Federal prosecutors formally announced plans to seek the death penalty for Luigi Mangione, the 26-year-old accused of murdering UnitedHealthcare CEO Brian Thompson.
Mangione is accused of gunning down Thompson last December outside of a Midtown Manhattan hotel before he allegedly escaped the crime scene by foot, bike, cab and bus to Altoona, Pennsylvania, where he was arrested nearly a week later, marking the end of a six-day manhunt that gripped the nation.
