60 Minutes · Breaking down what can and can't be used as evidence in Luigi Mangione's state murder trial

1. 1. A judge ruled that a 3D-printed gun and a notebook with writings critical of health insurance CEOs are admissible evidence in Luigi Mangione's state murder trial.
2. 2. Items seized during Mangione's arrest at a Pennsylvania McDonald's, including a gun magazine, passport, wallet, cell phone, and computer chip, were excluded due to an improper warrantless search.
3. 3. Statements Mangione made to police before 9:47 a.m. are admissible because he was not in custody and a reasonable person would have felt free to leave.
4. 4. In the federal case against Mangione, all evidence is admissible, contrasting with the state court's split ruling.
