Luigi Mangione, the man accused of killing UnitedHealthcare CEO Brian Thompson, appeared in federal court in New York City on Friday, where he formally entered a not guilty plea to a series of serious charges — including murder through the use of a firearm.
Mangione faces four federal charges in total:
- One count of murder with a firearm
- Two counts of interstate stalking
- One firearms-related offense for allegedly using a silencer during the fatal shooting
Court Appearance and Next Steps
A courtroom sketch captured Mangione during his arraignment on Friday, where Judge Elizabeth Williams presided over the hearing. She ordered all discovery materials — including evidence, witness lists, and any supporting documents — be turned over to the defense by May 27.
The appearance was brief but tense, as federal prosecutors continue to push for the death penalty — an outcome Mangione’s legal team strongly opposes. Legal filings submitted earlier this month clearly outlined both positions.

The Shocking Killing That Gripped the Nation
Mangione was arrested in December 2024, just days after allegedly ambushing Brian Thompson — the then-CEO of UnitedHealthcare — and fatally shooting him on a New York City street in the early morning hours.
Authorities claim Mangione used a firearm equipped with a silencer, making the slaying all the more calculated and chilling. A multi-day manhunt ensued, ending when a McDonald’s employee in Pennsylvania recognized him and alerted police, leading to his arrest.
A Diary of Darkness: Premeditation Alleged
One of the most disturbing revelations in the case comes from Mangione’s personal diary, which prosecutors say contains months of premeditated planning.
In one entry, Mangione allegedly wrote, “Insurance is the target … it checks all the boxes.” This chilling note, along with others, paints a picture of a man obsessed with targeting high-ranking figures in the healthcare industry — though his exact motivations remain unclear.
Investigators believe Mangione may have harbored a grudge against the healthcare system or its executives, though no formal motive has been confirmed by the court at this stage.
State and Federal Charges Loom
Mangione faces both state and federal charges in this case. He previously pled not guilty to state-level murder charges in December, and now his federal trial preparation is underway. A trial date has yet to be scheduled for either case.
Public Reaction: Divided and Emotional
The case has drawn strong reactions across political and media landscapes.
- Former President Donald Trump has vocally condemned Mangione, labeling him and his supporters as dangerous.
- Meanwhile, journalist Taylor Lorenz, who has faced criticism for past commentary, has taken a more nuanced stance, cautioning against rushing to judgment.
The incident has also sparked conversations about mental health, gun control, and corporate accountability, as some online communities attempt to dissect the motivations behind Mangione’s alleged actions.
The Charges He Faces
Here’s a breakdown of the federal charges Mangione is currently facing:
- 18 U.S. Code § 924(j) – Murder through the use of a firearm, which could lead to life imprisonment or the death penalty.
- 18 U.S. Code § 2261A – Interstate stalking, for allegedly targeting Thompson across state lines.
- 18 U.S. Code § 922(k) – Possession of a firearm with a removed or altered serial number.
- 18 U.S. Code § 924(c) – Using a firearm during a violent crime, potentially enhanced due to the alleged use of a silencer.
What’s Next?
With discovery materials due by May 27, legal experts anticipate pretrial motions will follow, potentially challenging aspects of the diary evidence, the weapon used, and federal jurisdiction claims.
It’s unclear when the trial will begin, but given the gravity of the case and the federal interest in pursuing the death penalty, legal proceedings could stretch well into 2026.
