Judge Dismisses Terrorism Charges Against Luigi Mangione in UnitedHealthcare CEO Killing

Prosecutors failed to prove that the suspect acted with terroristic intent, but the judge left intact overlapping federal and state charges, including murder.

A New York state judge has dismissed terrorism charges against Luigi Mangione, accused of fatally shooting UnitedHealthcare CEO Brian Thompson last December, but ruled the case will proceed on an intentional murder charge and other counts.

Justice Gregory Carro issued his decision on Sept. 16 in Manhattan Supreme Court, finding that prosecutors failed to prove Mangione killed in furtherance of terrorism under New York law.

“Counts 1 and 2, charging defendant with Murder in the First Degree (in furtherance of an act of terrorism) and Murder in the Second Degree as a Crime of Terrorism, are dismissed as legally insufficient,” Carro wrote. “The People presented legally sufficient evidence of all other counts, including Murder in the Second Degree (intentional).”

The ruling tosses two of the most serious charges but leaves intact the rest of the indictment, including intentional second-degree murder, weapons possession, and forgery. Mangione has pleaded not guilty.

Prosecutors allege Mangione shot Thompson with a 9 mm pistol equipped with a silencer outside the Hilton hotel in Midtown Manhattan on Dec. 4, 2024, as the CEO arrived for UnitedHealthcare’s annual investor conference.

Surveillance footage showed a masked gunman firing from behind. Shell casings recovered at the scene were etched with the words “delay,” “deny,” and “depose,” echoing longstanding criticisms of insurance industry claims practices.

After a several-day manhunt, Mangione was arrested at a McDonald’s in Altoona, Pennsylvania. Investigators said he was carrying a backpack containing the alleged murder weapon, ammunition, a fake New Jersey driver’s license, cash, and a red notebook. In one entry, Mangione allegedly wrote: “I finally feel confident about what I will do. The target is insurance. It checks every box.”

His defense team argued the backpack search was illegal because police lacked a warrant, and sought to suppress the evidence. The court granted hearings on the suppression motions but declined to dismiss the state case or put it on hold while federal proceedings move forward.

Mangione faces parallel prosecutions in three jurisdictions.

In April, prosecutors indicted him on stalking and firearms charges, including murder through the use of a firearm, a count that carries the death penalty if he is convicted. U.S. Attorney General Pam Bondi described the crime as “a premeditated, cold-blooded assassination that shocked America.”

In Pennsylvania, the Blair County district attorney has charged Mangione with forgery, possession of an instrument of crime, and giving a false ID to an officer. He is scheduled to appear for a pretrial motion hearing there on Nov. 7.

Mangione’s lawyers say the overlapping state, federal, and Pennsylvania prosecutions put him in an “untenable situation” and violate the Constitution’s double jeopardy clause, which bars prosecution for two offenses based on the same act. The judge rejected arguments that the New York case should be dismissed or delayed, citing the “dual sovereignty” doctrine allowing separate prosecutions.

“As the United States Supreme Court has held, ‘where there are two sovereigns, there are two laws, and two offenses,’” Carr wrote. “A crime ‘against two sovereigns constitutes two offenses because each sovereign has an interest to vindicate.” [...] Thus, there is no double jeopardy violation.”

With the terrorism counts dropped, the case moves forward as a straightforward murder trial.
