5. Make tent cards and
number them to mark
all evidence located
on the crime scene.
Once you have been
separated into groups
I will tell you how
many tent cards your
group will make.
Do NOT begin making
cards until you have
been told how many
to make!!!
Tent Cards – Marking Evidence
6. Record a pictorial view of the scene.
Record items of evidence.
One person in your group may pull out
their phone to take photographs of the
crime scene.
Make sure I check them before you move
on.
Photograph the Scene
7. A rough sketch should be
completed by the crime
scene technician to
demonstrate the layout of
the crime scene and to
identify the exact position
of the deceased victim or
evidence within the crime
scene.
Make sure ALL
requirements are included
on your sketch, just like
the sketch you did last
week.
Sketch the Scene
8. Must provide all the details necessary to
complete a finished drawing
Must identify every object in the room
Need to be to scale
Needs to have measurements (have someone in
your group verify this).
Needs to be marked “N” for North to orient the
drawing
Needs a legend to explain any symbols that are
used to identify various objects (In small
areas, various objects may be lettered or
numbered and keyed in the legend)
Sketch the Scene
9. In this case and at this crime scene, the note taker has two jobs.
◦ The first job is taking notes over crime scene. Make
notations over placement of objects, the position of the
body, blood spatters, bugs or insects that are on the
body, etc. Anything and everything is note-worthy.
◦ The more detailed your notes are, the better off you are.
◦ The notes taken will help to reconstruct the crime scene
after it is longer available to you.
◦ Notes should contain any of your own thoughts and any
“memory joggers” that will help you remember the
specifics about the case.
◦ Be sure to work closely with the crime scene sketcher
and the photographer so that nothing is missed.
◦ Notes need to be typed up and placed in the file so that
they do not get lost. They are a very important
permanent record about the crime scene.
Note-taking
10. The second job is that you will do is provide
leadership for your team. You will be the
one who assists the sketcher on double-
checking measurements. You will be the
one to question the photographer to make
sure that all the evidence, strange marks, or
footprints were photographed. Once the
POE has been established, photographs
have been taken, and notes have been
written, it will be your responsibility to
make sure that your evidence collector does
a thorough and proper job. If asked, you
will be the one who holds the envelope
while the evidence is placed into it.

21. Crime scene reconstruction is the use of
scientific methods, physical
evidence, deductive reasoning, and their
interrelationships to gain explicit knowledge
of the series of events that surround the
commission of a crime.
It is a disciplined and principled approach
towards objectively understanding a crime
scene.
Using evidence found at a crime scene the
incident can be reconstructed to determine
what happened, and possibly find more clues.
Crime Scene Reconstruction
22. Specific Incident Reconstruction (Traffic
Accident, Homicide, Bombing, etc.).
Specific Event Reconstruction
(Sequence, Direction, Condition, Relation,
Identity).
Specific Physical Evidence Reconstruction
(Firearms, Blood, Glass etc.).
Types of Crime Scene
Reconstruction
23. The pattern selected will normally depend
on the size and locale of the scene and
the number of collectors participating in
the search.
