(AP Photo/Yuki Iwamura, Pool)2025-12-02T05:04:12Z NEW YORK (AP) Luigi Mangione is due back in court on Tuesday for the second day of a hearing in his bid to bar New York prosecutors from using evidence that they say links him to last years killing of UnitedHealthcare CEO Brian Thompson.The pretrial hearing in Mangiones state murder case kicked off Monday with prosecutors playing surveillance videos of the Dec. 4, 2024, killing and security footage of his arrest five days later at a McDonalds in Pennsylvania.Mangione, 27, gripped a pen in his right hand, making a fist at times, as prosecutors played the audio of a 911 call from a McDonalds manager relaying concerns from customers that Mangione looked like the suspect in Thompsons death.Mangiones lawyers are asking Judge Gregory Carro to block prosecutors from showing or telling jurors about items seized from his backpack during his arrest, including a 9 mm handgun that prosecutors say matches the one used in the killing and a notebook in which they say Mangione described his intent to wack a health insurance executive. The defense contends the items should be excluded because police didnt have a warrant to search his backpack. They also want to suppress some statements Mangione made to law enforcement personnel, such as allegedly giving a false name, because officers started asking questions before telling him he had a right to remain silent. Mangione, the Ivy League-educated scion of a wealthy Maryland family, has pleaded not guilty to state and federal murder charges. The state charges carry the possibility of life in prison, while federal prosecutors are seeking the death penalty. Neither trial has been scheduled. The next hearing in the federal case is scheduled for Jan. 9. Stay up to date with the news and the best of AP by following our WhatsApp channel. Follow on Mangiones lawyers want to bar evidence from both cases, but this weeks hearing pertains only to the state case. Five witnesses testified on Monday, including a Pennsylvania prison officer who said Mangione told him that at the time of his arrest he had a backpack with foreign currency and a 3D-printed pistol. Another prison officer said his superintendent told him Mangione was being held under constant watch because the facility did not want an Epstein-style situation, referring to Jeffrey Epsteins 2019 jail suicide.More law enforcement officers are expected to take the witness stand on Tuesday.Surveillance video showed a masked gunman shooting Thompson from behind as the executive walked to a midtown Manhattan hotel for his companys annual investor conference. Prosecutors say delay, deny and depose were written on the ammunition, mimicking a phrase used to describe how insurers avoid paying claims.Mangione was arrested as he ate breakfast at a McDonalds in Altoona, Pennsylvania, about 230 miles (about 370 kilometers) west of Manhattan after the restaurants manager told a 911 dispatcher, I have a customer here that some other customers were suspicious of that he looks like the CEO shooter from New York.The manager told the dispatcher that she searched online for photos of the suspect that police disseminated. But, as Mangione sat in the restaurant, she said she could only see his eyebrows because he had a beanie pulled down close to his eyes and was wearing a medical face mask. On Monday, a few dozen Mangione supporters watched the hearing from the back of the courtroom.One wore a green T-shirt that said: Without a warrant, its not a search, its a violation. Another woman held a doll of the Luigi video game character and had a smaller figurine of him clipped to her purse.Court officials say the hearing could take more than a week.
