The judge overseeing the state murder trial of Luigi Mangione, the man accused of gunning down UnitedHealthcare CEO Brian Thompson, ruled that prosecutors can use a gun and a notebook as evidence, effectively rejecting the defense's argument that those items were seized illegally.

However, Judge Gregory Carro said prosecutors cannot admit other items found in Mangione’s backpack when he was arrested at a McDonald’s in Pennsylvania, including a loaded magazine, a passport and a wallet.
