A New York prison employee accused of helping two murderers break out by smuggling in tools is due in court.

Joyce Mitchell, who was a tailor shop instructor at Clinton Correctional Facility, was jailed shortly after Richard Matt and David Sweat escaped on June 6. Matt was shot and killed three weeks later. Sweat was captured and sent to another prison.

Mitchell is accused of providing hacksaw blades, chisels, a punch tool and a screwdriver to Matt. Authorities say she agreed to be their getaway driver but backed out at the last moment.

Clinton County District Attorney Andrew Wylie says Mitchell will be arraigned Tuesday morning. Her lawyer has said he hopes for a plea agreement.

The 51-year-old northern New York resident pleaded not guilty after her arrest.
