Gene Maddaus Senior Media Writer Hannah Gutierrez Reed, the armorer on the ill-fated Western film “Rust,” was convicted on Wednesday of involuntary manslaughter in the death of the film’s cinematographer. Jurors returned a verdict after less than three hours of deliberations on Wednesday afternoon, following two weeks of testimony about safety lapses on set. Gutierrez Reed was acquitted of a separate charge of tampering with evidence.
