## The Crime and Arrest
On December 4, 2024, 50-year-old Brian Thompson was walking to UnitedHealth Group’s annual investor conference outside the New York Hilton Midtown when Luigi Mangione ambushed him. Prosecutors say Mangione waited in the vicinity for about an hour before opening fire, then escaped through Central Park and later through Manhattan.
Mangione was arrested on December 9 at a McDonald’s in Altoona, Pennsylvania—roughly 375 kilometers west of New York City. Initially using a false name and identity, he later admitted who he was. Law enforcement recovered a 3D-printed pistol linked to the shooting, along with a notebook in which Mangione made references to wanting to “wack” a health insurance executive.

## Plea in the Federal Case
Mangione entered the guilty plea in federal court in New York on stalking charges tied to the killing. This resolution clears one of his two criminal fronts: the federal case. Previously, Mangione had pleaded not guilty in both his federal and New York state trials.
During the plea, he made a succinct admission in open court: “I shot Mr Thompson, and he died. I knew what I was doing was illegal.” The federal case dates back to the December shooting.

## Sentencing and Capital Punishment Removed
Sentencing for the federal charges is set for December 18.
Earlier, federal prosecutors had the option of seeking the death penalty. Then-US Attorney General Pam Bondi had described the killing as “a premeditated, cold-blooded assassination that shocked America” and sought to pursue capital punishment. Yet in January 2026, Judge Margaret Garnett ruled to bar the death penalty in this case, which required dismissal of the federal murder charge that made such a sentence possible.

## State Prosecution Ongoing
While the federal case is resolved via plea, Mangione still faces charges in New York state court. In September 2025, terrorism charges were dismissed by Judge Gregory Carro, though second-degree murder and other charges remain.
The state trial was slated to begin next month from now (i.e. September 2026), but Mangione’s team has filed a motion to dismiss the state-level case on the basis of double jeopardy. He has argued that being tried in both federal and state jurisdictions amounts to “the same trial twice,” citing fairness concerns.

## Evidence and Investigation
Surveillance footage played a key role. It captured the shooter outside the Hilton just before Thompson was killed. Mitchell of intensive investigation revealed Mangione had arrived in New York on November 24, 2024, using a fake identity and staying in a hostel.
Further, police found a discarded backpack in Central Park containing Monopoly money and a black Tommy Hilfiger jacket. These items, along with the weapon and notebook with incriminating references, helped build the case.
