Video footage of the area around Jeffrey Epstein's jail cell on a day he survived an apparent suicide attempt "no longer exists," federal prosecutors told a judge.

Officials at the Metropolitan Correctional Center in New York believed they had preserved footage of guards finding Epstein after he appeared to have attempted suicide, but actually saved a video from a different part of the jail, prosecutors said.

The FBI also has determined that the footage does not exist on the jail's backup video system "as a result of technical errors," Assistant U.S. Attorneys Maurene Comey and Jason Swergold wrote in a court filing.
