A Heart Rending Smack In The Mouth at Fairoaks Mall in Virginia

This happened today July 3 at about 3pm, it made me so sad - this nanny smacked the little boy in the mouth, he had blue glasses. How can you hit someone so small. She looked guilty when I asked for the parents info and she just took the boy and walked away as if she knew I could not track her down. Please help me try to find the parents, this is so sad
