Across
  1. 5. The pointed or elongated stains which radiate away from the central area of a bloodstain.
  2. 6. Small droplets of blood that are distributed around a drop or pool of blood as a result of the blood impacting the target surface.
  3. 9. Blood which has been reduced to a fine spray, as a result of the energy or force applied to it.
  4. 10. Blood directed back towards the source of energy or force that caused the spatter.
  5. 15. That point where force encounters a source of blood.
  6. 16. The trajectory of a blood drop which can be established by its angle of impact and directionality angle.
  7. 17. An absence of strains in an otherwise continuous bloodstain pattern.
  8. 18. The angle between the long axis of a bloodstain and a predetermined line on the plane of the target surface which represents 0 degrees.
  9. 19. That blood which has been dispersed as a result of force applied to a source of blood. Patterns produced are often characteristic of the nature of the forces which created them.
  10. 22. A small blood drop that originates from a parent drop of blood due to the wave-like action of the liquid in conjunction with striking a surface.
  11. 23. A bloodstain pattern created when blood is released or thrown from a blood-bearing object in motion.
  12. 25. The transfer of blood from a moving source onto an unstained surface. Direction of travel may be determined by the feathered edge.
  13. 26. Blood that is blown out of the nose, mouth, or a wound as a result of air pressure and/or air flow which is the propelling force.
  14. 27. A bloodstain that consists of only its outer periphery, the central area having been removed by wiping or flaking after liquid blood has partially or completely dried.
  15. 31. The acute angle formed between the direction of a blood drop and the plane of the surface it strikes.
  16. 33. A bloodstain pattern that is produced by blood released under pressure as opposed to an impact, such as arterial spurting.
  17. 35. Bloodstain pattern created when blood receives a blow or force resulting in the random dispersion of smaller drips of blood.
  18. 36. Bloodstain drop(s) created or formed by the force of gravity acting along.
  19. 37. Bloodstain pattern(s) resulting from blood exiting the body under pressure from a breached artery.
Down
  1. 1. Blood which travels in the same direction as the source of energy or force which caused the spatter.
  2. 2. Pattern A bloodstain pattern created when an object moves through an existing stain, removing and/or altering its appearance.
  3. 3. The path of the blood drop, as it moves through space, from the impact site to the target.
  4. 4. A bloodstain pattern caused by a medium velocity impact/force to a blood source. A beating typically causes this type of spatter.
  5. 7. A bloodstain pattern created when a wet, bloody surface comes in contact with a second surface. A recognizable image of all or portion of the original surface may be observed in the pattern.
  6. 8. The directionality of a bloodstain or pattern which indicates the direction the blood was traveling when it impacted the target surface. Directionality of a blood drop's flight can usually be established from the geometric shape of its bloodstain.
  7. 11. Rings in blood that result when blood containing air bubbles dries and retains the bubble's circular configuration as a dried outline.
  8. 12. Evidence that liquid blood has come into contact with a surface.
  9. 13. The common point (area), on a two dimensional surface, over which the directionality of several blood drops can be retraced.
  10. 14. Blood in the barrel of a firearm that has been drawn backward into the muzzle.
  11. 20. A bloodstain pattern that is caused by a low velocity impact/force to a blood source.
  12. 21. A bloodstain pattern caused by a high velocity impact /force to a blood source such as that produced by gunshot or high speed machinery.
  13. 24. A bloodstain pattern which results from blood dripping into blood.
  14. 28. The common point (area) in a three dimensional space to which the trajectories of several blood drops can be retraced.
  15. 29. A drop of blood from which a wave, cast-off, or satellite spatter.
  16. 30. The deflection of blood after impact with a target surface that results in straining of a second target surface.
  17. 32. A change in the shape and direction of a bloodstain due to the influence of gravity or movement of the object.
  18. 34. A surface upon which blood has been deposited.
