Is she crazy – or just truly wicked?…

Here’s double killer Nicola Edgington at work. You see her buying a knife and then running from the scene after she virtually decapitated Sally Hodkin in the street. Edgington previously killed her mother for writing her out of her will. She claimed to be mentally ill – but one of Britain’s top psychiatrists said she is faking and was convicted of murder. She was jailed for life and ordered to serve a minimum of 37 years before she can be considered for parole.
