The internet has changed the way the entire world functions in a relatively short amount of time, and it should be no surprise that, for as many benefits as the internet has brought us, there are many dark corners of cyberspace where serial killers search for (and find) their victims. On this installment of 13 O’Clock, Tom and Jenny delve into some true crime cases, and discuss a handful of serial killers who used the internet as a significant means of stalking their prey or bragging about it afterwards. We’ll talk about notorious “Internet Slave Master” John Edward Robinson, also known as The Internet’s First Serial Killer; the British murderer Stephen Port, called the Grindr Killer; Todd Kohlhepp, The Amazon Review Killer; and Hiroshi Maeue, The Suicide Website Murderer. Make sure you reinforce your firewalls and clear your browser histories, because we’re diving deep into the dark side of the web on episode 291.
