Estimating the deposition height of passive bloodstains

Estimating the deposition height of passive bloodstains

Bloodstain pattern analysis (BPA) is one of the few forensic disciplines that are able to give a statement about what has happened at a crime scene instead of who was present at a crime scene. In order to make a reconstruction of the crime, the origin of individual bloodstains is important. At the University of Amsterdam, a method was developed to determine the flight path of each individual stain, based on its surface area and the volume [Laan 2014].

The method was validated for so-called impact patterns [Laan2015]. In this project, the method will be extended to passive bloodstains to estimate the fall height of the droplet.
