A judge cleared prosecutors to use Luigi Mangione’s diary and gun, found in his backpack, for use at his murder trial, but blocked other pieces of evidence from being used.

In the latest development in Mangione’s state murder trial over the killing of United Healthcare CEO Brian Thompson, Judge Gregory Carro gave a split ruling. The ruling allowed prosecutors to use a gun and handwritten diary found in Mangione’s backpack, rejecting the defense’s argument that they were obtained illegally. However, Carro bought the defense’s argument when it came to a gun magazine, cellphone, passport, wallet, and computer chip.
