I think there may be some confusion here. Barr did state his conclusion that Epstein's death was suicide, enabled by a series of "screw-ups" like malfunctioning cameras, the transfer of his cellmate, etc. There was also a false conspiracy theory that Barr had secretly visited Epstein in his cell prior to Epstein's death, suggesting that Barr might have ordered Epstein's murder. There was no such visit.
