Unitedhealthcare CEO murder suspect Luigi Mangione pleads not guilty

Luigi Mangione, the man accused of fatally gunning down health insurance executive Brian Thompson on a Manhattan street, pleaded not guilty on Monday to New York state murder charges that brand him a terrorist.

Mangione, 26, was escorted into Judge Gregory Carro's 13th-floor courtroom in the New York state criminal courthouse in lower Manhattan with a court officer on each arm, and a procession of a half dozen officers following him. He was in handcuffs and shackles, and wore a burgundy sweater over a white-collared shirt.

Luigi Mangione leaned into a microphone and said "not guilty" when Carro asked how he pleaded to the 11-count indictment charging him with murder as an act of terrorism and weapons offenses.
