He used her until he had no more use for her.
Escaped killer Richard Matt won the heart of prison supervisor Joyce “Tillie’’ Mitchell so he could get the tools he needed to break out — and then vanished without so much as a thank you, sources told The Post on Tuesday.
“She really doesn’t have much to tell about where they were going or what they were doing after,” a source said of Mitchell, who is suspected of helping Matt and fellow murderer David Sweat escape.
The married 51-year-old seamstress risked everything because “she thought there was something more between’’ her and Matt, 48, the source said.
“He’s a con man,’’ the source said of Matt.
“He’s a con man,’’ the source said of Matt.
Authorities believe that the smooth-talking con, who has brooding good looks — and steel front teeth — convinced Mitchell to help the men escape.
The unlikely pair met in the tailor shop at the Clinton Correctional Facility, where Mitchell supervised inmates on projects. Matt and Sweat had been assigned to the shop as a perk for behaving behind bars.
Mitchell and Matt share interests that include the US military. She posted a photo on Facebook in March 2014 of herself with her son in his Air Force uniform. She was wearing a red shirt that read, “AIR FORCE Mom, I raised a hero.’’
Matt, meanwhile, sports a large tattoo of the US Marines insignia on his right shoulder.
Mitchell’s son, Tobey, doesn’t believe his mom’s involvement.
“She’s not going to risk her life or other people’s lives to help these guys escape,” he told NBC. “She’s always been a good person.”
Her husband, Lyle Mitchell, also works as a prison supervisor at Clinton. Authorities believe he had no idea what his wife was up to, sources told The Post.
Joyce Mitchell, a former tax collector in the family’s home town of Dickinson, was clearly proud of her prison work. In a 2013 Facebook posting she wrote, “It takes balls to work behind the walls. No guns . . . just pure guts.”
