaped from an upstate New York prison two weeks ago.

In a news release posted late Friday, State Police say two men fitting the description of inmates David Sweat and Richard Matt were seen a week ago in Steuben County, New York, over 300 miles southwest of the prison in Dannemora. Two men were seen walking near a rail yard in Erwin on June 13, and then seen the next day in Lindley, New York, heading toward the Pennsylvania border.

Investigators conducted interviews and have surveillance video that is being sent to Albany for analysis.

Sweat and Matt used power tools to cut their way out of Clinton Correctional Facility on June 6.

Meanwhile, a correction officer has been placed on administrative leave as part of the investigation. The state Department of Corrections and Community Supervision says no additional information is available.
