The upstate prison worker accused of aiding two inmates in their daring escape from Clinton Correctional was apparently investigated for a "sexual incident" with one of them a few months ago.

Joyce Mitchell, 51, appeared in court briefly today. She pleaded not guilty to all charges, including promoting prison contraband and criminal facilitation, and also got a new lawyer because her old lawyer had a conflict of interest. Mitchell allegedly gave hacksaw blades, drill bits and eyeglasses with lights affixed to them to Richard Matt, 48, and David Sweat, 34, who orchestrated an elaborate escape through the maximum security prison's infrastructure and eventually the sewer system, exiting via a manhole on the other side of Clinton Correctional.

The NY Times reports, "Looking blank and pale and wearing a black-and-white-striped jail uniform, Ms. Mitchell spoke only when the judge, Mark J. Rogers, asked if she understood the change of lawyers. 'Yes,' she answered in a soft voice, nodding. Her new lawyer is Stephen Johnston. He declined to comment after the hearing, saying he had not spent enough time with his client."

Matt was serving a 25 year-to-life sentence for killing and dismembering his employer, while Sweat was serving a life term for killing a Broome County sheriff's deputy. Both men had very troubled upbringings.

According to NBC News, Mitchell was "investigated after a sexual incident with David Sweat in the months before Sweat and Richard Matt broke out of Clinton Correctional Facility in Dannemora, New York, sources say. While she was being investigated for the incident, Matt allegedly charmed Mitchell into his affection." Matt is reportedly very charismatic and well-endowed, in addition to being violent and volatile.

Mitchell was allegedly going to pick up Sweat and Matt from the manhole, but supposedly got "cold feet" and decided not to go through with it. She also allegedly had planned on having the escapees kill her husband.

The manhunt for Matt and Sweat is still in full force: The Times-Union reports, "Law enforcement officers were concentrated along a wooded area three to five miles east of Dannemora along routes 374 and 3 in Cadyville, a hamlet of Plattsburgh, where they have been looking since Wednesday night... More than 800 law enforcement officers are scouring the area for the men." Clinton County District Attorney Andrew Wylie said, "We're still doing the push on the manhunt. We're trying to exhaust that and confirm whether or not they're still there."

Wylie was also told that the manhunt is costing about $1 million a day, though Governor Cuomo's office hasn't confirmed it. What Cuomo has done is call for the Inspector General to investigate the prison break, "Capturing these killers and returning them to state custody remains our top priority - however, it's critically important to examine the circumstances that enabled these inmates to escape in the first place."

Of course, now funding cuts to prisons are being examined—cue Cuomo blame—while the manhunt itself is "hampered by State Police secrecy, inter-agency rivalries, and the disrupting involvement of Gov. Andrew Cuomo on the first day of the breakout, law enforcement sources have told The Post."
