New York Gov. Andrew Cuomo says investigators are looking into whether civilian employees or private contractors helped two murderers obtain the power tools the killers used to break out of a maximum-security state prison near the Canadian border.
Cuomo said during a round of appearances on television morning news shows Monday that he'd be "shocked" if a prison guard was involved in the escape from Clinton Correctional Facility in Dannemora, 20 miles south of the border.
Officials say 34-year-old David Sweat and 48-year-old Richard Matt cut through steel pipes and walls while making their escape, which guards discovered early Saturday. They are still on the loose.
Cuomo says investigators are interviewing hundreds of civilian prison employees and the contractors who have been doing extensive renovations at the 150-year-old facility.

The brother of a man killed by one of two murderers who escaped from a maximum-security prison says the prison break has turned his world "upside-down all over again."
Steven Tarsia tells The Associated Press he couldn't believe it when he found out David Sweat and fellow inmate Richard Matt broke out of an upstate New York prison.
Sweat was convicted of first-degree murder for killing Sheriff's Deputy Kevin Tarsia in 2002.
The inmates used power tools to cut their way to freedom and emerge from a manhole cover blocks from the prison. They were reported missing from their beds at about 5:30 a.m. Saturday.
Authorities are investigating how they could have gotten the tools.
Steven Tarsia says he thinks they must have had help, but can't imagine why anyone would have helped them.

New York's governor says two convicted murderers "had to be heard" as they cut through steel and escaped from a maximum-security prison.
Gov. Andrew Cuomo told ABC's "Good Morning America" that Richard Matt and David Sweat broke out of the Clinton Correctional Facility in "a really elaborate, sophisticated operation" that involved shimmying through a steam pipe.
The men were reported missing from their beds at about 5:30 a.m. Saturday.
Roadblocks were set up in the area of the prison, about 20 miles from the Canadian border. Bloodhounds and helicopters were being used to track down the men.
Cuomo said officials were reaching out to the families of the men's victims.

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.
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.
