All cases of 5 officers charged in Tyre Nichols death to be investigated

Details: All previous cases, closed and pending, will be reviewed, the DA's office said in a statement.

• The five former officers are Tadarrius Bean, Demetrius Haley, Emmitt Martin III, Desmond Mills Jr. and Justin Smith.
• They were each also charged with aggravated assault, aggravated kidnapping, official misconduct and official oppression.

Of note: A 22-year-old Black man is suing the city of Memphis — and the same five officers — claiming they assaulted him three days before Nichols' death in early January.

• The description of the alleged assault is similar to the police beating of Nichols.
• Memphis Police Chief Cerelyn Davis previously said the department is reviewing previous arrests and footage from members of the now-disbanded special unit the officers were a part of.

Background: Nichols, a 29-year-old Black man,​ died days after being beaten during a traffic stop last month.

• Two other officers involved in the traffic stop were relieved of their duties, including Preston Hemphill, who is white and is accused of firing a Taser stun gun during the incident.
• Several more Memphis Police Department officers are being investigated in connection with the incident.
