A New Mexico detective on Wednesday said Hannah Gutierrez identified an ammunition box and bandoliers as hers, boosting the prosecution theory that the armorer brought live rounds onto the of set "Rust" where a cinematographer was fatally shot. Recent testimony during Gutierrez's involuntary manslaughter trial has seen prosecutors zero in on how six live rounds - strictly forbidden on movie sets - got onto the production where Halyna Hutchins was shot dead by actor Alec Baldwin on Oct. 21, 2021. Baldwin has pleaded not guilty to involuntary manslaughter.
