One of the biggest corruption scandals to hit America's juvenile justice system began unfolding in 2007, when parents in a central Pennsylvania county began to complain that their children had been tossed into for-profit youth centers without a lawyer to represent them. The kickback scheme, known as kids for cash," has resulted in prison terms for two Luzerne County judges and two businessmen. Convictions of thousands of juveniles have been tossed out. Now the case is entering its final chapter: a few remaining class action lawsuits. One of those claims drew to a close ... when a federal judge signed off on a settlement in which one of the businessmen, Robert Powell, would pay $4.75 million. Powell, who co-owned two private juvenile justice facilities, served an 18-month prison term after admitting to paying hundreds of thousands of dollars in bribes to former ... Judge Mark Ciavarella Jr. and his boss, Judge Michael Conahan. In return, Ciavarella routinely found children guilty and sent them to Powell's facilities. Ciavarella was convicted in 2011 of racketeering and other charges, and sentenced to 28 years in prison. Conahan, a friend of Powell's who oversaw the scam, pleaded guilty to racketeering and was sentenced to more than 17 years behind bars. A fourth conspirator ... pleaded guilty for his part in the plot and was sentenced to a year in prison.
