The armorer in charge of weaponry used in the filming of Western Rust issued the prop supplier, alleging that his company distributed live ammunition on the scene where actor Alec Baldwin allegedly fired a round that killed cinematographer Halyna Hutchins.

According to a lawsuit filed in New Mexico state court on Thursday AEDT, Hannah Gutierrez Reed, 24, issued prop provider Seth Kenney and his company, PDQ Arm and Prop LLC, for undisclosed damages.

Kenney was unavailable for comment. In a December interview with ABC News, Kenney refuted that his company provided live rounds on set.

"The unexpected addition of live rounds to the set, combined with the rushed and chaotic atmosphere, created the ideal conditions for a safety incident," the lawsuit alleges.

Authorities in New Mexico are investigating the October 21 incident, which stunned show business by killing the rising star cinematographer and injuring the film's director, Joel Souza.

Reed's suit alleges that she recalls loading the rifle with rounds labeled as dummy ammo and shaking the box to simulate the inert bullets' trademark jingling sound.

The complaint stated that "to the best of Hannah's knowledge, the gun was now loaded with six dummy rounds."

Additionally, the claim alleges that she relinquished control of the gun for 15 minutes before the shooting because COVID rules prohibited her from entering the church where the shooting occurred. Baldwin was not filmed during the shooting since he rehearsed for a sequence that would be shot later.

"The ammunition was misrepresented as containing only dummy rounds when it actually contained both dummy and live rounds," the suit stated. "Defendants distributed boxes of ammunition to the I production purporting to contain dummy rounds but actually containing a mixture of dummy and live ammunition."

Baldwin informed ABC News that he did not pull the trigger, explaining that the Colt revolver fired while cocking the gun and rehearsing camera angles with Hutchins.

The Santa Fe County Sheriff's Office, investigating the death, has stated that it is too early to tell whether charges will be made. According to investigators, there was "some complacency" in the way guns were handled on set.
