This workbook is designed to assist the Crime Scene Analyst,
Technician or Investigator in documenting bloodstained patterns
that are located at the crime scene or on bloodstained items that
are submitted for an analysis. It is also designed to assist the
Crime Scene Analyst, Technician or Investigator in reconstructing
or analyzing a bloodstained crime scene or a bloodstained item for
which a bloodstain pattern analysis is requested The documentation
could be accomplished with overall, midrange photographs and
close-up photographs with 2, 3 or 6 centimeter stick-on tapes that
should be placed in the center of each rectangular area. The
documentation should also consist of notes and rough sketches with
measurements. The close-up photographs of the rectangular areas
with the 2, 3 or 6 inches stick-on tapes that were placed in the
center of those areas should be taken with a parallel film /camera
plane. The stick-on tapes should be labeled according to the
surface on which they would be placed. Example: West wall of living
room #1 (ww of lr #1) and west wall of living room #2 (ww of lr #2)
etc. The number of close-up photographs would be determined by the
number of rectangular areas with the stick-on tapes. Example: At
least ten (10) close-up photographs should be taken if ten (10)
stick-on tapes were placed on the bloodstained surface. The
bloodstain pattern reconstruction or analysis should be done by
first recognizing and or identifying the many different types of
patterns in a bloodstained scene or on a bloody item. The next step
should involve the reconstruction of the points or areas of
convergence and origin and then a determination of how the other
patterns were most likely created. The workbook contains several
tasks and assignments that would provide the student with the tools
to accomplish the documentation and analysis. The Crime Scene
Analyst, Technician or Investigator after successfully completing
the workbook / workshop should be aware that: 1.0 Single drops of
blood in a crime scene or on an item were influenced by the surface
from which the blood fell (the volume); the diameter, the shape,
the impact angle, the scalloping of the perimeter and the direction
of travel of the dropped blood that impacted the target surface
(the volume, the height from which the blood fell, the texture of
the target surface on which the blood fell, the angle of the
targeted bloodstained surface and the horizontal speed of the
source that issued the blood). 2.0 Numerous drops of blood in the
same pattern in a crime scene or on an item were influenced by the
force or the impact (less than 25 feet per second - dropped blood
and cast-off bloodstain); (25 to 100 feet per second - medium
velocity bloodstain); (over 100 feet per second - high velocity
bloodstain); projected blood (arterial bleeding); transfer of blood
from one object to another (contact or transfer bloodstains,
imprint bloodstains, smears or swipes and wipes); large volumes of
blood (splashed or pooled blood) 3.0 The reconstruction or analysis
of the points or areas of origin could be determined by strings,
scaled drawings or calculations. The interpretation of the other
patterns (non impact) along with the Medical Examiner's autopsy
report should allow the crime scene analyst, technician or
Investigator to complete a bloodstain pattern analysis report and
if possible explain and or testify to the sequence of events that
occurred at the crime scene.
