Luigi Mangione, the man accused of gunning down a UnitedHealthcare executive outside a Manhattan hotel, arrived at state court on Monday for a series of high-stakes hearings on the admissibility of key pieces of evidence at his murder trial.

Mangione, 27, was arrested in December 2024 and charged with fatally shooting UnitedHealthcare CEO Brian Thompson on a sidewalk in Midtown Manhattan. Public officials condemned the shocking assassination. Mangione became a folk hero to some Americans who decry steep healthcare costs.

He has pleaded not guilty to murder and other charges and is expected to face trial next year. Mangione has pleaded not guilty in a separate federal case where prosecutors plan to seek the death penalty.

Mangione wore a grey suit and a white shirt with a red checkered pattern and said nothing as officers removed his handcuffs at the defense table.

Several supporters of Mangione appeared outside the courthouse before the hearing, including one dressed as the villain from the video game Super Mario Bros., bearing a sign that said, “When patients die, profits rise,” and a woman with a “Free Luigi” sash.

Defense Seeks To Block Evidence

The hearings before Judge Gregory Carro could last the week and feature testimony from witnesses involved in Mangione’s arrest in Pennsylvania, where Mangione’s lawyers say he was illegally searched and questioned.

The defense lawyers are seeking to block prosecutors from presenting evidence police say was found in Mangione’s backpack, including a 3D-printed gun, a silencer, electronic devices and journal writings that appear to implicate him in the killing.

Mangione’s lawyers are also seeking to suppress statements he gave to police during his arrest, saying police did not give Mangione proper notice of his legal rights.

Prosecutors with the office of Manhattan District Attorney Alvin Bragg have opposed Mangione’s requests to suppress the evidence and denied his claims that he was illegally searched and questioned.

Mangione could face life in prison if convicted of murder in the second degree, which is defined as an intentional killing. He also faces seven counts of criminal possession of a weapon and one count of possessing a false identification.

Carro dismissed two terrorism counts against Mangione in September, finding prosecutors had not presented enough evidence that Mangione intended to intimidate health insurance workers or influence government policy.

Trial dates have not been set in either the state or federal cases. Mangione has been held in federal custody in Brooklyn since his arrest.
