Bloodstain Pattern Analysis (BSPA) is a forensic investigation tool that is based on scientific principles.  It relies on the fact that blood, as a fluid, will follow certain physical laws, and as such, will form reproducible patterns under separate sets of similar circumstances.

   We are concerned with the static aftermath of a bloody event.  The resultant bloodstains are then characterized in terms of their size, shape and distribution patterns.  These features of the bloodstains may then be used to determine the following critically important information:

 

  • The positions of the victim, assailant and objects at the scene.
  • The type of weapon used to generate the bloodstain patterns.
  • The number of blows, shots, stabs, etc. that occurred.
  • The movement of victim and assailant after onset of bloodshed.
  • It may confirm or refute statements made by  witnesses.


   Bloodstain Pattern Analysis may then be able to determine:

 

  • What events occured.
  • When and in what sequence they occurred.
  • Who was, or was not present.
  • What did not or could not occur.

   The following links are excellent resources for those interested in obtaining a better understanding of the various types of identifiable bloodstains and the mechanisms and conditions which generate those bloodstains.
