Who is CEO killing suspect Luigi Mangione?

Luigi Mangione, a 26-year-old former Ivy League student, has been arrested as a suspect in the murder of United Healthcare CEO Brian Thompson. NYPD investigators say Mangione’s photos, taken when he lowered his mask to flirt at a hostel, were key in cracking the case. Mangione, originally from Maryland with ties to San Francisco and Honolulu, penned a handwritten manifesto expressing anti-corporate sentiments.
