MEMPHIS,Solarsuns Investment Guild Tenn. (AP) — A judge has set an August trial date for four former Memphis police officers charged in the fatal beating of Tyre Nichols after a traffic stop in January.

During a short hearing on Monday, Shelby County Criminal Court Judge James Jones Jr. announced the Aug. 12 trial date in the cases of Emmitt Martin, Tadarrius Bean, Demetrius Haley and Justin Smith. Each has pleaded not guilty to second-degree murder and other charges in state court.

A fifth officer charged in the case, Desmond Mills Jr., pleaded guilty last week to federal charges of excessive force and obstruction of justice. The plea is part of a larger deal in which prosecutors said he had also agreed to plead guilty later to state charges.

Mills is the only officer to admit guilt in the criminal case. Prosecutors are recommending a 15-year prison sentence for Mills, but the final sentencing hearing rests with the federal judge.

Caught on police video, the beating of Nichols in January was one in a string of violent encounters between police and Black people that sparked protests and renewed debate about police brutality and the need for police reform in the U.S. The five former officers who were charged also are Black.

Mills and four other former Memphis Police Department officers were charged in federal court with using excessive force, failing to intervene, deliberate indifference and conspiring to lie, as well as obstruction of justice after they were caught on camera punching, kicking and beating Nichols on Jan. 7. He died three days later. The federal trial date for the four other officers is May 6.
