Altoona, PA — Luigi Mangione, 26, of Maryland, is in police custody in Altoona, Pennsylvania, as a person of interest in the high-profile murder of UnitedHealthcare CEO Brian Thompson. Thompson was shot and killed outside the New York Hilton Midtown on December 4, 2024. Authorities have confirmed Mangione’s arrest on unrelated gun charges and are now investigating his potential involvement in the murder.
Mangione was traveling aboard a Greyhound bus through Altoona when he was recognized by a McDonald’s employee, who identified him from surveillance images released by the New York City Police Department (NYPD). Police were quickly dispatched to the restaurant on Monday morning, where they apprehended Mangione. New York City Mayor Eric Adams confirmed Mangione matched the description of the suspect in the killing, calling him “a strong person of interest.”
When Mangione was taken into custody, authorities recovered a ghost gun—a firearm capable of firing a 9mm round—along with a suppressor. Police believe the weapon is “consistent with the gun used in the murder.” Further examination suggests the gun may have been manufactured using a 3D printer.
In addition to the firearm, police found a three-page handwritten document believed to provide insight into Mangione’s mindset and motivations. NYPD Commissioner Jessica Tisch stated the document indicates Mangione harbored “ill will toward corporate America.” Authorities are working to analyze the writings more closely to understand his potential reasons for targeting Thompson.
Mangione was also carrying multiple fake IDs, including a fraudulent New Jersey ID that closely matched the identification used by the shooter to check into a hostel in New York City prior to the murder.
The murder occurred on the morning of December 4, when Thompson was shot at point-blank range outside the New York Hilton, where UnitedHealthcare was hosting an investors’ conference. The attack, described as “brazen” and “targeted,” was captured on surveillance footage. In the video, the shooter appears to wait for Thompson, then rushes across the street before opening fire. Following the shooting, the suspect fled the scene by bike, making his way through Central Park and later taking a taxi to the Port Authority bus terminal to board a bus out of the city.
Police are piecing together Mangione’s movements following the murder. Investigators are tracking his travel from New York City to Pennsylvania and are scrutinizing the vast amount of forensic evidence, as well as hours of video footage collected from the scene. On Sunday, NYPD dive teams conducted a search of Central Park near the Bethesda Fountain, though no new evidence was found.
A spokesperson for UnitedHealth Group expressed hope that Mangione’s arrest would provide some sense of relief for Thompson’s family, friends, and colleagues, stating, “We thank law enforcement and will continue to work with them on this investigation.”
Mangione attended the University of Pennsylvania, where he earned a bachelor’s degree and a master’s degree in engineering, with a focus on computer science. His background is now part of the broader investigation into his connection to the murder.
Authorities have indicated that it appears Mangione acted alone, and his name had not been known to investigators prior to his identification in Altoona. As the investigation continues, more details about his possible motive and connections to the murder are expected to emerge.
This arrest marks a significant development in a case that has left the business and insurance communities reeling, and authorities are pressing forward with the investigation to understand the full scope of Mangione’s involvement.
