Chapter 10 Crossword - Blood Spatter
Across
1. An impact spatter pattern created b y a force traveling at 100fps or faster and producing droplets with diameters
less than 1mm.
3. A chemical reagent that reacts with the iron in hemoglobin to produce a blue color when the test is positive.
4. A bloodstain pattern that is created when blood is flung from a blood-bearing object in motion onto a surface.
5. A pattern of bloodstains formed by the dripping of blood off a moving surface or person in a recognizable pathway
separate from other patterns.
11. Small droplets of blood that are distributed around the perimeter of a drop or pool of blood and were produced as a
result of the blood impacting the target surface.
12. The area on a two-dimensional plane where lines traced through the long axis of several individual bloodstains
meet.
13. The location in three-dimensional space that blood that produced a bloodstain originated from.
14. Blood that travels away from the source in the same direction as the force that caused the spatter.
15. Also known as "blood reagent tests" and are used to chemically test for the properties of hemoglobin.
16. A characteristic bloodstain pattern containing spurts that resulted from blood exiting under pressure from injury
to an artery.
17. A bloodstain pattern produced when an object makes forceful contact with a source of blood, projecting droplets of
blood outward from the source.
18. Blood directed back toward the source of the force that caused the spatter.
19. The force that holds blood drops together because of the strong attraction between their molecules.
20. Chemical luminescent test that reacts with hemoglobin and produces a yellow-green color under UV light when the
test is positive.

physical evidence and statements made by individuals involved with the incident.
3. An impact spatter pattern created by a force traveling at 5fps or less and producing droplets with diameters greater
than 3mm.
6. A pattern created by blood that is expelled out of the nose, mouth, or respiratory system as a result of air
pressure.
7. A bloodstain pattern formed by the movement of small or large amounts of blood as a result of gravity's pull.
8. The acute angle formed between the path of a blood drop and the surface that it contacts.
9. The process by which the edges of a stain dry to the surface in a specific period of time.
10. An impact spatter pattern created by a force traveling at 5 to 25fps and producing droplets with diamters between 1
and 3mm.
