Several officers are being investigated for the death of Robert Brooks at Marcy Correctional Facility.

According to a filing by the state Attorney General's Office, an autopsy conducted in December showed that Brooks suffered bruises to his face and a fractured nasal bone among other injuries to his neck and other extremities.

While the final cause of death is currently pending, the filing states the medical examiner preliminarily reported the death was due to the actions of another person.

The AG's office recused itself from the case, handing it off to Onondaga County District Attorney William Fitzpatrick due to a conflict of interest regarding four of the officers. The District Attorney of Onondaga County also met with family members of Brooks on Thursday along with attorneys representing the Brooks family.

Spectrum News 1 spent time with Elizabeth Mazur, an attorney with a Chicago law firm who is part of the team representing the Brooks family.

“The Brooks family is just a remarkable family, beyond lovely people,” said Mazur.

She and relatives of Brooks share a difficult experience. They met with the AG’s office two days before Christmas and watched the disturbing video of Brooks being beaten by corrections officers inside the walls of Marcy Correctional Facility.

"That was, a difficult meeting," she said. "I think anybody who sees that video just kind of sees horrific images. It's hard for anyone to watch. But I think it was especially hard for them to know that that was how their loved one died, how he spent his last moments of life. It was just, I think it was very painful for the family to watch and to know that that's how, they lost Robert.”

It happened on Dec. 9 and Brooks died on Dec. 10. A handcuffed Brooks had been beaten by corrections officers as others looked on.

“I feel like this is probably one of the worst things I've ever seen,” said Mazur.

She and the rest of the legal team are preparing to file a complaint for civil rights violations. She says they will file in federal court on behalf of the family.

“First and foremost, the family wants justice for Robert," she said. "They want to see those officers held accountable. But I think there is kind of this bigger question of like how, how did this happen? How are we operating in a system where this is condoned or facilitated or sort of part of routine operations at Marcy? And so, I think definitely that's going to be part of the legal action we take to try to get to the bottom of that.”

Mazur says as the family mourns, they are waiting for next steps in the criminal case, watching as the civil case is prepared and looking at a bigger picture.

“Significant change is warranted. And I think this is, as horrific as Robert's killing is, I think, what has happened and the video and the response to it presents a real, opportunity to, for change,” said Mazur.

She believes it was an appropriate move for New York’s attorney general to recuse herself from the case because four of the corrections officers involved are defendants in other cases and are represented by her office.

She also said, even though the governor is calling for swift action in the way of arrests, that she doesn’t expect that to happen in the next few days because the Onondaga DA has only just gotten this case and needs to be thorough.
