 Prosecutor Erlinda Johnson told the jury. The evidence will show that someone who played make-believe with a real gun and violated the cardinal rules of firearm safety is the defendant, Alexander Baldwin. A defense lawyer told jurors Baldwin committed no crime. The actor was holding a prop gun that went off killing a 42-year-old cinematographer on the set of the low-budget Western movie Rust in 2021 on a remote ranch in New Mexico. Jim Crisula, CBS News.
