Across 2. The common point (area), on a two dimensional surface, over which the directionality of several blood drops can be retraced 5. The trajectory of a blood drop which can be established by its angle of impact and directionality angle 9. The deflection of blood after impact with a target surface that results in straining of a second target surface 10. The path of the blood drop, as it moves through space, from the impact site to the target 16. The common point (area) in a three dimensional space to which the trajectories of several blood drops can be retraced 18. An absence of strains in an otherwise continuous bloodstain pattern 22. A bloodstain pattern caused by a high velocity impact /force to a blood source such as that produced by gunshot or high speed machinery 26. Evidence that liquid blood has come into contact with a surface 28. 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 30. That blood which has been dispersed as a result of force applied to a source of blood 32. Bloodstain pattern(s) resulting from blood exiting the body under pressure from a breached artery 33. Small droplets of blood that are distributed around a drop or pool of blood as a result of the blood impacting the target surface 34. Blood in the barrel of a firearm that has been drawn backward into the muzzle 35. Blood which has been reduced to a fine spray, as a result of the energy or force applied to it 36. A bloodstain pattern created when an object moves through an existing stain, removing and/or altering its appearance 37. A drop of blood from which a wave, cast-off, or satellite spatter

Down 1. A bloodstain pattern caused by a medium velocity impact/force to a blood source 3. The directionality of a bloodstain or pattern which indicates the direction the blood was traveling when it impacted the target surface 4. 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 6. The transfer of blood from a moving source onto an unstained surface 7. Bloodstain drop(s) created or formed by the force of gravity acting along 8. A surface upon which blood has been deposited 11. A bloodstain pattern that is produced by blood released under pressure as opposed to an impact, such as arterial spurting 12. A bloodstain pattern which results from blood dripping into blood 13. Blood which travels in the same direction as the source of energy or force which caused the spatter 14. That point where force encounters a source of blood 15. A bloodstain pattern that is caused by a low velocity impact/force to a blood source 17. The angle between the long axis of a bloodstain and a predetermined line on the plane of the target surface which represents 0 degrees 19. 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 20. A change in the shape and direction of a bloodstain due to the influence of gravity or movement of the object 21. Bloodstain pattern created when blood receives a blow or force resulting in the random dispersion of smaller drips of blood 23. The acute angle formed between the direction of a blood drop and the plane of the surface it strikes 24. A bloodstain pattern created when a wet, bloody surface comes in contact with a second surface 25. Blood directed back towards the source of energy or force that caused the spatter 27. A bloodstain pattern created when blood is released or thrown from a blood-bearing object in motion 29. Rings in blood that result when blood containing air bubbles dries and retains the bubble's circular configuration as a dried outline 31. The pointed or elongated stains which radiate away from the central area of a bloodstain
