The family of a 29-year-old man who was killed as a result of a police beating during a traffic stop in January filed a civil lawsuit Wednesday against the City of Memphis, its police department, and the officers involved.

In January, five officers performed a traffic stop on Tyre Nichols and brutally beat him after he attempted to run away. Nichols died in the hospital three days later. The case is in the US District Court for the Western District of Tennessee Western Division.

The 139-page complaint asserts that the now-disbanded Memphis police team known as the Street Crimes Operation to Restore Peace In Our Neighborhoods (SCORPION) Unit “brought terror” and was an “officially authorized gang of inexperienced, untrained, and hyper-aggressive police officers.” The officers involved in the traffic stop were part of this unit. Additionally, the complaint alleges that the City of Memphis was indifferent to SCORPION’s “unsupervised reign of terror.” Lastly, the complaint asserts that the officers stopped Nichols “without legal justification” and beat Nichols “within an inch of his life.”

The complaint sets forth 25 causes of action, which include Failure to Train, Failure to Supervise, Fourth Amendment violations, Negligent Infliction of Emotional Distress and Fraudulent Misrepresentation.

In response to the complaint, the estate’s attorney Ben Crump stated:

How does this horrific and unconstitutional treatment of Black men and women by law enforcement continue to happen. Tyre’s condition in the hospital can be likened to that of Emmitt Till who was also beaten unrecognizable by a lynch mob. But, Tyre’s lynch mob was dressed in department sweatshirts and vests, sanctioned by the entities that supplied them. Please, Memphis. Please, America, we must hold these people accountable and create meaningful change once and for all. We can not let another seventy years go by.

The lawsuit also names two Memphis Fire Department emergency medical technicians for allegedly failing to provide medical care to Nichols when it was “obviously necessary” to do so.

A Tennessee Grand Jury indicted the five officers involved in Nichols’ death in January.
