John Edward Robinson

John Edward Robinson (born December 27, 1943) is an American convicted serial killer, kidnapper, rapist, and forger. He was found guilty and received the death penalty in 2003 for three murders committed in Kansas. Two years later, as part of a plea deal, he admitted responsibility in five other murders committed in Missouri, for which he received multiple life sentences without possibility of parole. Robinson, a prolific con man and embezzler, used online chatrooms to make contact with some of his victims while under the alias "Slavemaster" – this makes him the first known serial killer to have used the internet to lure in victims.
