State murder trial against Mangione delayed as judge weighs double jeopardy motion
The New York state murder trial for Luigi Mangione, the man who confessed last week in federal court to killing UnitedHealthcare CEO Brian Thompson, has been delayed while a judge weighs whether to dismiss the charges on double jeopardy grounds.
Mangione’s attorneys have officially filed a motion to have the second-degree murder charges vacated. He also faces gun charges related to the shooting of Thompson, who died in December 2024 after Mangione fired bullets into his back on a Manhattan street.
In making the decision to delay proceedings, New York state Justice Gregory Carro also gave the prosecution a deadline of Oct. 9 to respond to the double jeopardy claims and dismissal motion from the defense.
After arguments on the matter, Carro will then decide if and how a trial will move forward.
While Mangione technically did not plead guilty to murdering Thompson, confessing instead to a federal charge of stalking, he admitted to fatally shooting him. On that charge alone, given the context, Mangione faces a life sentence.
New York’s double jeopardy protections—which ensure a defendant is not tried twice for the same crime, in violation of rights protected by the U.S. Constitution—extend to defendants who have already been tried in another jurisdiction for the same crime, even if the charge is not an exact match.
Carro’s interpretation of the law and the argument presented by the Manhattan District Attorney’s Office will be crucial in determining how events unfold, as the defense could have grounds for an appeal if the murder trial continues as planned.
On Friday shortly after Mangione’s confession, the Manhattan D.A. released a statement, vowing to move forward on the state murder charges.
“We are encouraged that Mr. Thompson’s family received a measure of accountability today,” the statement read. “The Manhattan D.A.’s Office remains committed to seeking justice for Mr. Thompson and his family.”
A ‘single tragic event’
Defense attorney Karen Friedman Agnifilo, representing Mangione, has held the position since the beginning that charging her client in both state and federal court was a violation of his civil rights. She reiterated her position outside the courtroom, shortly after Mangione’s admission of guilt.
“It was a single tragic event, yet he's being prosecuted twice for the same conduct,” Agnifilo said, adding that Mangione has now “accepted full responsibility for the death of Brian Thompson.”
A sentencing hearing to decide Mangione’s fate in federal court has been scheduled for Dec. 18.
The 26-year-old Maryland native said he was motivated by a negative experience with medical coverage in relation to a serious back injury he suffered, leaving him in debilitating pain. Notably, however, he did not say he was a UnitedHealthcare member.
Thompson’s family was in attendance in federal court as Mangione recounted the killing.
“On the morning of Dec. 4, 2024, I shot Mr. Thompson in Manhattan and he died,” Mangione said.
“I understood that my actions would place him in fear of death or bodily injury. I knew what I was doing was illegal,” he added.
