 In the middle of actor Alec Baldwin's trial for involuntary manslaughter on Friday, Judge Mary Marlowe Sommer ruled that prosecutors had withheld evidence from the actor and his lawyers. She dismissed the case and said new charges cannot be filed. It was a stunning end to a long-delayed trial over the shooting death of cinematographer Helena Hutchins. That shooting was on the New Mexico set of Baldwin's movie Rust in late 2021.
