Accused sex trafficker Jeffrey Epstein was reportedly upbeat during his final meeting with his lawyers before his death, the New York Post reports.

Epstein, 66, was found unresponsive in his cell at the Metropolitan Correctional Center in Manhattan at about 6:30 a.m. on Saturday morning, and later pronounced dead at a hospital. The reported claims that Epstein died of a suicide by hanging have come under fire as more information is revealed about apparent irregularities at the federal jail that allowed Epstein, who had been placed on suicide watch weeks earlier, to remain unsupervised in a cell in a special housing unit in the immediate hours before he was found unresponsive.

“Every day he was very positive and the night before he was real positive,” a source said. “He was in great spirits the night before.”

Another unidentified source familiar with Epstein’s case reportedly told the New York Post that Epstein had claimed his previous cell mate, Nicholas Tartaglione, a former Westchester police officer accused of quadruple homicide, had caused the injuries that led to reports that Epstein tried to commit suicide.

Epstein reportedly said “the cop roughed him up, and that’s why they got him off suicide watch,” the source told the New York Post.

Tartaglione’s lawyer, Bruce Barket, told the newspaper that he did not believe his client had done anything to Epstein, and that Epstein’s lawyers never mentioned the claims to him.

“I do know that Nick was not brought up on any charges at all in the institution, so they cleared him,” Barket said, adding the Epstein “must have said something” to be removed from suicide watch only six days after the reported attempt.

Barket did not immediately respond to a request for comment from CrimeOnline.

The source who spoke to the New York Post about Epstein’s final meetings with his lawyers described the convicted pedophile as “delusional” about his chances of being federal sex trafficking charges.

“He thought he was going to win the double-jeopardy motion,” the source said, referring to state charges filed in Florida over a decade ago that led to a sweetheart plea deal, in which Epstein pleaded guilty to lesser charges and was sentenced to 18 months in prison with a provision for work-release during the majority of that sentence.

“He thought he was going to get the same deal he got in Florida,” the source said.

The source also said that Epstein referenced a future meeting with his lawyers during his last interaction with them.

“He was like, ‘I’ll see you Sunday.”

As CrimeOnline previously reported, sources familiar with Epstein’s autopsy report have said that he had multiple fractures in his neck, a reveal that has further contributed to speculation about the true circumstances of Epstein’s death.
