The U.S. Attorney’s Office said Luigi Mangione pleaded guilty on August 14 to two federal stalking counts resulting in Brian Thompson’s death. According to the announcement, the pleas resolve guilt on those federal counts. They also set up a New York fight over whether the state may try overlapping murder and weapons charges.
Key Facts
- Federal sentencing is scheduled for December 18, 2026.
- Each federal count carries a maximum potential sentence of life imprisonment.
- A New York judge has not decided Mangione’s request to dismiss Counts Three through Ten.
- The postponed state case is scheduled to return to court on December 10.
What the federal pleas establish
Federal prosecutors announced that Mangione entered the pleas before U.S. District Judge Margaret M. Garnett in Manhattan.
The offenses are interstate stalking resulting in death and cyberstalking through use of interstate facilities resulting in death.
Each count permits a maximum sentence of life in prison, according to the U.S. Attorney’s Office. That maximum is not the sentence Mangione will necessarily receive.
Judge Garnett is scheduled to sentence him on December 18. Until then, probation ordinarily prepares a presentence report to help the judge determine an appropriate sentence.

Which state charges are being challenged
Mangione’s defense asked the New York court to dismiss Counts Three through Ten, which include second-degree-murder and weapons charges.
The motion does not seek dismissal of Count Eleven. That count concerns an allegedly fraudulent identification card, which the defense describes as a separate transaction.
The defense argues that New York law bars the state from prosecuting Counts Three through Ten after the federal pleas. Federal and state cases can generally coexist, but the defense invokes New York’s broader protections against successive prosecutions arising from the same act or criminal transaction.
Those are defense arguments, not findings by the court.
The Associated Press reported that the Manhattan district attorney’s office plans to oppose dismissal. Its formal response was not due as of August 20.
The state trial has been postponed
The Associated Press reported that the state trial previously scheduled for September 8 was postponed indefinitely while the dismissal motion is litigated.
Justice Gregory Carro’s August 17 order did not grant or deny dismissal. It gave prosecutors until October 9 to respond and the defense until October 30 to reply.
The order adjourned the case to December 10, the next court date. December 10 is not a replacement trial date.
Mangione’s not-guilty plea remains in place in the state case.
What happens next
Judge Garnett is scheduled to impose the federal sentence on December 18. The maximum sentence on each admitted count is life imprisonment, but no sentence has been imposed.
The September 8 state trial will not proceed as scheduled. The New York court must first consider the challenge to Counts Three through Ten, while Count Eleven remains outside that dismissal request.
No state court has dismissed the challenged charges or accepted either side’s legal position.
