The federal trial for three former Memphis police officers—Tadarrius Bean, Demetrius Haley, and Justin Smith—charged with the murder of Tyre Nichols commenced on September 9, 2024. Lt. Larnce Wright, a police trainer, testified that the officers did not adhere to Memphis Police Department (MPD) training policies during the violent arrest that led to Nichols' death. He stated the officers employed excessive force, which was unnecessary for a traffic stop, and emphasized that they should have intervened to prevent the beating. The trial included the presentation of footage showing the assault, which caused Nichols' family to leave the courtroom due to its graphic nature. Wright's testimony highlighted that officers are expected to use appropriate force and that failure to comply with department policies could result in federal prosecution. The case follows previous guilty pleas from two other officers involved, underscoring ongoing concerns about police conduct and accountability.
