Luigi Mangione complained about double jeopardy in a courtroom outburst on Friday about the prospect of back-to-back trials in the shooting death of UnitedHealthcare CEO Brian Thompson.

As he was escorted out of a New York courtroom, he was heard saying, “It’s the same trial twice. One plus one is two. Double jeopardy by any common sense.”

Prior to his outburst, Mangione was quietly sitting at the defense table throughout the proceedings.

His attorney, Karen Friedman Agnifilo, also complained on Friday that double jeopardy was being used as a “weapon” against her client.

The comment came after a brief hearing regarding the scheduling of his state and federal trials in the shooting death of Thompson.

Following a lengthy discussion with prosecutors and defense lawyers, Judge Gregory Carro said the state trial would be on June 8, but could be moved to Sept. 8 if an appeal delays the federal trial.

Agnifilo protested, saying her client was being put in an “untenable” situation and that the defense would not be ready on June 8.

“Mr. Mangione is being put in an untenable situation,” Agnifilo said. “This is a tug-of-war between two different prosecution offices.”

Despite the defense’s assertion that it would not be ready for June 8, as they will be consumed with preparing for the federal trial, Judge Gregory Carro told Agnifilo, “You’ve done a great job. Be ready June 8.”

The state trial was initially set to take place before the federal trial, something that the family of the late UnitedHealthcare CEO Brian Thompson had requested. Jury selection for the federal trial has been set for Sept. 8, which will be followed by opening statements and testimony on Oct. 13, according to The Associated Press.

“It appears the federal government has reneged on its agreement to let the state, which has done most of the work in this case, go first,” Carro said Friday, the AP reported. The outlet noted that scheduling the state trial first could help the prosecution avoid double jeopardy issues.

Mangione has pleaded not guilty to federal and state charges, which carry the possibility of a life sentence. He was facing a terrorism charge at the state level, but Carro threw out the charge in September.

On Dec. 4, 2024, Mangione allegedly shot Thompson as he was walking into a midtown Manhattan hotel for a UnitedHealth Group conference. Surveillance video showed a masked gunman, who is believed to be Mangione, shooting him. Police said the words “delay,” “deny” and “depose” were written on Mangione’s ammunition, which the AP notes is close to a phrase used to describe how insurers avoid paying claims.
