According to Lewis Kasman, former top mob confidant to John Gotti, in regards to Epstein's suicide:

“If he killed himself someone had to have helped him,” said Lewis Kasman, a onetime close confidant of the Dapper Don who visited the godfather several times at the Metropolitan Correctional Center in 1992. There are cameras going 24/7 and they’re watching 24/7. Someone had to give [Epstein] the equipment to kill himself and he had to pay for it dearly,” said Kasman, who has kept abreast of conditions in the lockup. Kasman added: “That facility for years had issues of corruption, with correction officers bringing in food or cellphones for wealthy people.”

AND from Kasman:

"Kasman said he heard US Attorney General William Barr personally made a hush-hush trip to the MCC two weeks ago, about the time Epstein was found in his cell with bruises around his neck. “When does that happen?” he asked. “The attorney general never visits jails. Something’s not right there.”
