Federal prosecutors have found surveillance video of the area around the cell of accused child sex trafficker Jeffrey Epstein on the day of his first jailhouse suicide attempt, according to a new court filing. Earlier this week, they said the footage was missing.

The video, which prosecutors said was actually preserved by jail staff as previously requested, was being sought by lawyers for Epstein's former cellmate at the Metropolitan Correctional Center in Manhattan.

That cellmate, former Westchester County, New York, police officer Nicholas Tartaglione, claims he helped save the life of the wealthy investor Epstein during his suicide bid at the federal jail on July 23.

Epstein, 66, died weeks later in from what authorities have ruled was a suicide by hanging in that jail, where the former friend of Presidents Donald Trump and Bill Clinton was awaiting trial on charges related to his alleged sexual abuse of dozens of underage girls from 2002 through 2005.

His death, which remains under investigation, sparked conspiracy theories that he actually was murdered because of his ties to wealthy and powerful people, some of whom have been accused of having sex with Epstein's victims. Neither Trump nor Clinton have been accused of having sex with women connected to Epstein.

Prosecutors have charged two guards with trying to cover up their alleged failure to conduct mandated safety checks on Epstein and other inmates in the hours before he was found unresponsive in the cell.

Video surveillance from the hours before Epstein was found lifeless on Aug. 10 shows that no one entered his cell after he entered it the night before.

At the time of his death, Epstein did not have a cellmate.

But Tartaglione was in the cell on July 23, when Epstein is believed to have first tried to kill himself, and when jail staff found him semiconscious on the floor of the cell, with marks on his neck.

Tartaglione is being held in the jail without bail on charges related to the drug-connected murders of four people.
