Luigi Mangione’s federal death penalty trial could start before the end of the year

Either way, Garnett said, she expects jury selection to begin around Sept. 8. No trial date has been scheduled in Mangione’s parallel state murder case. Prosecutors previously said they anticipated the state trial to be first.

Garnett said she would issue a written schedule after looking at her calendar and reviewing notes of conversations she's had with the court’s jury coordinator.

The judge said she would rule at a later date on the defense's requests to prevent prosecutors from seeking the death penalty, throw out some charges and exclude certain evidence. Another pretrial conference is scheduled for Jan. 30.

Mangione’s lawyers contend that authorities prejudiced his case by turning his December 2024 arrest into a “Marvel movie” spectacle and by publicly declaring their desire to see him executed even before he was formally indicted.

At the same time, they are asking Garnett to throw out two of the four charges against him, including the murder by firearm charge that has enabled the government to seek the death penalty. They argue that it is legally flawed.

Federal prosecutors say Mangione’s lawyers are wrong on both fronts, countering that the murder charge is legally sufficient and that “pretrial publicity, even when intense” is hardly a constitutional crisis. Any concerns about public perceptions can be alleviated by carefully questioning prospective jurors about their knowledge of the case, prosecutors wrote in a court filing.

Mangione has pleaded not guilty to federal and state murder charges, which carry the possibility of life in prison.

Friday's hearing was Mangione’s first trip to Manhattan federal court since his April 25 arraignment.

A cause célèbre for people upset with the health insurance industry, Mangione again drew supporters to the courthouse. Some wore green clothing and carried signs such as “Free Luigi" and “No Death For Luigi Mangione."

Mangione, wearing a beige jail uniform, was attentive but didn’t speak once during the nearly three-hour proceeding. After entering the courtroom, he greeted his lead attorneys, Karen Friedman Agnifilo and Marc Agnifilo, with handshakes. He nodded along while reading documents, sometimes sipping from a plastic water bottle.

In addition to the death penalty issue, Garnett is weighing a defense request — similar to one in his state case — to bar the government from using certain items found in a backpack during his arrest. The defense argues that the search was illegal because police had not yet obtained a warrant.

Those items include a gun that police said matched the one used to kill Thompson and a notebook in which Mangione purportedly described his intent to “wack” a health insurance executive.

Garnett said she is not inclined to hold a separate hearing on the evidence issue like one last month that took three weeks in Mangione’s state murder case. The judge in that case said he won’t rule until May.

Prosecutors contend police were justified in searching the backpack to make sure there were no dangerous items and that the gun, notebook and other evidence would have eventually been found anyway.

Thompson, 50, was killed Dec. 4, 2024, as he walked to a Manhattan hotel for UnitedHealth Group’s annual investor conference. Surveillance video showed a masked gunman shooting him from behind. Police say “delay,” “deny” and “depose” were written on the ammunition, mimicking a phrase used to describe how insurers avoid paying claims.

Mangione, 27, the Ivy League-educated scion of a wealthy Maryland family, was arrested five days later at a McDonald’s in Altoona, Pennsylvania, about 230 miles (about 370 kilometers) west of Manhattan.

He's already had success paring down his state case. In September, a judge threw out state terrorism charges against him.

U.S. Attorney General Pam Bondi announced last year that she was directing federal prosecutors to seek the death penalty, declaring that capital punishment was warranted for a “premeditated, cold-blooded assassination that shocked America.”

Mangione’s lawyers argue that Bondi’s announcement, which she followed with Instagram posts and a TV appearance, showed the decision was “based on politics, not merit.” Her remarks tainted the grand jury process that resulted in his indictment a few weeks later, they said.
