Convicted Serial Killers – 26
Some serial killers may have possibly existed way back. There is one interesting story from Germany of a man from the 16th century. The story reportedly tells of the killers victims nearing 1000. Though many have discredited it as merely a story, the actual pamphlet itself was said to have been produced based from facts of an actual convict. The story was published before the actual murderer was executed.
