Cinematographer Halyna Hutchins was killed in an incident involving a prop gun on the set of Rust, an Alec Baldwin film that was shooting in New Mexico on Thursday (Oct 21).
Baldwin fired the gun, according to the Santa Fe County Sheriff's office.
The film's director, Joel Souza, was also hit, and was receiving emergency care at a hospital in Santa Fe.
No charges have been filed.
Hutchins' death was confirmed by the Sheriff's office and by the International Cinematographers Guild, Local 600.
"We received the devastating news this evening, that one of our members, Halyna Hutchins, the Director of Photography on a production called Rust in New Mexico died from injuries sustained on the set," said John Lindley, the president of the guild, and Rebecca Rhine, the executive director, in a statement.
"The details are unclear at this moment, but we are working to learn more, and we support a full investigation into this tragic event.
"This is a terrible loss, and we mourn the passing of a member of our Guild's family."
The Santa Fe County Sheriff's office said it was investigating the incident, which was reported at 1.50pm Mountain Time at the Bonanza Creek Ranch, a popular filming location south of Santa Fe.
"The Santa Fe County sheriff's office confirms that two individuals were shot during filming of a scene on the set of the movie western Rust," the office said in a statement.
"According to investigators it appears that the scene being filmed involved the use of a prop firearm when it was discharged. Detectives are investigating how and what type of projectile was discharged."
Hutchins, 42, was transported by helicopter to University of New Mexico Hospital in Albuquerque, where she died.
Souza, 48, was taken by ambulance to Christus St. Vincent Regional Medical Center in Santa Fe.
Hutchins graduated from the American Film Institute in 2015, and had worked on several short films before shooting Archenemy, a 2020 feature starring Joe Manganiello.
She was named a "rising star" by American Cinematographer in 2019.
"She's a wonderful, positive, creative person that was so excited to be breaking through and making movies," said Michael Pessah, a cinematographer who was a friend of Hutchins'.
"She was really on the upswing."
Souza is writing and directing the Western, which also stars Frances Fisher, Jensen Ackles, Brady Noon and Travis Fimmel.
Albuquerque station KOB4's news helicopter photographed the incident, showing an old church set blocked off, and reported that set security confirmed it is on lockdown.
Baldwin is a co-producer on the film and plays infamous outlaw Rust, whose 13-year-old grandson is convicted of an accidental murder.
Ackles plays a US Marshal and Fimmel plays a bounty hunter who are on the pair's tail as Rust tries to break his grandson out of prison.
An unexpected bond forms between the outlaw and his estranged grandson as they go on the run. – Reuters
