You don’t have to be an artist!
Fast, Tidy, Accurate!
 Evidence
needs to be collected
and analyzed by technicians, so
there will not be a lot of time for
 Measurements need to be made
quickly, but without disturbing the
evidence or contaminating the
crime scene.
Where do I start?
Step 1: Draw a rough outline of the
area- include windows
(represented by the rectangles)
and doors (represented by
openings in the outline)
 Step
2: Measure the room or
space in which the crime
occurred. Label the dimensions
on the sketch
Step 3
Sketch in the furniture and location
of evidence using basic shapes
Step 4
Label each item in the diagram with a
number or letter, then write the name
in a key.
Step 5
the diagram with the
date, time, location, and
victim’s name (if known)
Note: An unknown victim is
commonly given the name
of John Doe or Jane Doe
Make two measurements from fixed
(not moveable) points to each piece
of evidence
These measurements are noted on a
separate document, and not on
actual sketch
A. There is never a second chance to
sketch a scene, so all information must
be noted before leaving
B. The final sketch will be completed after
leaving the crime scene.
C. The final sketch will be drawn with a
ruler to scale and may be done on graph
Errors: Can
you find at least 4
Write your responses on
the handout
 Sketch
crime scene complete with
label, dimensions, and key
 Answer the questions on the back
 If you are done or waiting, work on
the vocab crossword- use your
notes and returned work to help!
 Both the sketch and crossword will
be collected and graded
 There will be time to finish both
activities tomorrow- We will be
stopping at 11:35 today for a quick
summary of today’s lesson
Thumbs Up / Thumbs Down
Give a thumbs up if you agree with the
 Give a thumbs down if you disagree with
the statement
 Wait to give the thumbs up or thumbs
down until I say
 A crime
scene must be sketched
carefully since you will never
have the chance to sketch the
scene again
 When
making measurements
to pieces of evidence, you can
measure from two objects like
a TV and a bookshelf
 When
labeling objects in a
crime scene, you label
evidence and other items in
the room with a letter or
 The
sketch made in the field will
stay “as is”- no changes,
modifications, reproductions, or
final sketches will be made
 When
sketching in doors and
windows for the outline, it is
important to include all of them,
even if they are away from where
most of the evidence is located.
