Did the article discuss areas of awareness and the likelihood that killers will act and dispose of bodies within those areas? I think I remember it and I know I remember nursebeeme linked a very good article about that subject in the Jessica Ridgeway case (austin Sigg was the perp in that one). Not sure if this is the article but if not it is similar and discusses awareness space.
The Spatial Psychology of Serial Offending
The serial offenders operating location is vitally important to an investigator since that information can lead to the offenders identity and arrest. This location is called an anchor point; it is the place from which the offender leaves to commit a crime, returns to after committing a crime, or both. Most often the anchor point is a residence, but it could also be a workplace or other central location. The offenders anchor point is directly related to the locations of his crime scenes. The pattern describing this relationship can be simply stated as follows:
Offenders commit crimes close to their anchor points.
The frequency of offending decreases as the distance from their anchor point increases.
