DANNEMORA -- Hundreds of law enforcement officers are today focusing east of Danemora in their search for the two convicted murderers who last weekend used power tools to escape from Clinton Correctional Facility.

The ground search for inmates Richard Matt and David Sweat is concentrated on a heavily wooded area off state Route 374, east of Dannemora and west of Plattsburgh. Search teams are following up on a lead developed late Wednesday, according to state police.

Thursday's search involves more than 500 law enforcement personnel, along with K9 and aviation units. The FBI, U.S. Marshals, U.S. Customs and Border Protection, officers from the Department of Corrections and Community Supervision, Department of Environmental Conservation, Forest Rangers, Clinton and Essex County sheriff departments and the Plattsburgh Police Department are assisting troopers.

Route 374 remains closed between General Leroy Manor Road and Rand Hill Road in the town of Plattsburgh. The road will remain closed during this search, troopers said. In addition, residents in the area can expect to see an increased police presence throughout the day.

Troopers say the public should not hesitate to report any suspicious activity. That includes any sign of a trespass, burglary or vehicle larceny. People can call 911, a local law enforcement agency, or the New York State Police to report any information related to the investigation at (518) 563-3761 or 1-800-GIVETIP. Tips can also be sent by email to crimetip@troopers.ny.gov.

State police say they thank local residents and businesses for their patience and cooperation during this search.
