The New York judge treated him very badly Luigi Mangione On Monday, May 18, ruling that key evidence against the alleged CEO killer, including the weapon and manifesto documents, could be used in his upcoming federal trial, Us Weekly can confirm.
The judge Gregory CarroMangione's decision came after a nine-day trial in Manhattan Criminal Court in December 2025, where Mangione's legal team argued that items found in their client's purse — including a 3D-printed handgun with a silencer and a notebook that prosecutors said detailed his intent to “taunt” (health wise) the courtroom because police did not have a search warrant when they arrested Mangione.
Mangione's attorneys also fought to suppress statements the 28-year-old made before he was arrested at a McDonald's in Altoona, Pennsylvania, in December 2024. Bodycam footage played in court corroborated prosecutors' claim that police questioned Mangione about 20 minutes before giving him his Miranda rights.
Carro ruled during Monday's hearing, Mangione, who attended wearing a navy suit, said the gun and the handbook could be brought before the judge when the trial begins on September 8 because the police found both items at their station. However, in Mangione's narrow victory, the judge found that other evidence, including a loaded magazine, passport, cell phone, wallet and computer chip, was inadmissible because of what he called an “improper, warrantless search” at McDonald's.
The Ivy League graduate pleaded not guilty to 11 charges, two of which Carro dropped in September 2025 due to insufficient evidence of terrorism. He faces life in prison in the New York case.
Mangione was also charged with four counts following his arrest. However, a US District Judge Margaret M. Garnett dismissed two counts, including one of murder with a firearm, in January, and spared Mangione the death penalty.
At the time, Garnett also ruled that the gun and other evidence could be used in Mangione's trial, which begins in January 2027. He pleaded guilty to that charge as well.
Additionally, the Maryland native faces five charges in Pennsylvania, including carrying a firearm without a license and false identification to law enforcement. He did not enter a plea there before being extradited to New York in what his lawyers — and Mangione himself — called “double jeopardy,” a legal term used to describe someone who is being prosecuted twice for the same crime.
Suspected murderer Luigi Mangione allegedly started a to-do list after the killing of UnitedHealthcare executive Brian Thompson, and former police veteran testified in court on Monday, December 8. Christy Wasser of the Altoona Police Department in Pennsylvania said that during his trial in New York City, she found a red letter inside Mangione's backpack. […]
Since his arrest, Mangione has amassed tens of thousands of supporters because of his physical appearance and broader frustration with the health care system in the United States. His legal defense fund has raised more than $1.5 million so far, and he receives hundreds of letters a day at the Metropolitan Detention Center (MDC) in Brooklyn.
“I am shocked – and grateful – for everyone who has written to me to share their stories and express their support,” Mangione said in one of his public statements in February 2025. “Strongly, this support has transcended political, ethnic and class divides, as the MDC spans the country and the world. I took the time to write and look forward to hearing more in the future.”
