Luigi Mangione is expected to plead guilty as early as Friday in the federal case accusing him of stalking and killing UnitedHealthcare CEO Brian Thompson, according to a person familiar with the matter. The person, who was not authorized to talk publicly about the case and spoke to The Associated Press on the condition of anonymity, cautioned that Mangione could change his mind. A hastily scheduled hearing is set for Friday in Manhattan federal court.
Mangione has been charged in both federal and state court in New York. His state murder trial is set to begin Sept. 8. Both cases carry the possibility of a life sentence. The federal case involves two counts of stalking, with charges centered on crossing state lines and using interstate facilities while planning and carrying out the attack. Mangione has previously pleaded not guilty to all charges.
What the Left Is Saying
Progressive critics have pointed to the killing as emblematic of frustrations with the health insurance industry's denial practices. Surveillance video showed "delay," "deny" and "depose" written on ammunition recovered from the scene, echoing phrases used by advocates criticizing insurers' claim rejections. Mangione became a cause célèbre for people upset with the industry, drawing supporters to court appearances wearing green clothing and "FREE LUIGI" shirts. An online fundraiser for his legal defense raised more than $1.5 million.
Defense attorneys have cited Mangione's public statements opposing what he called "double jeopardy by any commonsense definition," arguing that two trials for essentially the same conduct would be unjust. His lawyers have also noted their client is an Ivy League graduate from a wealthy Maryland family, framing his background as inconsistent with typical criminal profiles. The defense previously explored but then abandoned pursuit of a psychiatric defense involving claims of extreme emotional disturbance.
What the Right Is Saying
Law enforcement and corporate leaders have emphasized that Thompson was ambushed in a premeditated attack while walking to an investor conference. Federal prosecutors have argued their case is distinct from state charges, focused on Mangione's use of interstate facilities, buses, the internet, and out-of-state hostels while planning the killing. State prosecutors objected in a letter last month to any guilty plea wiping out their murder case, writing that "any guilty pleas must account for the seriousness of defendant's offenses, the loss of an innocent life, the impact on the victim's family."
Business leaders have pointed to the broader implications for corporate security and executive safety. UnitedHealth Group employs 440,000 people and covers 53 million customers nationwide. The company reported $327 billion in revenue last year, making it one of the largest employers in Minnesota where it's headquartered. Corporate groups have noted increased attention to threat assessment protocols since the December 2024 killing.
What the Numbers Show
UnitedHealth Group reported $20 billion in net earnings for 2025 and serves approximately 53 million people through its various insurance products. Thompson, 50, was killed outside a Manhattan hotel on Dec. 4, 2024, while walking to UnitedHealth's annual investor conference. Mangione, 28, was arrested five days later at a McDonald's in Altoona, Pennsylvania, about 370 kilometers west of Manhattan. The FBI confirmed the 3D-printed pistol found in his backpack matched shell casings at the crime scene. A notebook recovered during his arrest contained what authorities described as statements detailing intent to kill an insurance executive.
The Bottom Line
If Mangione follows through with a guilty plea, it would resolve only the federal case and potentially set up a legal battle over double jeopardy protections under New York law. State prosecutors argue their murder and weapons charges are distinct from the federal stalking counts because they focus on the killing itself rather than interstate travel to plan it. A successful double jeopardy motion by Mangione's defense could derail the state case entirely, though state prosecutors have signaled they would appeal. Judge Margaret Garnett ruled in January that evidence from Mangione's backpack including the firearm and notebook could be used against him. What happens next will likely hinge on how New York's top court rules on whether federal and state charges arising from the same course of conduct can both proceed.
