Prosecutor Says Manslaughter Case Against Alec Baldwin Should Be Revived

A prosecutor who oversaw the involuntary manslaughter case against Alec Baldwin has asked a judge in New Mexico to reconsider her dismissal of the charge during the trial.

The judge tossed out the case in July after finding that the state had withheld evidence that could have shed light on how live rounds got onto a film set where a cinematographer, Halyna Hutchins, was fatally shot. The judge dismissed the case with prejudice, meaning that it could not be refiled, ending the prosecution of Mr. Baldwin.

But in court papers filed on Friday, Kari T. Morrissey, the special prosecutor, sought to persuade Judge Mary Marlowe Sommer to change her mind, arguing that the evidence in question — a batch of rounds brought to law enforcement this year — was irrelevant to whether Mr. Baldwin was criminally culpable for pointing the gun on set that day.

“Nothing about the details of how the live rounds were introduced to the set is relevant or material to the charges against Mr. Baldwin,” Ms. Morrissey wrote in the court papers, later writing, “there was no cover-up because there was nothing to cover up.”

The dramatic dismissal of the case against Mr. Baldwin prompted the movie’s armorer, Hannah Gutierrez-Reed, to ask for a new trial; she was convicted of involuntary manslaughter in March and sentenced to 18 months in prison.

It was the third day of Mr. Baldwin’s manslaughter trial at the Santa Fe County District Courthouse when his lawyers sought the dismissal of the case over the state’s failure to provide it with live ammunition that came from a man named Troy Teske, a friend of Ms. Gutierrez-Reed’s stepfather, Thell Reed, who is a well-known Hollywood armorer.
