Alec Baldwin was unaware that the prop gun which killed one and seriously injured another on the set of his new movie Rust contained live rounds, according to reports.
On Thursday, Santa Fe authorities confirmed that it was the 63-year-old actor who fired the stunt gun.
Alec is said to have cocked and fired the gun on set of the Western movie, shooting the film’s director and cinematographer.
Rust's Director of Photography Halyna Hutchins was airlifted from the set after being hit in the stomach at the Bonanza Creek Ranch.
The 42-year-old was rushed to the University of New Mexico Hospital in Albuquerque, but later died.
Director Joel Souza, 48, was also shot according to the Santa Fe County sheriff. He remains in intensive care.
Police are still investigating the incident at the popular filming location and no charges have been filed.
Local newspaper, Santa Fe New Mexican reported that Alec was seen in tears outside the local sheriff's office on Thursday.
The set of the movie was reportedly locked down after the gunfire.
A representative for the film told Deadline: "There was an accident today on the New Mexico set of Rust involving the misfire of a prop gun with blanks. Two crew members have been taken to the hospital and are receiving care. Production has been halted for the time being."
Following the confirmation of Halyna's death, Cinematographers Guild’s National President, John Lindley, and National Executive Director, Rebecca Rhine released a statement.
It read: "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.
"The details are unclear at this moment, but we are working to learn more, and we support a full investigation into this tragic event,” added the guild executives.
"This is a terrible loss, and we mourn the passing of a member of our Guild’s family."
Alec is a co-producer of the film and plays its outlaw namesake, who attempts to free his 13-year-old grandson from prison after he is convicted of an accidental murder.
