What is bloodstain evidence analysis?

Bloodstain Analysis is the application of mathematics and the laws of physics to bloodstains. It is not mystical interpretation of anything.

References to bloodstains and their importance can be cited all the way back to the Book of Kane and Abel: “The blood cried from the ground…” Many references are made else where in literature throughout history.

Bloodstain Analysis can be used in the Criminal Justice System in several ways. Because blood at the scene of a crime does not work for the prosecution or the defense, the blood can tell the real truth of what may have taken place.

Many times there are conflicting reports made to law enforcement that just don’t make sense. A suspect may say the he or she was fleeing from a scene and that his or her act was in self-defense. If this statement is true and there was bloodshed, the bloodstain evidence may show that the suspect was indeed fleeing from the scene or just the opposite, that the suspect was not fleeing the scene when he or she administered the assault.

Bloodstain Analysis can be used to help sequence the events of a crime. Sometimes with so much disarray at a crime scene, determining what happened can turn out to be a real chore. Bloodstain Analysis can often help unravel this mystery.

Bloodstain Analysis can help law enforcement determine what type of activity took place during a crime. If there is blood evidence left at a scene but no body, the blood can often tell the interpreter if it was a shooting, beating, or a bleeding person simply walking through a house for example.

Bloodstain Analysis can assist forensic pathologists in determining weapons used in an assault because bruising is simply bloodstains on the body.

District Attorneys can use Bloodstain Analysis to help file charges in a homicide where there is no body if it can be proven scientifically that more than 40% of an individual’s blood is found outside his or her body.

Bloodstain Analysis can be used to reconstruct crime scenes and show the movement through a room.

Bloodstain Analysis has many uses in the Criminal Justice System today.

The book “The Evidence Never Lies,” is a book written about Dr. Herbert Leon MacDonell about his work with bloodstains. We encourage everyone to read this book! Contact Dr. MacDonell to see where to purchase a copy.
