Mangione pleads not guilty to state charges in health insurance CEO killing

Luigi Mangione, the 26-year-old man accused of killing UnitedHealthcare CEO Brian Thompson in Manhattan earlier this month, pleaded not guilty on Monday to the state charges he is facing, including murder. 

Mangione’s not guilty plea comes after he was extradited late last week from Pennsylvania, where he was initially found and arrested, to New York, where the trial will be held. He is also facing four federal counts, including a charge of murder through use of a firearm, which could allow prosecutors to seek the death penalty.
