The separated parents of a 3-year-old Maryland girl forgot something when they left a recent party at Chuck E. Cheese … their little girl.

A restaurant manager had called authorities three hours earlier when staff found the girl alone, but deputies were unable to reach her parents. No charges are expected. (More Chuck E. Cheese stories.)
