The federal investigation of Detroit City Hall corruption that led to the conviction of former Detroit Mayor Kwame Kilpatrick and many others began in 2007. Ultimately Kilpatrick was sentenced on Oct. 10, 2013, to 28 years in prison for turning City Hall into a money-making criminal enterprise.
Kilpatrick was found in guilty earlier this year on 24 counts, including racketeering, extortion, bribery and tax evasion. His friend and co-defendant, contractor Bobby Ferguson, was found guilty of nine crimes.
Kilpatrick's sentencing, one of the harshest corruption sentences in U.S. history, follows the corruption convictions of at least 18 city officials and 16 private individuals.
