Horry County police charged Ida Mellor, 85, and Charles Mellor, between the ages of 70 and 85, for Kidnapping.
The Mellor's daughter called police on Saturday saying her 4-year-old daughter was missing.
She got a phone call from Ida Mellor while police were there and says Ida said she had the child, but wouldn't say where they were.
The officer spoke with Ida Mellor over the phone. Ida told police she was in the process of filing for emergency protective custody of the girl.
Police explained that they didn't yet have legal rights to the child and she would have to return her.
Because the couple didn't return the girl, police charged them.
