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.
