Criminal charges had not been ruled out for the investigation into the fatal shooting on the set of Rust, a Western whose star Alec Baldwin killed cinematographer Halyna Hutchins after firing a gun on set, Santa Fe County sheriff Adan Mendoza said today (Oct. 27). Assistant director Dave Halls reportedly told Baldwin the revolver was “cold,” meaning it did not have live rounds, before he shot Hutchins and director Joel Souza, who survived.
