Luigi Mangione's federal trial opening statements set for Jan. 25

(NEW YORK) -- Accused killer Luigi Mangione will stand trial in Manhattan federal court beginning Jan. 5 with jury selection, followed by opening statements on Jan. 25, Judge Margaret Garnett said Monday.

Garnett said she hoped to hold the trial this fall but Mangione's state trial, scheduled to begin Sept. 8, makes that "impossible."

“In my view it's simply impossible for us to be moving through the jury selection process in this case while the defendant and his counsel are fully engaged in the state trial,” Garnett said.

Mangione, wearing beige jail clothing, did not speak during Monday's hearing. His appearance was delayed about 20 minutes after he got stuck in an elevator with U.S. marshals.

Defense attorney Karen Friedman Agnifilo said New York State Supreme Court Justice Gregory Carro will hold firm to the Sept. 8 start.

Mangione has pleaded not guilty to federal charges that he stalked UnitedHealthcare CEO Brian Thompson before shooting and killing him in December 2024 in Midtown Manhattan. Mangione has also pleaded not guilty to state charges.

For the federal trial, hundreds of prospective jurors from Manhattan, the Bronx and New York City's northern suburbs will fill out questionnaires in December. Garnett said she would not post the questionnaire on the public docket until all prospective jurors finish filling it out, saying that the need for a fair and impartial jury overrides the customary expectation of public access to the document.

The defense said it might ask the judge to include additional questions depending on the outcome of Mangione's state trial.

The jury will be comprised of 12 jurors and six alternates.
