Items found in Luigi Mangione's backpack when he was arrested in Pennsylvania last year include a handgun, a silencer, a magazine with bullets wrapped in underwear and a red notebook that an officer called a "manifesto."

The second week of a complex pretrial hearing kicked off Monday in Manhattan Criminal Court with a focus on the moments leading up to the 27-year-old's arrest in the murder of UnitedHealthcare CEO Brian Thompson.
