Introductory Bloodstain Pattern Analysis Workshop

Miami-Dade Public Safety Training Institute, 9601 NW 58th St., Doral, FL 33178

December 7-11, 2020

Violent crimes usually result in bloodshed.  When physical forces act upon liquid blood, patterns will be deposited on the various items at the crime scene, as well as the clothing of the individuals present during the activity.  These patterns can yield valuable information concerning the events that lead to their creation.  The information can then be used for reconstruction of the incident, as well as to evaluate the statements of the witnesses and the crime participants.  Bloodstain pattern evidence can be of value in the investigation of any violent crime in which bloodshed occurs. 


Workshop objectives:

1) Teach the investigator how to identify bloodstain pattern evidence at the crime scene.

2) Teach the investigator how to properly document bloodstain pattern evidence.

3) Teach the investigator how to properly preserve the bloodstain pattern evidence.

4) Teach the investigator how to reconstruct bloodstain patterns at the crime scene.

5)Provide the foundation for teaching the investigator how to interpret bloodstain pattern evidence.

6) Teach the investigator the safety and health issues associated with bloodstain pattern evidence.


Workshop Goals:
1) To be able to recognize bloodstain pattern evidence at the crime scene.

2) To be able to properly document and preserve the bloodstain pattern evidence.

3) To be able to properly use bloodstain pattern terminology.

4) To be able to identify simple bloodstain pattern types.

5) To obtain basic bloodstain pattern analysis knowledge that will be the foundation for additional training culminating in being able to evaluate and interpret bloodstain pattern evidence and render an opinion concerning that interpretation.

The objectives and goals will be achieved through lecture, discussion, practical experiments with blood, and case studies.
