Clinton County District Attorney Andrew Wylie scheduled a press conference for noon Wednesday for updates on the investigation.
The search for Sweat, 35, and Matt, 48, expanded this week and shifted to other areas surrounding the village, State Police said.
More than 800 local, state and federal law enforcement officers had been concentrating on an area along Route 374 in Cadyville, a hamlet in the town of Plattsburgh, Clinton County, since June 10 attempting to locate the pair, who escaped from the maximum security prison June 6.
Joyce Mitchell, who allegedly helped the inmates escape from the maximum security prison, had her case transferred Monday to Clinton County Court. A future court date has not yet been set, according to the office of Stephen Johnston, Mitchell’s attorney.
On Tuesday afternoon, Mitchell was transported from the Clinton County jail back to the Rensselaer County lockup, where she also spent the weekend, Clinton County Sheriff David Favro said. With the contention surrounding Mitchell’s case and the ongoing media frenzy, Favro said it would be best for all involved to move her again.
Mitchell, 51, of Dickinson Center, Franklin County, was charged after allegedly providing hacksaw blades, chisels, a metal punch and a screwdriver drill bit to Matt and Sweat.
Wylie said that Mitchell could face more charges.
Law enforcement sources said Mitchell and one of the fugitives, possibly Matt, had developed an intimate relationship and that she planned to be their getaway driver when they emerged from a sewer manhole a block from the prison when they escaped.
While she was still jailed in Plattsburgh Tuesday she was visited by her husband, Lyle, a maintenance worker at the prison whom Mitchell had allegedly discussed killing with Matt and Sweat, a law enforcement source told the Times Union.
The source, who did not have direct knowledge of the interrogation, was told that during two State Police interviews lasting 10 hours each, Mitchell allegedly said the inmates may have planned to flee to a cabin at an undisclosed location in Vermont.
Favro said there was nothing unusual about Lyle Mitchell’s visit Tuesday, and nothing obvious to demonstrate he was angry with her. Lyle Mitchell was initially listed as a person of interest in the escape but has not been accused of wrongdoing.
