By Aaron KaterskyJanuary 29, 2026, 12:50 PMA Minnesota man allegedly tried to break Luigi Mangione out of jail in New York, law enforcement sources told ABC News. Mark Anderson, 36, was charged Thursday with impersonating a federal agent after authorities said he showed up at the Metropolitan Detention Center in Brooklyn claiming to be an FBI agent with a court order to release Mangione, sources said. Mangione is being held at MDC-Brooklyn while he awaits federal and state trials for the assassination-style killing of UnitedHealthcare CEO Brian Thompson in December 2024. The complaint does not name Mangione, but law enforcement sources told ABC News that is who Anderson was seeking. Meanwhile, Mangione is due in court on Friday; the judge overseeing his federal case may decide if the death penalty will remain a sentencing option if he's convicted.
