One of the Clinton Correctional Facility escapees has detailed how he and his partner worked on their escape from prison over the course of months.

Officials tell the New York Times that Sweat has given a thorough account of his actions, which involved climbing through a panel he sawed off in his cell and exploring the tunnels underneath the prison for weaknesses in the structure nearly every night since last winter.

He was confident that guards wouldn’t notice he was missing during these missions because they were asleep. He had apparently been mulling this plan for some time, but took action only after being transferred to a cell next to Richard Matt, his partner in crime who was shot to death by a federal agent during the search for the escaped men.

Sweat says he and Matt joked about the similarity of their mission to the plot from the movie The Shawshank Redemption.
