A sheriff in New Mexico released a video on Monday that showed actor Alec Baldwin practicing with an old-west-style revolver on the set of the film "Rust" before the gun went off in his palm, killing a cinematographer.

Sheriff Adan Mendoza of Santa Fe County also released crime scene images and videotaped interviews with "Rust," cast members, including Baldwin, but said a formal decision on criminal charges would be contingent on additional forensic work.

"Various components of the investigation remain outstanding, including FBI firearm and ballistic forensics along with DNA and latent fingerprint analysis, (coroner's) findings and the analysis of Mr. Alec Baldwin's phone data extracted by Suffolk County Sheriff's investigators," Mendoza said in a written statement.

New Mexico penalized Rust Movie Productions for the highest amount allowed, $137,000, for what it described as "willful" safety failures that resulted in cinematographer Halyna Hutchins' death.

In October, Hutchins, 42, was killed when the handgun Baldwin was holding discharged a live cartridge, striking her in the chest and lodging in director Joel Souza's shoulder. Souza recovered from his gunshot wound.

Baldwin has disputed guilt for Hutchins' death, claiming that live ammunition should never have been permitted on the Western film set at New Mexico's Bonanza Creek Ranch.

Baldwin appears in costume as an old west gunslinger and practices with what seems to be the gun that went off in his hand, murdering Halyna, in the film released on Monday.

Separate camera footage shows the actor being questioned by police officers at both the shooting scene and a police station.

Baldwin, who worked on the film as a producer, has been mentioned in various lawsuits related to Hutchins' death, including one brought by her husband, Matthew.

In court documents, the 64-year-old actor argues that an indemnification clause in his contract protects him from personal accountability.
