Luigi Mangione, the accused assassin of United HealthCare CEO Brian Thompson, will be back in a Manhattan courtroom on Monday for a pre-trial hearing just days before the one-year anniversary of the killing.

The hearing will take place before Judge Gregory Carro at New York County Criminal Courthouse on Dec. 1 in advance of Mangione's state murder trial. He is also being prosecuted for the shooting in federal court.

During Monday's hearing, ABC News reported, Mangione's attorneys are expected to argue against certain evidence that prosecutors for Manhattan District Attorney Alvin Bragg intend to present before the jury. The evidence includes writing in a notebook Mangione kept, excerpts of which have already gone public, which seemed to establish an apparent motive for the assassination.
