From wealth and success to murder suspect, the life of Luigi Mangione took a hard turn

Luigi Nicholas Mangione, the suspect in the fatal shooting of a healthcare executive in New York City, apparently was living a charmed life: the grandson of a wealthy real estate developer, valedictorian of his elite Baltimore prep school and with degrees from one of the nation's top private universities.

Friends at an exclusive co-living space at the edge of touristy Waikiki in Hawaii where the 26-year-old Mangione once lived widely considered him a “great guy,” and pictures on his social media accounts show a fit, smiling, handsome young man on beaches and at parties.

Now, investigators in New York and Pennsylvania are working to piece together why Mangione may have diverged from this path to make the violent and radical decision to gun down UnitedHealthcare CEO Brian Thompson in a brazen attack on a Manhattan street.

The killing sparked widespread discussions about corporate greed, unfairness in the medical insurance industry and even inspired folk-hero sentiment toward his killer.
