SANTA FE, N.M. —

Actor Alec Baldwin fired a prop gun on a movie set and killed the cinematographer, authorities said. The director of the Western being filmed was also wounded, and authorities are investigating what happened.

Halyna Hutchins, cinematographer on the movie “Rust,” and director Joel Souza were shot Thursday on the rustic film set in the desert on the southern outskirts of Santa Fe, Santa Fe County Sheriff’s officials said.

A spokesperson for Baldwin said there was an accident on the set involving the misfire of a prop gun with blanks, though a charge without a metal projectile is unlikely to kill at a moderate distance. Sheriff’s spokesman Juan Rios said detectives were investigating how and what type of projectile was discharged.

Santa Fe County deputies say they responded to Bonanza Creek Ranch where the movie was being filmed after receiving a 911 call saying someone had been shot.

Hutchins, 42, died from her injuries, according to the Santa Fe County Sheriff's Office.

Souza, 48, was taken to a hospital for his injuries.

Deputies are investigating how and what type of projectile was discharged from the prop gun. No charges have been filed.

The Santa Fe New Mexican reported Baldwin was seen Thursday outside the sheriff’s office in tears, but attempts to get comment from him were unsuccessful.

Filming for “Rust” was set to continue into early November, according to a news release from the New Mexico Film Office.

The movie is about a 13-year-old boy who is left to fend for himself and his younger brother following the death of their parents in 1880s' Kansas, according to the Internet Movie Database website. The teen goes on the run with his long-estranged grandfather (played by Baldwin) after the boy is sentenced to hang for the accidental killing of a local rancher.

The film also stars Jensen Ackles and Travis Fimmel.

In 2016, a man stabbed his co-worker at this same filming location.

That incident happened in April of 2016 when the victim said he was arguing with Jame Ruelas.

He said Ruelas called him to an empty room and attacked him with a carving knife.
