It’s been three years since inmates Richard Matt and David Sweat escaped from Clinton Correctional Facility in Dannemora. The prison break set off a three-week manhunt. Matt was killed in a shootout, Sweat was shot and arrested.

In the months that followed there were crackdowns and investigations, some highly critical reports about corrections practices and personnel. Corrections officials say they have worked to improve security at prisons statewide. But a new report from State Inspector General, Catherine Leahy Scott, found ongoing security lapses that continued at least through last year.
