Willoughby Hills, Ohio, United States. A leafy and normally quiet suburb of Cleveland. That is until the 16th November 2012, when police receive a 911 call at 1:15 am from a young girl asking for help, hysterically telling dispatchers that her mother was being stabbed.   Police arrived at the scene, entered the home, and were pointed in the direction of the master bedroom. They find a horrific scene. The bedroom was awash with fresh blood, and the bedsheets completely transformed into a sea of scarlet red, so much so, it was impossible to tell what colours they had been previously. Disguised beneath all this blood, the dead body of a woman, and standing over the body, a young girl covered in blood, knife in hand, looking very calm, almost peaceful. This is a case that shook all those involved, including the police investigators who had to use all of their experience and patience to get to the bottom of it.
