The Headless stream Killer

Over the past twelve months sixteen individuals went missing. these individuals would be found floating down local streams in Japan. Thier heads completely missing presumably crushed. What's even worse Is that the killers victims are found to be completely random people. That alone continuously baffles Japanese investigators. What is known is that whoever the killer is, he or she is a highly disturbed individual who's prone to psychotic outburst in fits of rage. He or she is probably aslo a reticent person with difficulties socializing. For months the investigators hadn't had a single clue of who the killer was. That was until a piece of DNA was found on the latest victim.
