The manhunt widens for the convicted murderers who broke out of Clinton Correctional Facility in Dannemora, New York. State Police say they have received more than 15-hundred leads, although as of Friday, there have still been no confirmed sightings of escaped inmates Richard Matt and David Sweat, who sawed their way out of their cells and crawled through a steam pipe to their freedom. New York Governor Andrew Cuomo has called for an investigation into how the two were able to carry out the elaborate plot, and whether they received assistance from inside or outside the prison. The intense manhunt in an area east of the prison has been scaled back after a several-day search turned up no sign of the escapees. State Police say 600 officers are now canvassing trails and railroad beds, and searching remote homes and camps in the Adirondacks for the two.
