In Florence, police used Facebook to crack a case involving a 3-year-old girl who was found roaming the street alone. Police put her picture on Facebook, asking if anyone knew her, and somebody did. That led officers to the child’s mother — who had left the girl with a friend for babysiting. That friend now in trouble — 22 year old LeShevia Harris — charged with endangering the welfare of a child. Harris apparently not paying attention. She had no idea the girl wondered off until she heard from police.
