Two weeks ago, reports emerged about a shooting on the set of the film Rust.
As details started trickling in, it was confirmed that a prop gun had been discharged, killing the film's director of photography, Halyna Hutchins, and wounding the movie's director, Joel Souza.
It was later announced that the producer and star of the film, Alec Baldwin, was the one who fired the gun.
In the days since, further details have come out about the incident, the prop gun, and those involved.
Here's everything we know about the fatal shooting on the set of Rust.
What happened?
On October 21, Alec Baldwin was in character, rehearsing a scene for his new Western film, Rust, that involved him shooting a gun on set.
The crew had just returned from lunch, and according to an affidavit obtained by Insider, assistant director David Halls told police that he did not check all the rounds in the barrel of the prop gun when he returned to set.
Halls told police that when the film's armourer Hannah Gutierrez-Reed "showed him" the prop gun used by Baldwin, "before continuing rehearsal, he could only remember seeing three rounds".
Halls "advised he should have checked all of them, but didn't and couldn't recall" if Gutierrez-Reed "spun the drum" of the gun, before handing it to Baldwin and yelling "cold gun!" - an industry term meaning a weapon is not loaded with ammunition, including blanks.
