A federal judge in Manhattan has called Luigi Mangione into court on Friday on two days' notice, three weeks before he is scheduled to stand trial for murder in a New York state courtroom across the street. If the federal case resolves first, New York's unusually strict double jeopardy statute becomes the defense's best argument for killing the state prosecution outright.
Quick Answer
Judge Margaret M. Garnett set a pretrial conference for Friday, August 14, 2026 in United States v. Mangione, No. 1:25-cr-00176, after prosecutors requested one. News organizations reported, citing anonymous sources, that plea discussions were under way. No plea has been entered, and Mangione pleaded not guilty in 2025. Two stalking counts remain after the court dismissed the firearm counts in January, which ended the case as a death penalty matter. Federal trial is set for January 2027; the New York murder trial begins with jury selection on September 8, 2026. A federal conviction by plea before the state jury is sworn would trigger New York's statutory double jeopardy bar.
Allegations Only · Nothing Proven
Luigi Mangione has pleaded not guilty and has not been convicted of any charge in either case. Everything the government has alleged is an accusation it would have to prove at trial. This page is informational and is not legal advice.
A Hearing Called on Two Days' Notice
The order was three sentences long. On Tuesday, August 11, 2026, Judge Margaret M. Garnett of the U.S. District Court for the Southern District of New York directed that a pretrial conference be held in United States v. Mangione on Friday, August 14 at 11:00 a.m., in Courtroom 110 of the Thurgood Marshall Courthouse at 40 Foley Square. It followed a letter from prosecutors that same day requesting a conference. Neither document said what the conference was for.In a case with a trial date five months away and no pending motions, a conference scheduled on two days' notice is unusual enough to be a signal on its own. News organizations reported within a day, citing people with knowledge of the discussions who spoke anonymously, that the parties were in plea talks and that Mangione was expected to plead guilty. The same reports cautioned that the discussions could fall apart before the hearing or during it.
Nothing has been entered on the docket beyond the scheduling order. Mangione pleaded not guilty at his arraignment in April 2025 and that plea stands.
What Is Left of the Federal Case
The indictment returned in April 2025 carried four counts. Two of them are gone.On January 30, 2026, Judge Garnett granted the defense motion to dismiss Counts Three and Four — the firearm charges under 18 U.S.C. §§ 924(j) and 924(c). Count Three was the capital-eligible charge, the one the Justice Department had relied on when it filed a notice of intent to seek the death penalty in April 2025. Its dismissal converted the case into a non-capital prosecution, and the government ultimately declined to take an interlocutory appeal. By March the court was asking the parties whether the court-appointed "learned counsel" required in capital cases should remain on the defense team; he was relieved in April.
What survives are the two stalking counts under 18 U.S.C. § 2261A — one for traveling in interstate commerce with intent to kill, injure, harass or surveil, and one for using interstate facilities including a cellphone and the internet to do the same, each with the sentencing enhancement that applies when the conduct causes death. Each carries a maximum of life.
The same day it dismissed the firearm counts, the court handed the defense a defeat on the evidence. Mangione had moved to suppress the gray backpack recovered in Central Park and everything found in it. Judge Garnett denied the motion, holding that multiple exceptions to the warrant requirement independently justified the search — a pre-transport safety search that turned up a loaded magazine, an inventory search at the police station, and inevitable discovery through the federal search warrant even after excising references to items seen later. The ruling followed an evidentiary hearing in which the court required the government to produce an Altoona, Pennsylvania police officer to testify about the department's property procedures.
Trial was adjourned twice and now stands at January 25, 2027, with in-person jury selection beginning January 5, 2027 from a venire of roughly 800 prospective jurors who will fill out written questionnaires in December.
The State Case Comes First
The Manhattan District Attorney's case is the one closer to trial. Jury selection is scheduled for September 8, 2026 before Justice Gregory Carro in New York Supreme Court.That case has also narrowed. In September 2025, Justice Carro dismissed the terrorism counts as legally insufficient, writing that prosecutors had presented no evidence of a desire to terrorize the public, inspire widespread fear, engage in a broader campaign of violence or coordinate with organized terrorist groups. He noted that while the prosecution emphasized an ideological motive, nothing in the statute converts an ideologically motivated murder into terrorism absent an intent to intimidate a civilian population or coerce a government. Second-degree murder and eight weapons counts remain.
On August 11, 2026 — the same day the federal conference was ordered — the state court ruled that the jury will be anonymous, a measure reserved for cases where jurors may face outside pressure.
Why the Order of Resolution Matters
Two prosecutions for one act coexist because of the dual sovereignty doctrine, which treats the federal government and a state as separate sovereigns entitled to enforce their own laws. The Supreme Court reaffirmed that rule 7 to 2 in Gamble v. United States in 2019. On its own, the Fifth Amendment would not stop New York from trying Mangione after a federal case, or the reverse.New York does not follow the federal floor. Criminal Procedure Law § 40.20 bars separately prosecuting a person for two offenses based on the same act or criminal transaction, and New York courts have read it to reject dual sovereignty — meaning a prior federal prosecution can bar a later state one. The statute then carves out enumerated exceptions.
Two features of that scheme decide the question here. First, the bar depends on a "previous prosecution," which under New York law means one that produced a conviction, including by guilty plea, or that got far enough for a jury to be sworn. A pending federal indictment is not enough — which is why the defense has not been able to use the statute so far, despite arguing from the outset that being charged twice violates Mangione's rights. Second, if a federal conviction does land first, the fight shifts to the exceptions: the district attorney would argue that murder and interstate stalking each require proof of a fact the other does not and that the two statutes are designed to prevent very different harms.
The calendar is what makes this live. A federal guilty plea accepted on August 14 would be a conviction roughly three weeks before a state jury is sworn. That sequence is the one scenario in which the state indictment becomes vulnerable, and it is the reason a routine-looking scheduling order drew national coverage. We walk through the doctrine in more depth in our explainer on double jeopardy and why two courts can charge you for the same act.
The Federal Complaint (PDF)
The FBI agent's affidavit supporting the original December 2024 complaint lays out the government's account of the investigation: the surveillance-camera reconstruction of the shooter's movements from a bus arrival on November 24, 2024 through the shooting outside a Midtown hotel on the morning of December 4, the recovery of shell casings marked with the words "deny," "delay" and "depose," the discovery of a backpack in Central Park, and the arrest in Altoona five days later. It is an accusatory instrument, not evidence, and every assertion in it is an allegation the government would have to prove.The Company at the Center of It
Brian Thompson, who was killed on December 4, 2024, was the chief executive of UnitedHealthcare, the insurance arm of UnitedHealth Group and the largest health insurer in the country by revenue. He was walking to an investor conference when he was shot.The company has spent the period since fighting an unrelated set of civil cases. The largest is the litigation over the February 2024 ransomware attack on Change Healthcare, its claims-processing subsidiary, which exposed data on roughly 192.7 million people and is consolidated as MDL 3108 before Judge Donovan W. Frank in the District of Minnesota; it remains in discovery with class certification still ahead and no settlement. A separate proposed class action in the same district, Estate of Lokken v. UnitedHealth Group, alleges the company used an algorithm called nH Predict to cut short post-acute care for Medicare Advantage members, and the court has ordered broad discovery into how that system worked. UnitedHealth is also among the insurer defendants in provider-side antitrust litigation over out-of-network pricing, and confirmed in July 2025 that it is cooperating with Justice Department investigations into its Medicare Advantage billing. It denies wrongdoing in all of them, and none has produced a settlement or a claim form.
Those cases are legally unconnected to the prosecutions. A criminal case punishes a defendant; it produces no fund and no claim for policyholders. The Change Healthcare litigation is the one with a plausible path to a payout, and we track it on its own case page — along with the fake claim portals that keep appearing for a settlement that does not exist yet.
What Happens Next
Friday's conference is the immediate answer. If a plea is entered and accepted, expect a defense motion to dismiss the state indictment under CPL § 40.20 within days, and expect the district attorney to invoke the statutory exceptions rather than concede. Sentencing in the federal case would follow months later, and the two stalking counts each carry a life maximum, so a plea would not necessarily be a bargain on exposure so much as a maneuver on sequencing.If no plea materializes, the state trial proceeds on September 8 with an anonymous jury, and the federal case continues toward its January 2027 date on the schedule the court set in June.

Frequently Asked Questions
What is happening at the August 14 hearing?
Judge Margaret M. Garnett ordered a pretrial conference for Friday, August 14, 2026 at 11:00 a.m. in Courtroom 110 of the Thurgood Marshall Courthouse in Manhattan. The order was signed August 11, three days earlier, after prosecutors asked for a conference. The order itself does not say what the conference is about. News organizations, citing anonymous sources, reported that plea discussions were under way and that a guilty plea was expected. Those reports were explicit that the talks could collapse before or during the hearing.
What charges does Mangione face in federal court?
Two counts remain: interstate stalking resulting in death and stalking through the use of interstate facilities, both under 18 U.S.C. section 2261A. Each carries a maximum sentence of life in prison. The indictment originally carried four counts, but Judge Garnett dismissed Counts Three and Four, the firearm counts, on January 30, 2026. Because Count Three was the capital-eligible charge, that ruling ended the case as a death penalty prosecution, and the government did not appeal.
Why would the timing of a federal plea matter to the New York case?
New York gives defendants more protection against successive prosecutions than the federal Constitution does. Criminal Procedure Law section 40.20 generally bars a state prosecution for an offense based on the same act as a previous prosecution, including a federal one, subject to enumerated exceptions. That protection requires a previous prosecution that reached a conviction, including by guilty plea, or that proceeded far enough for a jury to be sworn. A federal guilty plea entered before the state jury is sworn would create that predicate. A federal case that is merely pending does not.
When is the New York state murder trial?
Jury selection in the Manhattan case was scheduled to begin September 8, 2026, before Justice Gregory Carro. Mangione faces second-degree murder and eight weapons counts. In September 2025 the court dismissed the terrorism counts as legally insufficient, finding no evidence of a desire to terrorize the public or coerce a government. On August 11, 2026 the court ordered that the jurors' identities be kept anonymous.
Why can both federal and state prosecutors charge the same act?
Under the dual sovereignty doctrine, the federal government and a state are treated as separate sovereigns, each free to define and enforce its own criminal laws, so one act that violates both is treated as two offenses rather than one. The Supreme Court reaffirmed that rule 7 to 2 in Gamble v. United States in 2019. New York is among the states that go further than the federal floor by statute, which is why the double jeopardy question in this case turns on state law rather than the Fifth Amendment.
Has Mangione been convicted of anything?
No. He pleaded not guilty at his federal arraignment in April 2025 and has not been convicted in either case. As of publication no plea had been entered in the federal case. The allegations in the charging documents are accusations the government would have to prove at trial, not established facts.
Does either criminal case create a claim for UnitedHealthcare customers?
No. A criminal prosecution punishes a defendant. It creates no settlement fund, no class and no claim form for anyone else. UnitedHealth does face separate civil class actions, including the Change Healthcare data breach litigation consolidated as MDL 3108 in the District of Minnesota, but those cases are legally unrelated to the criminal proceedings and none has reached a settlement or opened a claims process.
