She has pleaded not guilty to that charge and a second charge of tampering with evidence in Hutchins’ death. “Rust” weapons supervisor Hannah Gutierrez-Reed also has been charged with involuntary manslaughter, with a jury trial scheduled to start Feb. Weapons forensics expert Michael Haag, a Mississippi-based movie armorer and a detective with the Santa Fe County Sheriff’s Office also testified.

The grand jury heard from a “Rust” crew member who was a few feet (meters) from the fatal shooting and another who walked off the set before the shooting in protest of working conditions.
