What kind of bloodstains can be created by a body being dragged?

When a body is dragged, the type of bloodstains created are classified as transfer bloodstains. Transfer bloodstains occur when blood comes into contact with a surface, allowing the blood to be transferred from one object to another. In this scenario, as the body is moved, blood from the body can be transferred onto the surface underneath, creating a pattern that reflects the movement and direction of the dragging action.

These stains can provide valuable forensic information, such as the path the body was dragged and the position of the person at the time of contact. The transfer of blood can also suggest whether the blood was wet or dried, which can give further context to the timeline of events associated with the scene. This distinction is crucial for investigators to understand the dynamics of the crime scene and to reconstruct what transpired.

In contrast, impact bloodstains are formed from blood that is struck or impacted, passive bloodstains result from gravity allowing blood to fall directly to the ground, and projected bloodstains involve blood being expelled through force, such as from a gunshot or a vigorous movement, none of which directly apply to the scenario of a body being dragged.
