The woman named as a suspect in the hit-and-run killing of a Las Vegas nail salon owner is still on the run, although her mother is pleading with Krystal Whipple to surrender. Police say Whipple ran out on a $35 manicure fee and then drove a stolen car over Nhu Nguyen, killing the 51-year-old mother. Nancy Grace looks at the case with a panel including psycho analyst Dr Bethany Marshall, forensics expert Karen Smith, prosecutor Kenya Johnson, and reporter John Lemley. Grace also looks at the disappearance of Nahendra Faye Davis, who vanished two weeks ago after dropping her children off at her mother's Baton Rouge home.
