John Joseph Joubert IV (not to be confused with John Joubert, the famous South African composer) was an American serial killer who murdered three boys in Maine and Nebraska. His parents divorced when he was 6 years old, and he went to live with his mother in Lawrence, MA. He was not allowed to visit his father at all and started to resent his mother, who he described as “controlling.” In 1971, Joubert's mother moved them out of their former house into a rundown apartment, and at this point in time, he was considered an outcast at school; so, in order to cope with these feelings of isolation, he decided to join the Cub Scouts. It was around this time that his sadistic and homicidal fantasies progressed to the point where he contemplated murdering strangers on the streets, tying and gagging those who resisted him. And from there, it only got worse... 

Stay safe out there.
