DETROIT – Former Detroit Mayor Kwame Kilpatrick was convicted Monday of corruption charges, ensuring a return to prison for a man once among the nation's youngest big-city leaders.

Jurors convicted Kilpatrick of a raft of crimes, including racketeering conspiracy, which carries a maximum punishment of 20 years behind bars. He was portrayed during a five-month trial as an unscrupulous politician who took bribes, rigged contracts and lived far beyond his means while in office until fall 2008.

Kilpatrick wore a surprised, puzzled look at times as U.S. District Judge Nancy Edmunds read the jury's verdict: guilty of 24 charges, not guilty on three and no consensus on three more. Kilpatrick declined to speak to reporters as he left the courthouse.
