[Possibilities and limitations of forensic bloodstain pattern analysis].

Forensic bloodstain pattern analysis includes the detection, shape analysis, classification and interpretation of relevant traces of blood at a crime scene with the aim of reconstructing the sequences of the events that occurred. Mathematical calculation of impact and cast-off patterns are the center of the analytical reconstruction, when predicting the position of the source of blood stain at the moment of impact. Taking into consideration the limits of this method, it is possible to verify reconstructions of criminal acts and reconstruct a possible sequence of events that occurred. The present article is intended to give a brief introduction to various aspects of the forensic bloodstain pattern analysis as well as to point out the application possibilities and limitations of this forensic subdiscipline.
