Law-enforcement officials in Santa Fe County, N.M., plan to hold a news conference Wednesday on their investigation into what happened last week when the actor Alec Baldwin was rehearsing on a film set with a gun he had been told did not contain live ammunition when it went off, killing the film’s cinematographer and wounding its director.
Here is an overview of some of what has emerged about the case:
The shooting happened during a rehearsal for a scene in “Rust,” a Western where Mr. Baldwin was playing an outlaw helping his grandson. Mr. Baldwin was holding a gun being used as a prop when it fired, striking the cinematographer, Halyna Hutchins, in the chest and the director, Joel Souza, in the shoulder. Ms. Hutchins, 42, was airlifted to a hospital in Albuquerque, where she died. Mr. Souza, 48, was taken by ambulance to a hospital in Santa Fe and was released on Friday.
In an affidavit accompanying a request for a search warrant, Detective Joel Cano the Santa Fe County Sheriff’s Office said that Dave Halls, an assistant director on the set, had gone outside and taken the gun off a cart, where it had been placed by the film’s armorer, Hannah Gutierrez-Reed. Mr. Halls handed it to Mr. Baldwin, who was rehearsing inside on the set of a church, according to the affidavit, and said it was a “cold gun,” indicating that it contained no live rounds and was safe for Mr. Baldwin to handle.
Mr. Baldwin has cooperated with the investigation, including going to the Santa Fe County Sheriff’s Office after the shooting to provide a statement and answer questions. No criminal charges against him or anyone else have been announced in the case.
When the shooting occurred Mr. Baldwin had been sitting in a wooden church pew, rehearsing a scene that involved “cross drawing” a revolver and pointing it toward the camera lens, Mr. Souza said, according to the affidavit. The director said he heard what “sounded like a whip and then loud pop” and then saw Ms. Hutchins grabbing her midsection and starting to stumble backward. Then he noticed he was bleeding from his shoulder.
The Santa Fe County district attorney said on Tuesday that she was not ruling out criminal charges in last week’s fatal shooting.
“We haven’t ruled out anything,” the district attorney, Mary Carmack-Altwies, said in a telephone interview. “Everything at this point, including criminal charges, is on the table.”
Ms. Carmack-Altwies said that the investigation was focusing on ballistics in an effort to determine what kind of round was in the gun that killed Halyna Hutchins, the cinematographer — and who had placed the ammunition in the gun.
“There were an enormous amount of bullets on this set, and we need to find out what kinds they were,” Ms. Carmack-Altwies said.
Detectives are still interviewing people who were on the set, Ms. Carmack-Altwies said. “It’s probably weeks, if not months, of follow-up investigation that we’re going to need to get to the point of charging.”
Ms. Carmack-Altwies took issue with descriptions of the firearm used in the incident as “prop-gun,” saying that the terminology, which is used in some of the court documents related to the case, could give the misleading impression that it was not a real gun.
“It was a legit gun,” she said, without naming specifically what kind of firearm was used. “It was an antique-era appropriate gun.”
Ms. Carmack-Altwies said that she was aware of news reports suggesting that crew members had used guns with live ammunition for target practice hours before the fatal shooting, but said that the reports were “unconfirmed.”
Ms. Carmack-Altwies described the case as one of the most challenging in Santa Fe County in recent memory.
“We have complex cases all the time,” she said. “But this kind of complex case, with these kinds of prominent people, no.”
