 Actor Alec Baldwin was back in court yesterday in New Mexico for his involuntary manslaughter trial. As NPR's Mandalay Delbarco reports, prosecutors and defense lawyers focused on some of the evidence recovered from the crime scene in 2021. A Santa Fe crime scene technician was grilled about the guns and ammunition recovered from the set of the Western film Rust, including remnants of live bullets that were in the gun used by Alec Baldwin.
