The accidental shooting on the New Mexico film set of "Rust" spawned a yearlong criminal investigation, multiple lawsuits and heartfelt remembrances of cinematographer Halyna Hutchins, who was tragically killed when a prop gun fired.
Multiple people, including star Alec Baldwin, were charged in connection with the deadly shooting. Two have since been convicted, while Baldwin's case was dismissed with prejudice in a shocking turn of events three days into the trial.
Here's a look at key events in the incident, which sent shockwaves throughout the entertainment industry.
The New Mexico Film Office announced that "Rust" was currently in production in Santa Fe, with filming scheduled to go until early November 2021.
While on the set of the Western at Bonanza Creek Ranch, Hutchins, 42, was shot and killed by Baldwin while he was practicing using a Colt .45 revolver. Director Joel Souza was also injured in the shooting.
First assistant director David Halls had handed the gun to Baldwin while proclaiming "cold gun," to let the crew know a gun with no live rounds was being used, according to a search warrant affidavit. However, Hutchins was killed by a live round inside the gun, authorities said.
The Santa Fe County Sheriff's Office said it is investigating the incident.
The film's script supervisor, Mamie Mitchell, announced she has filed a civil suit accusing Baldwin of "playing Russian roulette" by pointing a Colt .45 revolver at Hutchins.
In his first interview following the shooting, Baldwin told ABC News' George Stephanopoulos that he had "no idea" how a live bullet got onto the set of his film, but that he "didn't pull the trigger" on the firearm. He also said he didn't believe he would face criminal charges for the tragedy.

The family of Hutchins filed a wrongful death lawsuit, alleging reckless behavior and cost-cutting by Baldwin and others led to Hutchins' death.
The New Mexico Environment Department's Occupational Health and Safety Bureau issued Rust Movie Productions a "willful" citation, including a $136,793 penalty, for failures that led to Hutchins' "avoidable death." This is the highest level of citation and maximum fine allowable by state law in New Mexico.
The family of Hutchins announced they had reached a settlement in their wrongful death lawsuit against the film's producers.
As part of the settlement, Matthew Hutchins, Halyna's husband, took over as executive producer of the film and it was announced the principal actors and director would restart filming in January 2023.
Santa Fe County sheriff investigators confirmed they had turned over their report to Santa Fe First Judicial District Attorney Mary Carmack-Altwies, who will decide whether to press criminal charges against anyone involved in the shooting.
Baldwin filed a lawsuit over the fatal shooting, alleging negligence of several of the film's crew members. The cross-complaint, which named the Western's first assistant director, armorer, ammunitions supplier and prop master as defendants, follows the lawsuit filed last year by the film's script supervisor.
The Santa Fe County Sheriff's Office released its 550-page report into the fatal shooting.

Halls already agreed to plead no contest to the charge of negligent use of a deadly weapon.
No charges will be filed in the shooting of Souza, the district attorney's office said.
Carmack-Altwies formally filed involuntary manslaughter charges in the shooting.
The filings claimed that Baldwin and Gutierrez failed to correct reckless safety violations in their roles as producer and armorer, respectively, and that Baldwin had his finger inside the trigger and the trigger was pulled -- contradicting his statements saying he never pulled the trigger.
Halls' plea agreement is pending a judge's approval, prosecutors said.
Baldwin's attorney filed a motion seeking to disqualify Andrea Reeb, the special prosecutor who investigated the fatal shooting, due to her role as a member of the New Mexico House of Representatives. The attorney, Luke Nikas, claimed that Reeb violated a separation-of-powers provision in the New Mexico Constitution and argued that she cannot simultaneously exercise legislative and judicial power.
In a statement in response to the motion, a spokesperson for the district attorney's office called it a tactic to "distract from the fact that Halyna Hutchins died because of gross negligence and a reckless disregard for safety on the 'Rust' film set."
Hutchins' parents and sister, who live in her native Ukraine, file a lawsuit in Los Angeles County Superior Court against Baldwin, the film's producers and several crew members, alleging battery, intentional infliction of emotional distress, negligence and loss of consortium.
Baldwin's legal team filed a motion arguing that the five-year gun enhancement didn’t apply at the time of the shooting writing, "The prosecutors committed a basic legal error by charging Mr. Baldwin under a version of the firearm-enhancement statute that did not exist on the date of the accident."
The accident occurred in October 2021, but the current version of the law did not take effect until May 2022.
The district attorney's office again said it was a tactic to distract from responsibility for the shooting and "the DA's and the special prosecutor's focus will always remain on ensuring that justice is served and that everyone -- even celebrities with fancy attorneys -- is held accountable under the law."
The Santa Fe District Attorney's Office announced it is dropping the gun enhancement charge -- a crime that would have carried a five-year sentence if convicted -- against both Baldwin and Gutierrez.
Baldwin and Gutierrez still face charges of involuntary manslaughter for the shooting, however, that crime would carry a lesser sentence of 18 months if convicted. The amended complaint was filed on Feb. 17, 2023.
"In order to avoid further litigious distractions by Mr. Baldwin and his attorneys, the District Attorney and the special prosecutor have removed the firearm enhancement to the involuntary manslaughter charges in the death of Halyna Hutchins on the 'Rust' film set," Santa Fe District Attorney Mary Carmack-Altwies said in a statement. "The prosecution's priority is securing justice, not securing billable hours for big-city attorneys."
Baldwin entered a plea of not guilty and waived his first court appearance in a court document filed a day before he was scheduled to appear virtually in court. A district judge also issued an order setting conditions of Baldwin's release, including that he must not possess any firearms, not consume alcohol and have no contact with any potential witnesses unless it's related to filming the movie.
Halls also filed a waiver of first appearance on Feb. 22, 2023, and pleaded not guilty, court records show.

Rust Movie Productions has agreed to pay $100,000 -- down from the original $136,793 civil penalty issued by the agency -- and the citation was amended from "willful-serious" to "serious," according to the agreement.
Reeb announced she will step down from the case, saying in a statement issued by the Santa Fe district attorney's office that she will "not allow questions about my serving as a legislator and prosecutor to cloud the real issue at hand."
The district attorney's office announced that Carmack-Altwies will step away from prosecuting the case and has appointed New Mexico attorneys Kari Morrissey and Jason Lewis to serve as special prosecutors.
Halls was sentenced to six months unsupervised probation as part of a plea deal.
Charges against Baldwin in the shooting have been dropped, according to sources familiar with the matter.
The development came as "Rust" resumed production at Yellowstone Film Ranch in Montana with the original producers and principal cast, including Baldwin.
Prosecutors additionally charged Gutierrez with tampering with evidence for allegedly transferring narcotics to another person following her interview with police in the wake of the shooting.

The special prosecutors said they believe Baldwin has "criminal culpability" in the deadly shooting and announced that they intend to present the case to a grand jury to "determine whether probable cause exists to bind Baldwin over on criminal charges."
A grand injury indicted Baldwin on involuntary manslaughter in the shooting.
Baldwin entered a plea of not guilty in a court filing waiving his arraignment on involuntary manslaughter.
A jury found Gutierrez guilty of involuntary manslaughter after deliberating for less than three hours in her trial. She was found not guilty of tampering with evidence.
Judge Mary Marlowe Sommer sentenced Gutierrez to the maximum of 18 months in prison.
"You alone turned a safe weapon into a lethal weapon," the judge said. "But for you, Ms. Hutchins would be alive. A husband would have his partner, and a little boy would have his mother."
Hutchins' parents and sister, along with Mitchell, file a lawsuit in the First Judicial District of New Mexico for Santa Fe County against Baldwin, the film's producers and several crew members, after the dismissal of their cases in Los Angeles County. The complaint alleges battery, intentional infliction of emotional distress and negligence.
Jury selection began in Baldwin's involuntary manslaughter trial. Sixteen jurors -- including four alternates -- were selected by the afternoon. The jury was made up of 11 women and five men.
Marlowe Sommer said the trial was expected to last two weeks.
Three days into Baldwin's manslaughter trial, Marlowe Sommer issued a stunning decision when she grants the defense's motion to dismiss the case.
Baldwin's attorneys claimed live ammunition that came into the hands of local law enforcement related to the investigation into the deadly on-set shooting was "concealed" from them.
Marlowe Sommer said the state's discovery violation regarding the late disclosure of a supplemental report on the ammunition evidence "injected needless delay into the proceedings," approached "bad faith" and was "highly prejudicial to the defendant."
The judge granted the motion to dismiss with prejudice, meaning Baldwin cannot be tried again on the charge.
