MICROANATOMY

Detailed explanation-1: -The speed of the weapon used in the attack can cause changes in the size of blood spatter. The speed of the attack is classified into high, medium and low velocity attacks. High-velocity spatter (e.g., gunshot wounds) create small-sized droplets.

Detailed explanation-2: -A High velocity spatter is generally caused by a gunshot wound but can be from a wound from another type of weapon if enough force is used. Once the type of velocity is determined it’s important to determine the angle of impact.

Detailed explanation-3: -“High velocity” A bloodstain pattern resulting from an object impacting a blood source at 100 feet per second or greater. A typical example is spatter resulting from a gunshot. “Medium velocity” A bloodstain pattern resulting from an object impacting a blood source at roughly 25 feet per second.

Detailed explanation-4: -High Velocity Impact Spatter-Bloodstains resulting from blood moving > 30 m/s. e.g. gunshot, machinery. Medium Velocity Impact Spatter – Bloodstains resulting from blood moving between 7.5-30 m/s. e.g. baseball bat blows.

Detailed explanation-5: -High-velocity spatters are usually caused by gunshot wounds, although they can be caused by other weapons if the assailant exerts an extreme amount of force.
