Ms. Gutierrez-Reed told investigators that the guns and ammunition used on the “Rust” set had been supplied by Mr. Kenney, according to the affidavit.
On Oct. 27, as the police executed a search warrant on the set, Mr. Kenney told investigators that he had provided the production with dummy rounds and blanks that came from a company called Starline Brass, the affidavit said. Two days later, it said, Mr. Kenney called back to say “he may know where the live rounds came from.”
In that call, Mr. Kenney told the police that a couple of years ago he had received “reloaded ammunition” from a friend, the affidavit said. “Reloaded ammunition” can refer to ammunition that has been reconstituted from the brass casing of a fired round by adding a new bullet, primer and powder, according to Clay Van Sickle, a movie industry armorer.
Mr. Kenney declined to comment in response to a phone call.
Mr. Kenney told investigators that in this case, he believed the ammunition had been reloaded because the cartridge of a live round had the Starline Brass logo on it, and Starline Brass “only sells components of ammunition, and not live ammunition, and therefore it had to be a reloaded round.”
Starline, which is based in Sedalia, Mo., did not immediately respond to requests for comment.
Another lead on where the live round might have originated came from Ms. Gutierrez-Reed’s father, Thell Reed, a weapons expert who has worked and consulted on a number of films.
The detective said that she received a statement from Mr. Reed in mid-November saying that he had worked with Mr. Kenney on another set in August or September where the actors were trained “for live fire with firearms, conducted on a firearms range,” and that Mr. Kenney had asked him to bring extra live ammunition in case they ran out.
