The Son of Sam could have been an early experiment? Berkowitz claimed his neighbors dog told him who to kill and the voice of god tech has been around since the 70s.
>After his admission to Sullivan prison, Berkowitz began to claim that he had joined a Satanic cult in the spring of 1975.[citation needed] In 1993, Berkowitz made these claims known when he announced to the press that he had only killed three of the Son of Sam victims: Donna Lauria, Alexander Esau and Valentina Suriani.[105] In his revised version of the events, Berkowitz said that other shooters were involved and that he fired the gun only in the first attack (Lauria and Valenti)[106] and the sixth (Esau and Suriani).[107] He said that he and several other cult members were involved in every incident by planning the events, providing early surveillance of the victims, and acting as lookouts and drivers at the crime scenes.[106] Berkowitz stated that he could not divulge the names of most of his accomplices without putting his family directly at risk.[26]
