Luigi Mangione is back in a sealed New York courtroom for a proceeding tied to the killing of UnitedHealthcare CEO Brian Thompson, as two separate 2026 trials—state murder and federal stalking—move toward jury selection and could ultimately determine whether h
Luigi Mangione is heading back into a sealed New York courtroom today. a quiet return that carries a heavy weight: the case against him over the killing of UnitedHealthcare CEO Brian Thompson remains among the most closely watched criminal matters in the country. yet the proceedings are limited in what the public can see.
The hearing is tied to the Thompson case, and the closure itself has become part of the story. A clerk offered no explanation for why the courtroom would be closed. a detail that underscores how much tension still hangs over what evidence can be presented. how admissibility rulings will shape the fight. and how two parallel tracks—state and federal—are moving toward trial.
Mangione. 28. remains held at the Metropolitan Detention Center in Brooklyn. where he has been since his extradition to New York in December 2024. The detention facility has also been the site of unusual incidents tied to his case. including a Minnesota man charged with impersonating an FBI agent in what appeared to be an effort to secure Mangione’s release.
For Thompson’s family. for the people who have rallied around Mangione online. and for prosecutors working on two different timelines. the next few months carry a particular urgency. A New York state murder trial is scheduled for September 8. and a federal stalking trial is set to begin jury selection on October 5. Mangione has pleaded not guilty in both cases.
The timeline of how the case reached this point begins with months of disappearance and ends with multiple courts testing the same core evidence.
In the summer into the fall of 2024, Mangione fell out of contact with his family. His mother filed a missing-person report in San Francisco.
On November 24, 2024, he arrived in New York City by bus and checked into a hostel under a fake ID. In late November through December 3, he moved between hostels, and surveillance showed him scouting the area around the New York Hilton Midtown hotel.
On December 4, 2024, at 6:44 a.m., Brian Thompson was shot outside the Hilton while walking to an investors’ meeting. About an hour later—at 7:30 a.m.—the suspect fled toward the George Washington Bridge Bus Station and left the city.
Six days later, on December 9, 2024, Mangione was arrested at a McDonald’s in Altoona, Pennsylvania, after a customer recognized him. On December 19, 2024, he was extradited to New York, and a federal complaint was filed the same day.
By December 23, 2024, he pleaded not guilty to state charges.
In 2025, terrorism-related murder charges were dismissed in state court, and federal prosecutors announced their intent to seek the death penalty. That move did not last.
In January 2026, a federal judge dismissed the death-eligible charges, ruling that they were legally incompatible with the stalking counts.
What remains at the center of both cases is how the search and seizure of Mangione’s backpack will play in front of jurors.
On May 18, 2026, a state judge suppressed some backpack evidence but allowed the gun, suppressor, and notebook. The details of what officers said they found in the backpack are among the most contested in the entire case: officers reported finding a 3D-printed gun. a suppressor. ammunition. fake IDs. and a red notebook containing writings critical of the health insurance industry.
In federal court, Judge Margaret Garnett ruled that the search was “reasonable,” allowing the gun, suppressor, notebook, and writings into evidence.
In state court, Judge Gregory Carro suppressed items tied to the initial warrantless search—such as Mangione’s phone, passport, and computer chip—but allowed the gun, suppressor, and notebook because they were recovered during a later search at the police station.
Prosecutors in both cases are also expected to focus on shell casings found at the scene marked with the words “deny,” “delay,” and “depose,” which investigators say may reflect motive.
The person at the center of all of this is Brian Thompson, 50, who led UnitedHealthcare, the nation’s largest health insurer, and had worked at the company since 2004. He was in New York City for an investors’ meeting when he was shot in the back outside the Hilton Midtown on December 4, 2024.
Thompson had faced public criticism over the company’s claim-denial practices, and his family said he had received threats before the shooting. The killing triggered national outrage, intense political debate, and a surge of online hostility toward the health insurance industry.
In the aftermath, UnitedHealth Group’s stock fell sharply. Executives hired private security, and the company removed leadership photos from its website.
As the legal process grinds toward two separate trials, the public culture around the case has grown just as intensely.
Mangione’s supporters have developed an unusually large following, portraying him as a symbol of anger toward the health insurance industry. Graffiti, memes, and merchandise have appeared across the United States and abroad, while the hashtag #FreeLuigi has been shared tens of thousands of times.
This week. the movement drew fresh scrutiny when three self-styled supporters—calling themselves “The Mangionistas”—were granted press passes to attend a sealed hearing. New York City Mayor Zohran Mamdani said the passes should never have been issued and ordered a review of the city’s credentialing process.
Outside the courthouse, members of the group made inflammatory remarks about Thompson. The backlash was immediate and bipartisan: former Mayor Eric Adams called the comments “reprehensible,” and City Council members said activists should not be allowed to pose as journalists at official proceedings.
Despite the condemnation, the group has continued to post commentary to small but active social media audiences, framing its presence as an act of political expression.
In a case already defined by what juries will be allowed to hear. the sealed nature of today’s proceeding and the anger swirling around it—both in court and outside—are part of the same story. Mangione remains in custody. The evidence disputes will continue to shape what reaches the courtroom. And with September 8 and October 5 now locked in for separate trials. the timeline is tightening toward decisions that could ultimately decide whether the country sees a life sentence—or something far less certain.
