Luigi Mangione, the alleged killer of UnitedHealthcare CEO Brian Thompson, has pleaded guilty to federal charges stemming from the murder, marking a major development in a case that has attracted international attention.
Online tribune reports that Thompson, 50, was shot and killed on December 4, 2024, outside a hotel in Manhattan, New York, where he was scheduled to attend an investor conference.
Surveillance footage captured the gunman fleeing the scene, triggering a nationwide manhunt that ended five days later when Mangione was arrested at a McDonald’s restaurant in Altoona, Pennsylvania.
Police said a 3D-printed firearm and other items believed to link Mangione, 28, to the shooting were recovered at the time of his arrest.
Investigators alleged that Mangione had followed Thompson before the attack and investigated the executive’s movements.
His lawyers have said he was frustrated with the U.S. healthcare system because of his own health problems.
The case subsequently sparked widespread debate about the American healthcare industry, with some people expressing sympathy for Mangione’s complaints and condemning the murder.

Mangione initially faced murder and other charges both in New York and in federal court. Several federal charges were later dismissed, including a federal murder charge that could have exposed him to the death penalty.
On Friday, August 14, 2026, Mangione pleaded guilty in federal court to two counts of stalking that resulted in Thompson’s death.
During the trial, he admitted to shooting Thompson in Manhattan and acknowledged that he knew the act was illegal and could result in death.
Mangione faces a possible life sentence, and federal sentencing is scheduled for December 18.
However, he still faces a separate murder case in New York, where his trial is scheduled to begin on September 8.
His attorneys are seeking to have the New York case dismissed following his federal guilty plea.
Thompson’s family welcomed Mangione’s guilty plea as a step toward justice, while authorities reiterated that grievances against the health system could not justify violence.
