Santa Fe County District Attorney Mary Carmack-Altwies is speaking out about last week's fatal movie-set shooting.
On Thursday, actor Alec Baldwin discharged a firearm – he was told was "cold" or unloaded – while rehearsing for the upcoming film "Rust" on the set near Santa Fe, New Mexico. It ultimately resulted in the death of cinematographer Halyna Hutchins.
Director Joel Souza was wounded by the projectile but has since been released from a hospital.
Carmack-Altwies recently spoke with The New York Times, explaining why she takes issue with the term "prop gun," which has been used in connection with the incident, calling it misleading.
"It was a legit gun," she told the outlet. "It was an antique, era-appropriate gun."
Carmack-Altwies did not offer any additional information on the type of gun, but three revolvers were included on an inventory list of items collected by authorities from the set of the western-genre film amid their investigation.
Gun safety expert Tom Gresham recently told Fox News that the term "prop gun" was "without meaning."
"A prop gun can be a real firearm that's just used as a prop in a movie. People are making the mistake of thinking ‘prop gun’ means a gun that doesn't fire. That's not true at all," he explained. "A prop gun is just a gun that's used in a movie that could be a live gun, or it could be an inert gun. So there's a lot of misunderstanding on that and people who think they know what that term means or getting confused by it."
Furthermore, weapons armorer Bryan Carpenter also told Fox News the term "prop gun" refers to "a gun that's made out of rubber."
"Either soft rubber or hard rubber, and/or plastic, and they're used when you don't need a real gun. In other words, it's not going to be firing blanks," he said. "You use them for stunt performers who are going to be coming through a window, or the gun's going to go flying across the floor in a scene, or they're having a fight scene where they're going to be hitting each other with the gun, or for rehearsals where a gun is not needed."
In her discussion with the Times, Carmack-Altwies noted that there was a large number of bullets on the set of the movie.
"There were an enormous amount of bullets on this set, and we need to find out what kinds they were," she said.
The inventory list indicated that they collected several cases of ammunition – including multiple boxes and a fanny pack – as well as loose items. The inventory did not specify the exact amount of ammunition that was collected.
The district attorney also said that the filing of criminal charges is a possibility as the investigation continues.
"We haven’t ruled out anything," she explained. "Everything at this point, including criminal charges, is on the table."
