Testimony in the trial of three former Memphis officers charged with fatally beating Tyre Nichols resumes Wednesday, a day after defense attorneys sought to chip away at accusations that the officers used unnecessary force to subdue Nichols after he ran from a traffic stop. Former Memphis officer Desmond Mills Jr. took the stand Tuesday as a prosecution witness against Tadarrius Bean, Demetrius Haley and Justin Smith, who have pleaded not guilty to state charges including second-degree murder in the death of Nichols. Nichols, a 29-year-old Black man, fled a January 2023 traffic stop after he was yanked out of his car, pepper sprayed and hit with a Taser.
