David Sweat, one of the inmates who escaped from Clinton Correctional Facility in June 2015, is no longer being housed at Five Points Correctional Facility in Seneca County. 

The state Department of Corrections and Community Supervision said Sweat has been transferred from Five Points to Attica Correctional Facility, a maximum security prison in Wyoming County. He was moved on Nov. 17, according to the agency. 

"Based on biannual reviews, which include looking at concerns like an inmate's behavior, allegiances with other inmates that could become disruptive or over-familiarity with a facility, there are approximately 5,000 inmate transfers from one prison to another every month," said DOCCS spokesman Thomas Mailey, who confirmed Sweat's transfer. 

Sweat, who was serving a life sentence for murdering a Broome County deputy sheriff, and Richard Matt, another convicted murderer, escaped from Clinton Correctional Facility on June 6, 2015. An investigation revealed that the pair used hand tools to escape and were aided by a prison employee, Joyce Mitchell. 

Matt and Sweat eluded authorities for three weeks. On June 26, 2015, Matt was shot and killed by a Border Patrol agent. Two days after Matt's death, Sweat was wounded and arrested by a state trooper. 

Sweat spent nearly a week in an Albany hospital before he was moved to Five Points Correctional Facility in Romulus. He pleaded guilty in November 2015 to two counts of first-degree escape and one count of promoting prison contraband. 

While at Five Points, Sweat was held in the prison's Special Housing Unit, which is commonly referred to as solitary confinement. His living arrangements haven't changed at Attica. He is being held in the Special Housing Unit.
