Bloodstain and Blood Pattern Analysis

Bloodstain pattern interpretation is a valuable forensic tool in criminal investigations, helping determine the position of a victim and movement of a victim or suspect after the crime. By analyzing the pattern and distribution of blood spatters and bloodstains, a certified forensic Bloodstain Pattern Analyst like Kerry Graves can help reconstruct the physical events in a crime scene.

Bloodstain and blood spatter pattern analysis can reveal:
  • the series of events during a violent crime,

  • the movements of victim and suspect during and after the crime,

  • the number of wounds the victim likely suffered,

  • the type of weapon used to inflict the injury or death, and

  • other valuable details.

It’s probably not a topic most people like to think too much about, but bloodstain pattern analysis can be a crucial component of criminal investigations. Because blood behaves according to biological, chemical, and physics principles, analyzing the location, patterns, and shapes of blood found at crime scenes. Studying the blood found at a scene can result in powerful evidence that can help prove a defendant’s guilt or innocence.

Would you believe trained professionals can tell the difference between drops of blood left by a person with a bloody nose and those left by a bloody cough? They can also easily distinguish between blood that came from a stab wound and that from a gunshot wound.

While there is an art to bloodstain pattern analysis, it is a science that involves mathematical and scientific equations. An experienced, observant analyst can determine:

  • What weapon caused the injury or death

  • How the victim and the attacker were positioned relative to one another

  • How many people were present at the time

  • What type of injury was caused

  • What happened after the injury or death
