Former Memphis police officer Emmitt Martin has pleaded guilty to federal charges in the death of Tyre Nichols, making him the second officer to do so. Martin admitted to violating Nichols' civil rights and witness tampering, with prosecutors recommending a 40-year sentence. Nichols, a 29-year-old Black man, was fatally beaten by five officers during a traffic stop in January 2023, an incident that was captured on video and led to national outrage and calls for police reform. Martin's plea agreement includes cooperating with the investigation, potentially testifying against the remaining officers who still face trial. Nichols' mother, RowVaughn Wells, described the proceedings as 'bittersweet' and emphasized her desire for full justice for all involved officers.
