The Zodiac Killer Mysteries and Facts

[loo1]

The prevalence of serial killings in the mid-nineteen hundreds is at large that many of the cases remain a mystery for investigators up to date. For one to be qualified or considered as a serial killer, he or she must have committed three or more murder cases in a period of thirty days with cooling off in between, and that the act must have been driven by a psychological gratification. Thus, every serial killer was and indeed proven a crazed person. And you would also notice that most serial killings by one person happen in a span of more than a year until they are captured and put behind bars. But lucky are the serial killers who are still out there, living no clues of who they are as they continue to prey on their next victim, such as the Zodiac Killer who until now, had not been identified.
