Harriett Hornsby Thomas, 27, of the 2400 block of Norton Drive, was charged Saturday with first-degree cruelty to children and abandonment of child.
She was released Sunday from the Columbia County Detention Center on a $27,000 bond, according to a jailer.
On Saturday, a woman driving in the McDonalds parking lot at 4264 Washington Road saw an infant lying in a carrier in a parking space, according to the report. The 56-year-old took the baby inside the restaurant, but no one there claimed the infant.
Columbia County deputies were called to the restaurant about 6:30 p.m.
After police had arrived, Thomas husband, Christopher, came to the restaurant. He said that his wife told him she lost their child and remembered she had gone to McDonalds.
Before walking inside McDonalds, a man said, he saw a woman set down the carrier while dealing with another child. Another woman said that she spoke with Mrs. Thomas, who had the baby with her at that time, as their children played on the playground.
The infant was given to her grandfather by Richmond Countys Division of Family and Children Services, according to the report.
