A registered sex offender who approached a teenage girl in the library Monday is behind bars, Statesboro Public Safety Director Wendell Turner said. Bobby Joe Rivers, 49, of West Main Street, walked up to a 14-year-old girl in the Statesboro Regional Library around 11:46 a.m. Monday and made inappropriate comments, Turner said. Advanced Patrol Officer Nathan Bolton met with the teen and her parents, who told him Rivers asked her to come to his house to draw for him, Turner said.
