Baldwin had been rehearsing on the set of the upcoming Western, Rust, when the prop gun he was holding accidentally discharged, killing Hutchins and wounding director Joel Souza.
The film’s armourer, Hannah Gutierrez Reed, will also be charged.
Neither party has commented on the charges.
Santa Fe’s District Attorney Mary Carmack-Altwies announced that charges would be filed against Baldwin and Reed by the end of the month.
“Actor and producer Alec Baldwin and armourer Hannah Gutierrez-Reed will each be charged with two counts of involuntary manslaughter,” the statement read. “After a thorough review of the evidence… I have determined that there is sufficient evidence.”
“On my watch, no one is above the law, and everyone deserves justice,” she said.
The pair could face up to 18 months in jail and a $5000 fine if found guilty.
New Mexico authorities had previously charged producers, including Baldwin, a total of $139,793 over the incident, finding a “plain indifference” towards gun safety on set.
“I don’t know what happened on that set. I don’t know how that bullet arrived in that gun. I don’t know,” Baldwin said in December 2021.
