Bus hijacking by a pre-schizophrenic: from a viewpoint of criminal romance

There are cases in which no clear symptoms of schizophrenia are observed in a person at the time of a crime but are diagnosed to have schizophrenia after the crime due to the appearance of typical symptoms. We present psychiatric evidence of a patient who saw a bus hijacking incident on TV during several years of isolation at home after graduation from junior high school, and was then determined to hijack a bus, and carried out the crime 6 months later. The patient exhibited clear symptoms of schizophrenia 3 days after the crime. This case of a crime committed before the appearance of clear symptoms of schizophrenia was evaluated from the viewpoint of verbrecherromantik or 'criminal romance'.
