Jack the Ripper
London’s Jack the Ripper was never properly identified, but he is world famous. Not only did he kill prostitutes in the late 1800s, but he removed their sex organs as well. Not much is known about him, but it is clear that he had a severe hatred of women, particularly prostitutes, which has led some people to theorise that his mother might have been one as well. He left his victims on full display on the street for police and citizens to discover.
The Zodiac Killer
Like Jack the Ripper, no one knows who The Zodiac Killer really is. Unlike Jack, the Zodiac did not seclude himself to the shadows, however. One reason that his murders were so sensational was that he would frequently reach out to various media outlets, teasing them with codes and riddles. The killer was active in the ’60s and ’70s, but there has been no trace of him since his final letter to the press in 1974. Even though psychologists never had the chance to examine him, his crimes showed the lack of empathy of a psychopath.
David Berkowitz, aka “Son of Sam”
In the mid-1970s, New York City-based serial killer David Berkowitz sent the entire city into a panic when he began randomly shooting people – mostly young women with long brunette hair – with a .44-calibre revolver. No one knew when or where the “Son of Sam” would strike next, which is what made him so terrifying. He actually started off as a serial arsonist but was not caught until he went on his killing spree. Berkowitz might have displayed signs of psychosis rather than psychopathy – he has since become a born-again Christian in prison and started acting as a peer mentor for fellow inmates.
