Mitchell pleads guilty to helping two convicted murderers escape from a maximum security prison last month. She allegedly provided tools to Matt before the escape by concealing them in hamburger meat. She pleads guilty to first-degree promoting prison contraband and fourth-degree criminal facilitation. She faces a prison sentence ranging from 2 1/3 years to 7 years. She also agrees to cooperate with the investigation and give up her teaching certificate. The judge says Mitchell, who wiped away tears while making the plea, could be released on $100,000 cash or $200,000 bond. Mitchell will be sentenced on Sept. 28.
