Luigi Mangione’s federal case was pushed back from the fall to early 2027 on Monday after a judge found the original timeline could conflict with his state murder case.

At a brief hearing, Manhattan Federal Judge Margaret Garnett adjourned the federal trial to Jan. 5, saying Nov. 4 was no longer feasible, as Mangione may still be on trial across the street in a prosecution being handled by Manhattan District Attorney Alvin Bragg. Jury selection starts in that case Sept. 8.

“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 occupied,” the judge said.

Referencing the “dueling prosecutions,” Karen Friedman-Agnifilo, leading Mangione’s defense, told the court that his lawyers may have last-minute additions to the jury selection questionnaire, contingent on the outcome of the state trial.

“We might ask the court to include other questions,” the attorney said, “depending on how that goes.”

Mangione, of Maryland, is accused of fatally shooting Thompson outside the Hilton hotel in Midtown on Dec. 4, 2024, in a violent protest of the U.S. health insurance industry.

The 28-year-old faces federal stalking offenses alleging he tracked the healthcare executive for weeks in late 2024. He was originally charged in the case with murder through use of a firearm — a capital offense — but Garnett dismissed the top count in January, finding it was legally unsupported by the other charges.

In his state case, Mangione is charged with second-degree murder and related charges carrying 25 years to life in prison.

Mangione wore khaki-colored prison clothing and was not shackled at Monday’s brief proceeding, which lasted about 20 minutes. He was seen quietly conferring with his lawyers and appeared focused.
