Passive Stains
Drops, Flows, and Pools, results from gravity acting
Transfer Stains
object coming in contact with existing blood stains and leaving wipes, smears, or pattern transfers
Impact Stains
blood projecting through air and usually seen as splatters. (May also include gushes, splashes, and arterial spurts.)
Gunshot Splatter
Includes forward splatter from exit wound and back splatter from entrance wound. Typically: Forward is a fine mist and the back is larger, fewer drops.
Cast-Off
Results when an object sung in arc flings blood onto nearby surfaces. Tail points in direction of motion and the number of arcs can show minimum number of blows.
Arterial Spray
Spurt of blood when a major artery is severed with new pattern created each time the heart pumps
Expired Splatter
blood from an internal injury mixing with air from lungs being expelled through the nose, mouth, or an injury to airways or lungs, forms a very fine mist and some blood stains are latent.
Sharp Force Injuries (Stabbing)
Less blood being deposited on the instrument, smaller more linear patterns of stains
Blunt Force Injuries (Hitting or Beating)
larger surface area will collect more blood, producing drops of various sizes.
Gunshot Injuries
Mist like splatter caused by bullets entering and exiting a body.

opposite side. There are no deltas in this pattern
*There are two types of these patterns
Loop
