The surveillance video taken from outside Jeffrey Epstein's jail cell on the day of his first apparent suicide attempt has been permanently deleted, federal prosecutors said. Epstein, the disgraced financier who was facing federal sex-trafficking charges, was found semiconscious in his cell at the Metropolitan Correctional Center, or MCC, in New York around 1:27 a.m. on July 23. But that video is now gone because MCC officials mistakenly saved video from a different floor of the federal detention facility. The FBI made the discovery last week while reviewing a copy of the video provided by MCC officials. "After reviewing the video, it appeared to the government that the footage contained on the preserved video was for the correct date and time, but captured a different tier than the one where [the cell housing Epstein and his cellmate] was located." The filing was made in a case involving Nicholas Tartaglione ... who was Epstein's cellmate on the day of the incident. The July incident was investigated as a possible suicide attempt, assault or ruse by Epstein to get himself transferred to a different facility. Tartaglione's attorney, as part of an effort to exonerate his client, asked the jail to preserve video from outside the cell. The MCC agreed, but "the MCC computer system listed a different, incorrect cell for Tartaglione," prosecutors said in the court filing. A backup video system was in place, but the requested video wasn't available because of unspecified "technical errors," the court filing says.
