Key Evidence in Mangione Trial

ABC News Investigative Reporter Peter Charalambous talks about how the judge overseeing Luigi Mangione's state murder case ruled Monday that certain evidence seized from his backpack during a search at the Pennsylvania McDonald's where he was arrested must be suppressed, while evidence seized at the stationhouse in Altoona, Pennsylvania, including the alleged murder weapon, will be allowed. Peter, who is one of the hundreds of thousands of commuters stranded by the Long Island Railroad strike, has details and what this could mean for Mangione's defense.
