CONWAY, S.C. -- A woman has been charged with kidnapping a 2-week-old South Carolina infant found unharmed in a plastic bag.

Multiple media outlets reported that 30-year-old Annette Melissa Rich of Myrtle Beach was arrested Wednesday.

Conway police say Sharawn Jerod Chestnut Jr. was found Tuesday afternoon and returned to his mother after a news conference about his disappearance.

The boy's mother told police she put her infant son to bed around 11 p.m. Monday and he was missing when she checked an hour later.

Police say Rich took the baby late that night. A family spokeswoman says the baby was found in a plastic bag under the seat of a vehicle in a restaurant parking lot.

Rich was in the Horry County jail on $75,000 bond. It was not clear if she had an attorney.
