An aide to Democratic gubernatorial hopeful Sue Bell Cobb turned himself in to face a charge of violating a state sex offender law, authorities said Thursday evening. The Jefferson County Sheriff's Office says Paul Littlejohn, 55, violated the Sex Offender Registration and Notification Act. Investigators say Littlejohn failed to report his employment at Greater Shiloh Missionary Baptist Church. The church runs a daycare and is near a school, two places Littlejohn, a convicted rapist, is prohibiting from living or working near. Earlier Thursday, Cobb voiced support for Littlejohn, her deputy field director in Jefferson County. Littlejohn served 30 years for the 1984 rape and sodomy of a woman. Dismissing the idea that she would fire him, Cobb said Littlejohn "paid his debt to society," and "dedicated his time to rehabilitating himself." Cobb has not commented since Littlejohn's arrest. Bond was set at $11,000.
