Legal representatives of Michael Brown’s parents said they have planned to file a civil lawsuit against the city of Ferguson. Michael Brown was the unarmed black 18-year-old guy who was fatally shot by a white police officer in a St. Louis suburb.

In a statement on Wednesday, lawyers for the parents of Michael Brown said the illegal death court case would be filed the next day. Officer Darren Wilson shot Brown in August. The black guy’s shooting death led to a number of protests, which were renewed in November. The sometime-violent protests were renewed after a jury declined to charge the officer Wilson.

The lawsuit by lawyers for the parents of Michael Brown was expected as in last month, in a press conference Michael Brown’s father, Michael Brown Sr., and mother, Lesley McSpadden, said that they would file a wrongful death lawsuit very soon.

According to the attorneys, Wilson would also be named in the suit. The statement on Wednesday has not mentioned the former officer. While talking to the Associated Press, a spokesman said that he could not provide any additional information about the suit.

The Justice Department did not find sufficient proofs to file federal civil rights charges against the officer. Wilson resigned from the police department shortly after the grand jury decision. A separate Justice Department investigation discovered widespread practices of racial bias. The investigation showed a scathing report representing the city for racial bias.

After the investigation, a number of city officials resigned. The officials who offered resignation include the city manager, police chief and municipal judge. In addition, the municipal court clerk was terminated for racist emails.

More than 60% population of Ferguson is African-Americans. At the time of the shooting, just three of Ferguson’s 53 police officers were black.
