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
sketching
 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
Label
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
Step 6: MEASURING FROM FIXED POINTS
A.
B.
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
FINAL 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
paper.
Catching
Errors: Can
you find at least 4
mistakes??
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
statement
 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
number
 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.
