A Gainesville, Ga., man alerted authorities after he arranged on Craigslist to drive someone to Florida and later learned that someone was a 9-year-old boy. The man had posted an advertisement on Craiglist offering to split the cost of driving a woman’s son to the Sarasota area. Shelia Sherrie Joyner of Marietta responded to the ad saying she wanted to send her son to visit his grandmother, according to Cobb County police spokesman Dana Pierce.
