The cops certainly think so, as he is prosecuted and must undergo a lie detector test in this look at upcoming episodes. While its unclear if Norman has what it takes to claim a human life, we certainly know that his high school crush Bradley Martin is capable of extinguishing souls at will. Watch this montage of exhilarating new footage, and then ask yourself, 'Who is Norman Bates?'
