Defense seeks to suppress evidence in UHC CEO killing

Luigi Mangione returned to court Dec. 2 as his defense sought to suppress contested items — including a gun and handwritten “notes to self” — in the UnitedHealthcare CEO killing case, while prosecutors point to bullets found in his bag that they say convinced police he was the suspect. A pretrial hearing day was postponed after Mangione fell ill, and no immediate ruling on the evidentiary disputes was reported as proceedings are set to resume later.
