A manhunt is underway in New York after two convicted murderers escaped from a maximum-security prison. The prisoners used power tools to drill through the walls and break out of the Clinton Correctional Facility in Dannemora. Charles Guess of the New York State Police said the pair may have had help.

Charles Guess: “We’re leaving no stone unturned. It’s been approximately 36 hours since these inmates escaped. They could be literally anywhere, although we have notified our partners in Canada, the ports of entry across the northern border, and certainly every law enforcement agency in the Northeast. They could be out of state, but they still could be holed up here in Dannemora. We do not know if they had access to a vehicle, but we presume that they may have had access to a vehicle, as well as they may have received assistance in their escape effort, if for no other reason at least outside the secure perimeter of this facility.”

It’s the first escape from Clinton’s maximum-security wing in its history. Governor Andrew Cuomo has declared the manhunt a “crisis situation.”
