What type of trauma can lead to medium velocity impact spatter?

Medium velocity impact spatter is typically associated with trauma that generates a moderate level of force, such as blunt trauma and stabbing. In these cases, the application of force can cause blood to be expelled in small droplets that travel a greater distance than those created by low velocity impacts but are not as far-reaching as those produced by high velocity impacts, such as gunshots.

Blunt trauma includes situations where an object strikes a person, leading to injuries that can produce blood spatter through the rupture of blood vessels. Similarly, stabbing can create significant tissue disruption, causing blood to spray when the weapon penetrates and moves through the body. Both types of trauma involve sufficient force to create the characteristic patterns of medium velocity spatter, making them key contributors to this type of evidence at a crime scene.

Gunshot wounds are typically classified under high velocity impact spatter due to the high force and speed of the bullet. Other forms of trauma may generate varying types of spatter, but it is the specific dynamics of blunt and stabbing trauma that primarily produce medium velocity impact spatter.
