This training is for anyone who will be investigating a death scene, including police officers, death scene investigators, and crime scene technicians.
Blood found at crimes scenes or on victims, suspects, or witnesses (clothing or person) should be considered significant evidence and should be treated as such when being documented, collected
and preserved. Before blood evidence can be properly analyzed, it needs to be properly documented.
At a death scene involving bloodshed it is obviously important to document where the blood is located, but it is equally important to document where the blood is not located. The absence of blood in certain areas of the scene may be as important to the reconstruction of events as the presence of bloodstains. To that end, the scene must be properly documented through photographs, notes, and diagrams in such a way as to leave no doubt as to the locations where blood is located and not located. Tips and techniques for documenting bloodstains in this manner will be explained and re-enforced with actual case samples.
Various blood letting injuries that result in bloodstains at the scene will be discussed. Examples of identifying and documenting injuries will be presented and illustrated through case examples.

• Probative value and limitations of bloodstain evidence
• Identifying sharp force injuries
• Bullet entrance and exit wounds
• Photographing bloodstains from overall, medium, and close up perspectives
• Documentation necessary in determining an active scene from a passive scene
• Using bloodstains to corroborate or refute other evidence collected in the investigation
• Understanding
how much blood should you “expect to find” at a given assault or homicide scene
• Environmental factors that contribute to the drying time of liquid blood
• Common mistakes to avoid when photo-documenting bloodstain evidence
• Suggestions for documenting and collecting blood swabs at the scene
• Proper drying and packaging methods for collecting bloodstain evidence

This program contains graphic scene photographs and actual case examples to illustrate the training material.
