(Associated Press) Hundreds of law enforcement personnel have begun an eighth day, Saturday, June 13, searching for two killers who used power tools to cut their way out of a prison in far upstate New York.

The searched continued Saturday the morning after a prison worker pleaded not guilty in Plattsburgh to giving contraband to inmates David Sweat and Richard Matt at the Clinton Correctional Facility in Dannemora.

Prosecutors say prison tailor shop instructor Joyce Mitchell befriended the men and gave them hacksaw blades, chisels, a punch and a screwdriver bit.

Mitchell is also suspected of agreeing to be a getaway driver but didn’t show up, leaving the men on foot early on June 6.

Mitchell’s hands were cuffed in front of her and she stared straight ahead while she was arraigned Friday night in Plattsburgh on charges of felony promoting prison contraband and misdemeanor criminal facilitation. She was ordered jailed on $100,000 cash bail.

Mitchell’s family has said she would not have helped the convicts break out. She pleaded not guilty.

Mitchell has another court appearance scheduled for Monday.

Police say they won’t stop looking for the escaped inmates.
