New York Gov. Andrew Cuomo (KWOH'-moh) 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.
