Luigi Mangione, a 26-year-old Ivy League graduate and former valedictorian, was arrested at a McDonald’s in Pennsylvania after a week-long manhunt.

Mangione is suspected of murdering UnitedHealthcare CEO Brian Thompson in a targeted attack in Manhattan.

Once a promising student, Mangione harbored anti-corporate views, chronicled online, and suffered from chronic back pain that affected his life.

Police found a ghost gun, silencer, and anti-corporate writings in his possession.

Former friends and family described him as once likable but recently estranged and increasingly withdrawn, the Wall Street Journal has reported.

Mangione’s motives and recent actions remain under investigation.
