An updated search warrant from the Santa Fe County Sheriff’s Office gives new details about the fatal shooting on the set ofRustthatkilled cinematographer Halyna Hutchins.

Explaining the typical protocol, Halls told deputies: “I check the barrel for obstructions, most of the time there’s no live fire, she (armorer Hannah Gutierrez-Reed) opens the hatch and spins the drum, and I say cold gun on set,” according to the warrant.

On the day of the incident, Halls said that Gutierrez-Reed showed him the loaded firearm after the crew returned from lunch, so that they could continue rehearsals. He told authorities he could only remember seeing three rounds in the gun, the affidavit states.

According to the warrant, he admitted that he should have checked each round, but he did not. He couldn’t remember if Gutierrez-Reed spun the drum.

He also advised that the round without the hole didn’t have a “cap” on it, and “was just the casing.” He maintained that the shooting was “not a deliberate act,” the warrant states.

In her interview with deputies, Gutierrez-Reed said that she had checked the rounds inside the firearm to make sure they were “dummies,” and not real bullets. When the crew broke for lunch, the guns were locked inside a safe on the prop truck, which few people had access to, she added.

Gutierrez-Reed also told authorities that no live ammunition was ever kept on set, according to the affidavit.

It has since been recovered from Souza’s shoulder.
