District attorney says authorities haven't ruled out charges in deadly 'Rust' shooting

• Investigators are not ruling out charges in connection to the shooting on the set of "Rust."
• District Attorney Mary Carmack-Altwies said at a press conference that no one has been ruled out.
• Cinematographer Halyna Hutchins was killed last week after actor Alec Baldwin fired a prop gun.

Investigators said on Wednesday that they were not ruling out charges in connection to the shooting on the set of "Rust," in which actor Alec Baldwin fired a prop gun, killing cinematographer Halyna Hutchins and injuring director Joel Souza.

"All options are on the table at this point," New Mexico First Judicial District Attorney Mary Carmack-Altwies said about charges at a press conference on Wednesday. "No one has been ruled out."

Santa Fe Sheriff Adan Mendoza added that interviews with witnesses need to be sorted out.

Baldwin "is an active part of this investigation," Mendoza added.

Hutchins, 42, was fatally shot last week after Baldwin fired a firearm on set during rehearsal for a scene, according to affidavits released by the Santa Fe County Sheriff's Office.

The gun used was set up by the film's armorer, Hannah Gutierrez-Reed, before being given to Baldwin by assistant director Dave Halls, according to the affidavits.

Halls said "cold gun" as he handed it to Baldwin, according to the documents, which indicates that it contains no live rounds.

Director Joel Souza, 48, was also injured.

Mendoza said at Wednesday's press conference that the gun was loaded with a bullet, and that a lead projectile was recovered from Souza's shoulder.

After the deadly shooting, Baldwin tweeted that he was "fully cooperating with the police investigation."
