Luigi Mangione faces new federal charges over CEO's murder
Luigi Mangione has faced a federal court in Manhattan, charged with the murder of healthcare CEO Brian Thompson
Federal charges were filed against Mangione today, in addition to state charges he already faced on a state level in New York and Pennsylvania
His lawyer, Karen Friedman Agnifilo, told the court that the overlapping charges were "confusing" and unlike anything she had seen in 30 years of practicing law
Mangione did not enter a plea and will be kept in custody until his next court appearance
Earlier, the suspect was escorted from a NYPD helicopter by a large group of police, FBI and ATF agents, some wearing body armour and carrying rifles
The 26-year-old was arrested in a McDonald's in Altoona, Pennsylvania five days after Thompson was shot and killed on a Manhattan street outside a Hilton hotel
