THE Santa Fe County district attorney said Tuesday that she was not ruling out criminal charges in last week’s fatal shooting on a film set in the U.S.

Actor Alec Baldwin was rehearsing with a gun that he had been told did not contain live ammunition when it went off, killing the film’s cinematographer and wounding its director.

“We haven’t ruled out anything,” the district attorney, Mary Carmack-Altwies, said in a telephone interview.

“Everything at this point, including criminal charges, is on the table.”

Carmack-Altwies said that the investigation was focusing on ballistics in an effort to determine what kind of round was in the gun that killed Halyna Hutchins, the cinematographer — and on who had placed the ammunition in the gun.

“There were an enormous amount of bullets on this set, and we need to find out what kinds they were,” Carmack-Altwies said.

Detectives from the Santa Fe County Sheriff’s Office are proceeding carefully with the investigation, she said, citing the large number of witnesses and the need to methodically collect ballistics and forensics evidence.

The shooting occurred last Thursday on the set of a church where Baldwin was rehearsing a scene for “Rust, a Western” where he plays an outlaw.
