An Ohio mom tells cops she killed her 5-year-old daughter because the child became too much to handle after a visit with grandparents. A confession video shows Mingming Chen complaining she didn't have the "4 hands" needed to discipline little Ashley, so she killed her and told her husband to "deal with it." The dad stuffed the child behind a freezer in their restaurant before calling police to report her missing. Nancy Grace digs into this case with journalist Jane Velez-Mitchell, psychologist Dr. Pat Saunders, private investigator Vincent Hill, lawyer & child advocate Ashley Willcott, & Crime Stories co-host Alan Duke. Nancy and guests also look at animal cruelty by dog owners who leave pets out in the cold to die during the arctic blast.
