Prosecutors: New analysis confirms Alec Baldwin pulled trigger in 'Rust' shooting

Prosecutors have received a new expert analysis of the gun used in the fatal shooting on the set of the film "Rust," which concludes that Alec Baldwin must have pulled or depressed the trigger. Baldwin has maintained that the gun fired accidentally. The analysis, based on replacement parts, contradicts Baldwin's claim and may lead to the refiling of charges against him. The gun analysis was disclosed by the defense attorney for Hannah Gutierrez-Reed, the weapons supervisor on the set, who is also facing charges in the case. The trial is scheduled to begin in December.
