Robert K. Ressler, the FBI's head profiler at the time, had access to the information about the two boys in Nebraska and worked up a hypothetical description which matched Joubert in every regard. While presenting the case of the two Nebraska boys to a training class at the FBI academy at Quantico, a police officer from Portland, Maine, noted the similarities to a case in his jurisdiction which took place while Joubert had lived there prior to joining the Air Force. Bite mark comparisons proved that Joubert was responsible for the Maine killing in addition to those in Nebraska. Ressler and the Maine investigators came to believe that Joubert joined the military to get away from Maine after the murder of the Stetson boy.
