2. John E. Robinson, Sr.

5. Armin Meiwes
Meiwes is the German who met a man over the internet who agree to let him kill and eat him. Miewes videotaped the entire grisly affair, and was eventually arrested and sentenced to eight years in jail for manslaughter, ostensibly because his victim, Jürgen Brandes, agreed to the killing.
6. John Katehis

9. Christian Grotheer
Meet Germany’s “first internet murderer.” Using online dating sites, Grotheer met over 100 women and murdered two of them. In fact, during his trial, he wanted the court to consider the fact that “except for these two, all the other 98 are still alive,” so he shouldn’t be considered a serial killer.
