Video's just now making rounds, but this happened in April 2009.
From the Rome Times-Tribune/April 2009: "An Alabama woman was arrested Tuesday afternoon after police say she injured a child while dragging it through a store in Rome.
According to Floyd County Jail records:
Melissa Catherine Smith-Means, 37, of Gaylesville, Ala., was arrested by Rome police around 12:30 p.m. She was charged with felony first-degree cruelty to children.
Police say she was observed by customers and employees at a store on Broad Street, dragging a small child around by a backpack leash. The child had visible marks on the neck from the incident."
