Joyce Mitchell, who helped two convicted murderers escape an upstate New York prison in June, is headed to prison herself, as the judge said he didn’t find her explanation credible.

As tears streamed down Mitchell’s face, Judge Kevin Ryan sentenced the 51-year-old former prison worker to up to seven years for first-degree promoting prison contraband, a felony, and a concurrent year for fourth-degree misdemeanor criminal facilitation.

Mitchell also must pay $6,375 in fines, court fees and surcharges, and has a November 6 hearing set to battle the state’s demand for $119,762 in restitution for costs associated with the sensational June prison break by inmates Richard Matt and David Sweat.
