NEW YORK (AP) — A gun and notebook that prosecutors say link Luigi Mangione to the killing of UnitedHealthcare CEO Brian Thompson can be used as evidence at his murder trial, a judge ruled Monday, rejecting a defense argument that they were seized illegally, before a search warrant was obtained.Judge Gregory Carro’s decision, five months after he held a hearing to examine how police came upon the items, is a major win for prosecutors, enabling them to show the jury a possible murder weapon and evidence they say points to motive. That mirrors an earlier ruling in Mangione’s federal case.The judge said evidence found during an initial search of Mangione’s backpack during his arrest at a McDonald’s restaurant must be suppressed, including a gun ammunition magazine, cellphone, passport, wallet and computer chip.Mangione’s state murder trial is set to begin on Sept. 8. Jury selection for his federal trial, which involves stalking charges, is scheduled to start on Oct. 13, with opening statements and testimony beginning on Nov. 4. The state trial is expected to take four to six weeks.

Mangione, 28, has pleaded not guilty in both cases. He faces the possibility of life in prison if he is convicted in either one.
