SANTA FE, New Mexico  - The trial of "Rust" chief weapons handler Hannah Gutierrez over the death of the film’s cinematographer starts on Wednesday, in a case likely to shape actor Alec Baldwin’s defense of his role in Hollywood's first on-set shooting fatality in nearly 30 years.

Rising-star cinematographer Halyna Hutchins died in 2021 after Gutierrez mistakenly loaded a live round into a reproduction Colt .45 revolver that Baldwin was rehearsing with on a movie set outside Santa Fe, New Mexico.
