The Hinterkaifeck case presents a behavioral profile that sits in contradiction with itself. On one axis: the killer demonstrated weeks of patient, controlled pre-operational surveillance, living undetected in close proximity to the victims, apparently waiting for a specific trigger. On another axis: after the murders, they remained on the farm for four days in a community where their presence could have been discovered at any moment. Behavioral analysts who have studied the case identify this post-crime return-to-scene behavior as consistent with a specific psychological phenomenon sometimes observed in killers who have a deep personal or proprietary relationship with the location itself. What is the formal behavioral term for this pattern of returning to or remaining at a crime scene?
