Blood Pattern Analysis (BPA)
Blood is commonly shed where violence has been inflicted. When blood has been shed there is a need to assess it appearance and distribution in the context of the case. Blood Pattern Analysis (BPA) is a historical, well-documented, technique that is robust and scientifically based and can provide a wealth of useful information to a case study. The Scientific Working Group SWG suggested international standards for the discipline that are accepted by the international association of blood pattern analysts (IABPA). PFS Blood Pattern Analysis experts are members of this international group.
By evaluating and applying objective criteria to blood patterns it may be possible to identify features that can assist in identifying what happened, where, how, what with and by whom. In addition, by studying the blood shed at the scene it may be possible to determine the extent and type of blood patterns expected on the perpetrator.
