In Tennessee, a former Memphis police officer pleaded guilty Thursday to two felony charges in federal court for the beating death of Tyre Nichols, a 29-year-old Black father. Video footage shows five police officers from the elite SCORPION unit brutally beating, tasing and pepper-spraying Nichols, who died three days later. As part of a deal for his guilty plea, Desmond Mills Jr. will cooperate with state prosecutors in their separate cases against the officers, which include second-degree murder charges.
