In 1971, Joubert's mother moved them out of their former house into a rundown apartment. At this time, he was considered an outcast at school, and sought to compensate for these feelings of isolation by joining 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. In one later psychiatric report, he was described as saying that he derived pleasure from the thought of his victims saying "if you are going to do it, get it over with."
