John Edward Robinson is a convicted serial killer, con man, embezzler, kidnapper and forger who was found guilty in 2003 of three murders and received the death sentence for two of them. He subsequently admitted responsibility for five additional homicides, and investigators fear that there might be other, undiscovered victims as well. Because he made contact with most of his post-1993 victims via on-line chat rooms, he is sometimes referred to as "the Internet's first serial killer". Many of these chat rooms dealt with the BDSM alternative lifestyle and he often went by the name "Slavemaster".
