The latest Luigi Mangione case update centers on a major shift in his New York state murder case. Mangione’s lawyers withdrew plans to use a psychiatric defense tied to the killing of UnitedHealthcare CEO Brian Thompson.
Mangione has pleaded not guilty in both state and federal cases. He remains accused of killing Thompson outside a Manhattan hotel in December 2024.
Luigi Mangione Case Update: Defense Changes Course
Mangione’s legal team recently told the court it would not pursue an “extreme emotional disturbance” defense in the upcoming state trial. The reversal came one day after the defense signaled it would use that argument.
Under New York law, that defense would not mean a defendant is found not guilty. Instead, it can reduce a murder conviction to manslaughter if a jury accepts it.
Judge Gregory Carro had ordered the defense to provide prosecutors with information supporting the claim. Soon after, defense attorney Karen Friedman Agnifilo withdrew the notice.
The decision adds uncertainty to the defense strategy. However, it does not change Mangione’s not guilty plea.
State Trial Remains Set for September
Mangione’s state trial is scheduled to begin Sept. 8, 2026, in New York. He faces charges connected to Thompson’s killing, including second-degree murder.
A recent court hearing was delayed after prosecutors failed to complete the paperwork needed to bring Mangione from federal custody to court. Prosecutors acknowledged the mistake, and the hearing moved forward the next day.
The case has drawn national attention because of Thompson’s role as a major health insurance executive. It has also sparked public debate about health care, corporate power and the criminal justice system.
Still, the court case remains focused on the criminal charges and evidence.
Evidence Rulings Shape the Case
In May, Judge Carro ruled that prosecutors may use a gun and notebook found in Mangione’s backpack as evidence in the state case. Prosecutors say the items link Mangione to Thompson’s killing.
The judge also found that some items from an earlier search of the backpack must be suppressed. Those items included a gun magazine, cellphone, passport, wallet and computer chip.
That split ruling gave both sides partial victories. Prosecutors kept key evidence, while the defense succeeded in excluding some material from the initial search.
Federal court has also allowed backpack evidence in the separate federal case.
Federal Case Also Moving Forward
Mangione also faces federal charges tied to the same killing. He has pleaded not guilty in that case as well.
ABC News and Court TV reported in April that the federal trial was pushed to January 2027. Jury selection is expected to begin Jan. 5, with opening statements scheduled for Jan. 25.
A federal judge previously removed death penalty-related charges from the case. As a result, Mangione no longer faces capital punishment in federal court.
However, he could still face life in prison if convicted in either the state or federal case.
What Comes Next
The next phase of the Luigi Mangione case will likely focus on trial preparation, evidence arguments and jury selection. The withdrawn psychiatric defense may also affect how lawyers present the case in September.
For now, Mangione remains presumed innocent unless proven guilty in court. The upcoming state trial will determine how prosecutors and defense attorneys frame one of the most closely watched criminal cases in the country.
