Luigi Mangione pleaded guilty Friday in New York federal court to stalking that led to him killing UnitedHealthcare CEO Brian Thompson on a midtown Manhattan street in December 2024.
Mangione’s lawyers immediately afterward filed a motion in New York state court saying that charges of murder and other counts in that court for Thompson’s slaying should be tossed out under the state’s double jeopardy law.
Mangione said Friday in Manhattan U.S. District Court that he traveled to New York with the intention of killing Thompson after reaching out to UnitedHealthcare and pretending to be an investor ahead of a conference at a Manhattan hotel.
“I shot Mr. Thompson in Manhattan, and he died,” Mangione said, according to MS NOW. “I knew what I was doing was illegal.”
Thompson’s company, which is a division of UnitedHealth Group, is the largest provider of health insurance in the United States.

Mangione, who said in court that he was motivated after suffering years of pain from a broken back, faces a maximum possible sentence of life in prison. Sentencing is scheduled for Dec. 18.
Manhattan U.S. Attorney Jamie McDonald said he will seek a sentence of life for the charges of interstate stalking resulting in Thompson’s death, and use of electronic communications for the purpose of stalking.
McDonald and Amanda Houle, chief of the office’s Criminal Division, were sitting in the front row of court next to Thompson’s widow and family during Friday’s plea hearing, MS NOW reported. United Healthcare executives sat in the row behind them.
“Today’s guilty plea marks an important step toward justice for Brian and for our family,” Thompson’s family said in a statement. “While nothing will ease the pain of losing him, we are grateful that the federal justice system has held the person responsible for this heinous act accountable.”
“Now we look to the court to ensure that sentencing reflects the severity of this crime,” the family said. “We remain mindful that additional proceedings in New York and Pennsylvania are still to come, and we will continue to seek the justice Brian deserves.”
Mangione’s plea came weeks before jury selection is scheduled to start for his Manhattan Supreme Court trial on a charge of murdering Thompson.
It is not clear if that trial will happen, given defense attorneys’ new motion asking a judge to toss the state charges because of Friday’s plea in federal court.
Double jeopardy bars prosecuting a defendant twice for the same conduct.
A spokeswoman for Manhattan District Attorney Alvin Bragg, whose office is prosecuting Mangione in state court, said in a statement the office would fight the effort to dismiss the case.
“Since December 2024, the Manhattan D.A.’s Office has been tirelessly preparing to pursue a trial conviction in New York State Supreme Court for the alleged cold-blooded murder of Brian Thompson,” the spokeswoman said.
“We are encouraged that Mr. Thompson’s family received a measure of accountability today. While federal sentencing is pending, we are prepared to litigate the defense motions,” the spokeswoman said. “The Manhattan D.A.’s Office remains committed to seeking justice for Mr. Thompson and his family.”
UnitedHealth Group, in a statement after the plea hearing, said, “Brian Thompson’s life was cut short by an act of violence that devastated everyone who knew and loved him.”
“We are grateful to law enforcement for bringing Brian’s murderer to justice, and our thoughts remain with Brian’s family and loved ones during this difficult time,” the company said.
