The police are reviewing surveillance video to find a woman who gave birth in a restroom stall in Greenville and then left the baby in the toilet. The infant boy is in stable condition, after being discovered Friday by custodians at an arena where a circus had taken place. Dozens of people have volunteered to adopt the 6-pound baby, the police said. The baby is believed to have spent at least an hour in the toilet before custodians heard him crying.
