SANTA FE, N.M. (AP) — A New Mexico judge plans to rule next week on a grand jury indictment against Alec Baldwin in the fatal shooting on the set of “Rust,” after hearing arguments Friday that the proceedings were unfair to the defendant.

The indictment in January charged Baldwin with involuntary manslaughter in the fatal shooting of cinematographer Halyna Hutchins on Oct. 21, 2021, at a movie ranch on the outskirts of Santa Fe.

Baldwin, a lead actor and co-producer on the Western, has pleaded not guilty to the charge, which carries a maximum sentence of 1.5 years in prison. His attorneys argued during the virtual hearing on Friday that the grand jury received a one-sided presentation in bad faith from prosecutors who steered jurors away from exculpatory evidence and witnesses.

During rehearsal, Baldwin was pointing a gun at cinematographer Halyna Hutchins when the revolver went off, killing Hutchins and injuring Joel Souza, the director. Baldwin has maintained that he pulled back the gun’s hammer, but not the trigger.
