The assistant director of the film 'Rust', David Halls, admitted that he did not check all the bullets from the prop gun he himself passed to Alec Baldwin before the tragedy that led to the death of cameraman Halyna Hutchins.
The admission emerges from the report drawn up after the interrogations following the search warrant.
Investigators collected 600 items on the Rust set, including three guns and around 500 ammunition.
Also recovered was the bullet fired from the gun that killed the director of photography Halyna Hutchins and wounded the director Joel Souza.
"The facts are clear: the gun given to Alec Baldwin" was loaded with live bullets, and "we're trying to figure out how real ammunition got to the set," explains Santa Fe County Sheriff Adan Mendoza.
Authorities confirm Mendoza by hearing assistant director Dave Halls and gunsmith Hannah Gutierrez Reed.
Halls is the one who yelled 'cold gun', handing the gun to Baldwin.
Reed, on the other hand, is the 24-year-old in charge of gun safety on set.
