In connection with the shooting death of cinematographer Halyna Hutchins, prosecutors have accused a Rust film armorer of tampering with evidence, according to US media.
Involuntary manslaughter is what Hannah Gutierrez-Reed has already been accused of.
According to the prosecution, she will also be charged with "transferring narcotics to another person.".
According to the New York Times on Thursday, Ms. Gutierrez-Reed will enter a not guilty plea to the new charge. .
Prosecutors and Ms. Gutierrez-Reed have been contacted by the BBC for comment.
Prosecutors claim that on October 21, 2021, the day that Hutchins was killed, Ms. Gutierrez-Reed transferred drugs to a different individual in an effort to "prevent the apprehension, prosecution, or conviction of herself," according to court documents, according to Reuters.
Prosecutors stated last week that Ms. Gutierrez-Reed likely had a hangover on the day of the shooting because she drank alcohol and smoked marijuana in the evenings while the movie was being made.
Meanwhile, the attorney for Ms. Gutierrez-Reed claimed that the prosecution mishandled the case and engaged in "character assassination.". The involuntary manslaughter charge that has been brought against her has been the subject of a motion filed by her attorneys.
Just two weeks before Alec Baldwin's trial was scheduled to start, the prosecution dropped all charges against him. This latest court filing comes two months later.
After Hutchins was killed in New Mexico while Hutchins was being filmed for the Rust movie, he had been charged with two counts of involuntary manslaughter.
Kari Morrissey, the special prosecutor for New Mexico, claimed that "new facts were revealed" that necessitated additional research.
