These inmates have some serious planning skills.

Daily Mail – Two convicted murderers escaped from a maximum-security prison in upstate New York sometime between Friday night and Saturday morning, authorities said.

Richard Matt, 48, and David Sweat, 34, performed a Shawshank Redemption-style escape from the the Clinton Correctional Facility in Dannemora, New York, by using power tools to cut through a steel wall in their cells.

The hole in the wall led the men to a series of tunnels, which took them to a manhole outside prison walls, police said.

The men even left a note on one of the tunnels reading, ‘Have a nice day’, accompanied with a smiley face, for authorities to later find.

It was discovered that the two were missing during the 5.30am inmate ‘standing count’, New York State Police said in a Facebook post. They had last been seen at the 10.30pm standing count the night before.
