Alec Baldwin has made his first public statement since a fatal shooting on the set of his new film, as the 911 call made from the set was released.
"There are no words to convey my shock and sadness regarding the tragic accident that took the life of Halyna Hutchins, a wife, mother and deeply admired colleague of ours," Baldwin tweeted on Friday.
"I'm fully cooperating with the police investigation to address how this tragedy occurred and I am in touch with her husband, offering my support to him and his family. My heart is broken for her husband, their son, and all who knew and loved Halyna."
The actor was in New Mexico filming Rust which he's starring in and producing. Baldwin discharged a prop firearm on the set that resulted in the death of Halyna Hutchins, 42, the film's director of photography, according to investigators.
A spokesperson for Mr Baldwin said a prop gun with blanks misfired.
Details of the 911 call by a crew member have since been released.
"Two people have been accidentally shot on a movie set by a prop gun on Bonanza Creek Ranch. We need help immediately," the crew member said.
"Stay on the phone with me, we're going to get some help. Don't hang up, hold on one more second," the operator replies.

"It sounds like someone else is calling for ambulances. We need some help. Director and our cameraman have been shot," the crew member said again.
A spokesman for the Santa Fe County sheriff said detectives were investigating what type of projectile was discharged and how. No immediate charges were filed.
Mr Baldwin was performing at the time of the shooting, the sheriff's office said. It was unclear how many rounds were fired, and little was known about the weapon.
Director Joel Souza, 48, was also injured in the incident and transported to Christus St. Vincent's Regional Medical Centre by ambulance for care.
The Santa Fe County Sheriff's Office said the investigation "remains open and active" and no charges have been filed.
"According to investigators, it appears that the scene being filmed involved the use of a prop firearm when it was discharged," a statement from law enforcement read.
"Detectives are investigating how and what type of projectile was discharged."
Production accidents, despite safety measures, have happened before. While filming the movie The Crow in 1993, actor Brandon Lee, the son of Bruce Lee, was killed in a prop gun shooting accident.
Even blank ammunition can be deadly if fired at close range.
In 1984, actor John-Eric Hexum was playing around with a gun on the set of "Cover Up: Golden Opportunity" and died after putting the gun to his head and pulling the trigger.
