Racist emails released Friday by the city of Ferguson reveal that most were sent by a former city court clerk to two police officers and there is no indication other city officials were involved.

The emails were discovered during the investigation into the Aug. 9 shooting death of 18-year-old Michael Brown, who was black and unarmed, by Darren Wilson, a white police officer.

Most of the emails were sent from Court Clerk Mary Ann Twitty to police Capt. Rick Henke and Sgt. William Mudd.

Twitty was eventually fired over the emails, while Henke and Mudd resigned. The Associated Press reports multiple names are redacted and that non-city employees are not named.

Wilson was not indicted by a grand jury in November and was also cleared of civil rights violations by the Justice Department in March.

A separate Justice Department report found widespread racial bias in Ferguson’s policing efforts and the municipal court system, which it said was driven by profit mostly extracted from black low-income residents.

The report cited a series of inappropriate messages sent by an unspecified number of city employees, including one message that compared black welfare recipients to mixed-breed dogs. Several of the emails focused on President Obama, including one that stated he wouldn't be in office for long because "what black man holds a steady job for four years."
