Luigi Mangione, a 26-year-old app developer and former University of Pennsylvania graduate, has been arrested in connection with the murder of UnitedHealthcare CEO Brian Thompson. The 50-year-old executive was fatally shot outside the New York Hilton Midtown in Manhattan on December 4, 2024, in what authorities have described as a targeted attack.

Following the shooting, Mangione fled New York, traveling across Pennsylvania to evade capture. Police apprehended him on December 9 at a McDonald’s in Altoona, Pennsylvania, after he was recognized by rookie officers.

At the time of his arrest, Mangione was carrying a passport, over $10,000 in cash, and a backpack containing a 3D-printed pistol and silencer that may have been used in the crime. He was also found with a fake ID. Mangione has been charged with murder and other related offenses​.

Investigators are exploring Mangione’s possible motive for the attack. While his recent social media posts suggested frustration with healthcare-related issues, particularly after a major spinal surgery, no clear motive has been confirmed.

Some reports suggest that Mangione may have had personal grievances with corporate America, given his online comments about healthcare denial practices​. His background includes ties to several U.S. cities, including San Francisco, and he had reportedly been living in Hawaii before the incident​.
