The federal probe of public corruption in metro Detroit has resulted in the conviction of nine people and the indictment of two others. Ex-Detroit Mayor Kwame Kilpatrick, his father, Bernard Kilpatrick, and former Kilpatrick administration officials Derrick Miller and DeDan Milton have also been under federal scrutiny, according to Free Press sources and the newspaper’s analysis of federal records. Here is a breakdown of the investigations:

SYNAGRO SLUDGE DISPOSAL CONTRACT

Monica Conyers: The former president pro-tem of Detroit’s City Council pleaded guilty to bribery for taking at least $6,000 to vote in favor of giving Synagro a $1.2-billion deal to dispose of the city’s sludge. She is to be sentenced Jan. 15 and faces up to 5 years in prison.

Rayford Jackson: The Detroit developer pleaded guilty to a bribery charge and was sentenced last month to 5 years in prison. He admitted giving Conyers at least $6,000.

James Rosendall: The Grand Rapids businessman and Synagro executive pleaded guilty to bribery. He admitted supplying cash, campaign contributions, chartered flights and luxurious gifts to gain the support of Detroit officials. Because he cooperated with the federal probe, he received a more lenient sentence of 11 months in prison. He was also ordered to pay a $200,000 fine.

Sam Riddle: The political consultant and Conyers aide was indicted on bribery charges. He is to go to trial in January and in February in a second bribery case in Southfield.
