Major manhunt as killers escape New York maximum security prison

A frantic manhunt was on Sunday for two convicted murderers who busted out of New York state's biggest maximum security prison by cutting through cell walls with power tools and escaping along tunnels. Killers Richard Matt, 48, and David Sweat, 34, sneaked out of the all-male Clinton Correctional Facility in Dannemora sometime between Friday night and early Saturday, with police saying the discovery was made during morning "roll call" and warning the duo should not be approached.
