Types of Blood Stains: Unveiling Forensic Clues
Passive Stains: Result from the force of gravity acting on blood, causing it to drip, flow, or pool. Examples include blood drops, flows, and pools.
Transfer Stains: Occur when wet, blood-bearing surfaces come into contact with another surface, leaving an impression. Common examples include swipe and smear patterns.
Projected Stains: Result from blood being propelled into the air and landing on a surface under some force. Patterns include splashes, spurts, or cast-off stains.
Arterial Spurts: Result from blood exiting the body under pressure from a breached artery, creating distinctive spurting patterns often associated with arterial wounds.
Expirated Blood Patterns: Occur when blood is expelled from the nose, mouth, or respiratory system due to internal injuries, forming distinctive spatter patterns.
Impact Spatter: Results from the forceful impact of an object against a blood source, producing fine droplets that radiate outward from the impact site.
Understanding the characteristics of different blood stain patterns is crucial in forensic investigations, aiding in reconstructing crime scenes, determining the type of injuries inflicted, and providing valuable insights into the dynamics of violent events.
