Inside the state and federal charges against the man accused of killing UnitedHealthcare’s CEO

A triptych of criminal charges paints a searing, sometimes disparate portrait of the man accused of ambushing and killing UnitedHealthcare’s CEO Brian Thompson as the executive arrived at a Manhattan hotel for his company’s annual investor conference.

Filed separately in state courts in New York and Pennsylvania , and a federal court in Manhattan, and totaling 20 counts, the charges brand Luigi Mangione as both a terrorist and a stalker, accuse him of carrying a ghost gun and a fake ID, and enable prosecutors to seek life in state prison and the federal death penalty.

On Monday, in the last of three court appearances in five days, the 26-year-old Mangione pleaded not guilty in New York state court to an indictment charging him with 11 counts in connection with the Dec. 4 killing, including murder as a crime of terrorism.

Mangione’s state court arraignment followed back-to-back hearings last Thursday in Pennsylvania, where he was arrested Dec. 9, and in federal court in Manhattan, where a judge ordered him jailed without bail on murder, gun and stalking charges.
