Judge Bars Death Penalty in Luigi Mangione Case, Clears Way for Faster Trial

A federal judge on Friday shut down prosecutors’ effort to seek the death penalty against Luigi Mangione, removing capital punishment as a possible sentence in the point-blank Manhattan killing of UnitedHealthcare CEO Brian Thompson last year.

Prosecutors had warned they would appeal if the death penalty were taken off the table, a move that could have significantly slowed the case. Capital cases require far more preparation, and the next phase would not have begun until January 2027. With that option eliminated, the case is now set to move forward more quickly, with opening statements scheduled for Oct. 13.

Mangione’s defense team argued that the charges used to justify pursuing the death penalty against the 27-year-old were legally defective. They also said the government tainted the case by publicly announcing its intention to seek capital punishment before a grand jury had returned an indictment.

U.S. District Judge Margaret Garnett also denied a separate defense request to throw out key evidence, including Mangione’s backpack and what was found inside it at the time of his arrest. Defense lawyers claimed police violated standard procedures during the search and seizure, but the judge declined to suppress the evidence.

Mangione has pleaded not guilty to both federal and state murder charges, which still expose him to a possible life sentence. A date for the state trial has not yet been set.

Thompson was shot and killed on Dec. 4, 2024, as he walked toward a Manhattan hotel where UnitedHealth Group was holding its annual investor conference. Surveillance footage captured a masked gunman approaching from behind and firing the fatal shots.

Police first searched Mangione’s backpack inside a McDonald’s restaurant, where he was arrested while eating breakfast. Prosecutors said the initial search was lawful because Altoona police policy requires officers to promptly examine a suspect’s belongings at the time of arrest to check for dangerous items. Investigators later obtained a warrant as well.

Among the items recovered at the restaurant was a loaded gun magazine.

Officers continued examining the backpack later at a police station, where they discovered a firearm and a silencer. During what prosecutors described as an “inventory search,” police also found a notebook and additional writings that appeared to include to-do lists and possible escape plans, according to testimony.

That type of search, which involves itemizing every piece of property seized from a suspect, is mandated under Altoona police policy, prosecutors said. Legal battles over search warrants and police procedures are common in criminal cases, given the complexity of the rules involved.

As part of her review, Judge Garnett ordered federal prosecutors to turn over the affidavit used to secure the federal search warrant. During the hearing, Mangione’s attorney, Marc Agnifilo, questioned Snyder about a police department general order that took effect Feb. 1, 2016, outlining arrest, search, and seizure practices.

Defense lawyers maintain that searching the backpack before a warrant was issued may have shaped how the affidavit was written. Prosecutors countered that the document did not include specific references to items found in the bag, such as the notebook or its contents.
