| contents | <p>This study investigates the transfer of soil to shoe soles when a perpetrator disposes of a corpse in a forested area. During such an action soil is transferred to the shoe soles, but it is unknown which point(s) along the transect transfers the most soil to the shoe soles. This information is needed for taking a soil sample at a crime scene to make a comparison between the crime scene and the shoes which are thought to be linked with the crime. Previous research has mainly been focused on case studies while experimental data is lacking. This study will therefore focus on collecting experimental data by simulating the dumping of a corpse at five different locations. The pollen underneath the boots and the pollen along the transect are compared with each other to see where the highest similarity between the boots and the transect could be found. The similarity indicates where the transfer of soil to the shoe soles is highest and thus where a soil sample during investigation of a crime scene should be taken. The point with the highest similarity to the boots varies between the locations. This indicates that the transfer of soil to shoe soles does not happen at a set point along the transect, but depends on different factors, like moisture, ground coverage and compacted soil. The locations Heemskerk, IJsselstein and Bosrand showed the highest similarity with the points which were the muddiest, had the lowest amount of compacted soil or had limited ground coverage. The locations Schaapsallee and Utrechtse Heuvelrug showed the highest similarity with the average of the total transect because the moisture, ground coverage and compacted soil were comparable throughout the complete transect. In addition, the total transect showed a high similarity with the boots at every location. However, when the amounts of moisture, ground coverage and compacted soil varied along a transect, there was always one point along that transect with a higher similarity to the boots than they had with the total transect. In conclusions, the point(s) were soil is transferred to shoes are the muddiest part, the points with limited ground coverage or the least compacted soil. However, if the whole transect shows similarities in these factors, it is best to take multiple samples along the transect from which the average could be used.</p> |
