A Minnesota man allegedly tried to break Luigi Mangione out of his New York jail by posing as an FBI agent in a brazen plot that was ultimately foiled, police said. Mark Anderson, 36, was charged on Thursday with impersonating a federal agent as he allegedly tried to sneak Mangione, 27, out of the Metropolitan Detention Center in Brooklyn. Anderson allegedly lied to officials by claiming he had paperwork 'signed by a judge' authorizing the release of Mangione. Mangione allegedly shot Thompson on a Manhattan sidewalk in the early hours of December 4, 2024 before fleeing the scene on a bike. Officers later said they only found a loaded magazine in the bag at first, but in a later search at a police station they discovered the gun and a silencer.
