One of the five former Memphis police officers charged federally in the beating death of Trye Nichols will plead guilty at a court hearing on Thursday (Nov. 2), NBC News reports.

Desmond Mills Jr.’s lawyer, Blake Ballin, confirmed to NBC News before the hearing that Mills would change his not-guilty plea in September, but Ballin did not discuss details of Mills’ plea agreement.

It’s a stunning about-face in a case that shocked the nation when video surfaced showing the five Black officers viciously beating Nichols, who is also Black, after a Jan. 7 traffic stop. Nichols, 29, died three days later in a hospital.

In February, the five officers pleaded not guilty in a parallel state prosecution. It’s unclear if Mills will also change his plea in that case.

The U.S. Justice Department announced a four-count indictment against the ex-cops on Sept. 12. Federal prosecutors charged them with deprivation of rights under the color of law through excessive force and failure to intervene, and through deliberate indifference; conspiracy to witness tampering; and obstruction of justice through witness tampering.

Mills and the other ex-officers – Tadarrius Bean, Demetrius Haley, Emmitt Martin and Justin Smith – pleaded not guilty to the federal charges.

They were part of a now-disbanded street crimes unit that stopped Nichols for alleged reckless driving.

Memphis Police Chief Cerelyn “CJ’ Davis said an investigation found no evidence of the reckless driving allegation. An autopsy report showed Nichols died from blows to the head and the manner of death was homicide.

State prosecutors charged the five former officers with second-degree murder, aggravated assault, aggravated kidnapping, official misconduct and official oppression.
