NEW YORK — Luigi Mangione is scheduled to appear in court on Monday for significant hearings that will determine which pieces of evidence are admissible in his legal proceedings.

Last week, Mangione’s legal team requested that the judge restrict the discussion of certain evidence during the upcoming pre-trial hearing. They aim to prevent the session from becoming a “public mini trial,” which they argue could unfairly bias the jury against the accused.

Judge Gregory Carro has allocated several days, starting on Monday, to consider arguments about whether specific evidence should be excluded from the trial.

Mangione, who has denied all charges related to the murder of UnitedHealthcare CEO Brian Thompson, is seeking to block the prosecution from using a red notebook. Police claim they found this notebook in his backpack at the time of his arrest in Altoona, Pennsylvania.

The defense is also attempting to suppress Mangione’s statements made to police officers. They argue in court documents that law enforcement violated his constitutional rights by interrogating him without issuing Miranda warnings, infringing on the Fifth Amendment, and conducting an unlawful search of his belongings without a warrant, breaching the Fourth Amendment.

In a letter Tuesday, Mangione’s attorneys asked the judge to prevent prosecutors from introducing the contents of the notebook into evidence at the hearing, arguing “doing so would make their contents public and would irreparably prejudice Mr. Mangione at his multiple upcoming trials.” The defense also sought to keep witnesses from characterizing the writings as a “manifesto.”

Many of Mangione’s writings are already public and police and prosecutors have pointed to them as they work to establish motive.

“I finally feel confident about what I will do,” one entry in the notebook said. “The target is insurance. It checks every box.”

The district attorney’s office has said the Altoona Police Department acted lawfully when it seized Mangione’s property.

Defense attorneys said they intend to Altoona Police Cpl. Garrett Trent and Patrolman Randy Miller. They asked the judge to force prosecutors to disclose their full list of witnesses.
