Modus Operandi[]

"I upped the volts on the charger. I think that helped."

Along with Lee, Colby targeted Caucasian blondes in their 20s. He and Lee abducted their victims by luring them in with the ruse that one or the other was in serious need of aid before pushing her in a van and knocking her out with a blow to the head. After his victims were electrocuted and sodomized like his father's original victims, he stabbed them reluctantly alongside Lee. Colby also made the victim read from a script to reenact his father's last murders. Prior to the abductions, Colby would stalk the victims, take pictures of them, and learn their daily schedules so he could select the best options for Lee.
