The District Attorney’s Office of the District of Santa Fe, New Mexico, has not ruled out criminal charges following the incident on the movie “Rest” set in which actor Alec Baldwin accidentally shot and killed a camera director.

“We’re not ruling out anything,” District Attorney Mary Carmack-Altwies told the New York Times. “At the moment, everything, including criminal complaints, is on the table.” However, according to Carmack-Altwies, the investigation into the incident primarily focuses on the ballistics investigation to determine what type of ammunition caused the death of Halyna Hutchins.

“There were a huge amount of bullets on this set, and we need to know what types were used,” said Carmack-Altwies. In addition, police officers reportedly seized three revolvers, empty bullet casings and a supply of ammunition (boxed, loose, and some even in a pouch bag) on the set.

Carmack-Altwies also disagrees with using the word ‘prop gun’ (roughly translated: ‘prop’ or ‘fake weapon’) when referring to descriptions of the incident because “it might give the impression that it is not about a real weapon. That was it: an antique but real gun.”

The investigation also focuses on the question of who placed the ammunition in the weapon. According to witness statements, assistant director Dave Halls grabbed the gun from a cart next to the building where the shooting was taking place, where Hannah Gutierrez-Reed had placed it, the film’s weapons expert.

Halls then gave the gun to actor Alec Baldwin stating that it was a “cold gun”. Baldwin would then have practised the scene and aimed the weapon at the camera, after which the fatal shot was fired. As a result, Halyna Hutchins was fatally shot in the chest and director Joel Souza in the shoulder.

Police are still interrogating the many people on set. “It will probably take weeks, maybe even months of further investigation before we decide if and who to charge,” Carmack-Altwies said.
