Judge rules gun and notebook admissible as evidence in Luigi Mangione murder trial while suppressing other items from McDonald's arrest

A New York judge ruled Monday that a gun and notebook found in Luigi Mangione's backpack at a police station are admissible as evidence in his state murder trial for killing UnitedHealthcare CEO Brian Thompson, but suppressed items seized during an initial warrantless search at a Pennsylvania McDonald's during his arrest. The judge found the McDonald's search violated constitutional protections, while the subsequent stationhouse inventory was valid.
