Hundreds of law enforcement officers have spent the night searching for two convicted murderers who escaped a maximum-security New York state prison.
Officials say Sunday officers from local, state and federal agencies are seeking 48-year-old Richard Matt and 34-year-old David Sweat.
Gov. Andrew Cuomo says the duo used power tools to cut through steel pipes at the Clinton Correctional Facility near the Canadian border.
They were discovered missing at about 5:30 a.m. Saturday morning.
Cuomo says their escape was the result of "an elaborate plot."
Sweat was serving a life sentence without parole for killing a sheriff's deputy in 2002. Matt was sentenced to 25-years-to-life for the kidnapping, dismemberment and murder of his former boss in 1997.
