The gun supervisor for the film "Rust," in which a crew member was murdered when a pistol carried by actor Alec Baldwin went off during a rehearsal, claims she has no idea where the real bullet came from.

Hannah Gutierrez was responding to "untruths told to the media," according to a statement released Thursday night by her attorneys to NBC News.

"Safety is Hannah's number one priority on set," reads the statement from attorneys Jason Bowles and Robert Gorence. "Ultimately this set would never have been compromised if live ammo were not introduced. Hannah has no idea where the live rounds came from."

CNN reached out to Gutierrez's attorneys and the "Rust" production office for comment on Friday morning.

Two crew workers from the upcoming Nicolas Cage picture "The Old Way," which Gutierrez admitted in a podcast was her only previous film experience as an armorer, told CNN that she was irresponsible on that movie.

But, according to Gutierrez's attorneys, the firearms on "Rust" were locked up every night and during lunch, and Gutierrez had no clue how the live bullet that killed the director of photography Halyna Hutchins and wounded director Joel Souza arrived on set.

"Hannah and the prop master gained control over the guns and she never witnessed anyone shoot live rounds with these guns and nor would be permit that," the statement said, according to NBC.

Santa Fe County District Attorney Mary Carmack-Altwies told CNN this week that the investigation into the tragic "Rust" event is extensive and complex, and any claims of someone discharging live bullets with the firearms have not been proven. In this case, no one has been charged.
