Police investigating the fatal shooting on the set of the Alec Baldwin film Rust have obtained a search warrant for the actor’s phone.
Cinematographer Halyna Hutchins died and director Joel Souza was injured in October, when Mr Baldwin was rehearsing drawing a prop gun.
Mr Baldwin, 63, has insisted he “didn’t pull the trigger”.
The warrant was issued by a Sante Fe court in New Mexico – the state where Rust was being filmed.
It says “there may be evidence on the phone” that could be “material and relevant to this investigation”.
Investigators asked to confiscate Mr Baldwin’s Apple iPhone that is “believed to be in his possession”.
They wanted to look at text messages, emails, web browser history and other information stored on the phone.
It comes two weeks after the star gave his first TV interview about the incident, in which he said he did not pull the trigger, but the gun went off anyway.
“I would never point a gun at anyone and pull a trigger at them. Never,” he told George Stephanopoulos of ABC News.
