Another study about murder and body disposal:
"The theory proposed in this study was that offenders will operate within their awareness space. In most cases, it appears that the chosen crime site is not random, rather a selected place within the offender’s knowledge space (Brantingham & Brantingham, 1993:5). When examining the disposal sites, all of the offender’s were familiar with the area. In 47 percent of the child, 25 percent of the young adult and 50 percent of the adult cases, the offender knew the area because he lived nearby. Other offenders knew the disposal sites because they had camped in the area, worked nearby, travelled through the area, and a couple of offenders had committed previous crimes in the area. In this study 62 percent of offenders planned ahead of time where they would dispose of their victims."
