Which blood evidence type involves blood drips creating central stains and satellites?

The correct answer is the drip pattern. This type of blood evidence occurs when blood falls or drips from a source, resulting in the formation of a central stain surrounded by smaller splatter or satellite stains. The central stain is often indicative of the point of origin, while the satellite stains can help investigators determine the nature of the impact and the dynamics of the blood transfer during the event.

Blood drips create these distinct patterns because of the physics involved in the blood's movement. When blood drops from a height, it can create a variety of patterns depending on the force of the drop and the surface it lands on, leading to the formation of the central stain and surrounding satellite stains that are characteristic of a drip pattern.

Other types of bloodstains, such as pooled blood, would appear as larger areas of blood without the spattering that creates satellites. Transfer bloodstains result from direct contact between a blood source and a surface, often creating smears rather than distinct patterns. Wipe patterns occur when an object moves through partially dried blood, altering the blood's original pattern.
