Jengo Hooper(2013)

A man named Jake Weaver stumbles across an old Jailakung board which he played around with not knowing it would open up the gates of hell. A demonic force latches onto him and takes over his mind slowly, making the good part of him rot away. Almost like a possession by a demon. Only this demon called itself Jengo Hooper. He starts to suffer from terrible nightmares of evil and macabre activities and slowly drives himself over the edge and turns into a real life psycho cannibal killer. He would butcher victims and perform weird acts of joy upon the dead and if that was not enough he would film and take polaroid photographs of all his activities. After some time he decides he can not going on and tries to commit suicide and its from this point he gets sectioned in Broadmoor Mental prison under the mental health act although the Doctors and medical staff believe he is just suffering from a severe case of Schitzophrenia.
