The suspect in the murder of UnitedHealth Group executive Brian Thompson is facing both federal and state charges.
Luigi Mangione, 26, has been charged with federal murder, stalking, and the use of an illegal gun silencer.
These charges were outlined in a criminal complaint filed by federal prosecutors in Manhattan.
Mangione allegedly spent months planning the attack, motivated by his disdain for the health insurance industry and its executives.
He was transferred to New York City police custody after waiving extradition rights during a court hearing in Pennsylvania, where he was captured after a five-day manhunt.
Health insurance
In a notebook found by Altoona police, Mangione wrote extensively about his hostility towards the health insurance sector.
A specific entry indicated his intention to target the chief executive of an insurance company at an investor conference.
He labelled the event a “true windfall,” suggesting it would convey a significant message.
Police discovered a letter addressed “To the Feds,” in which Mangione claimed he acted independently.
In this letter, he described his actions as involving basic skills in social engineering and computer-aided design, indicating a calculated approach.
