SKETCHING A CRIME SCENE

• You dont have to be an artist!

3
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.

4
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)

5

• Step 2 Measure the room or space in which the
  crime occurred. Label the dimensions on the
  sketch

6
Step 3

• Sketch in the furniture and location of evidence
  using basic shapes

7
Step 4

• Label each item in the diagram with a number or
  letter, then write the name in a key.

8
Step 5

• Label the diagram with the date, time, location,
  and victims name (if known)
• Note An unknown victim is commonly given the
  name of John Doe or Jane Doe

9
Step 6 MEASURING FROM FIXED POINTS

1. Make two measurements from fixed (not moveable)
   points to each piece of evidence
2. 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.

15

• Catching Errors Can you find at least 4
  mistakes??
• Write your responses on the handout

16

• 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 1135 today for
  a quick summary of todays 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

18

• A crime scene must be sketched carefully since
  you will never have the chance to sketch the
  scene again

19

• When making measurements to pieces of evidence,
  you can measure from two objects like a TV and a
  bookshelf

20

• When labeling objects in a crime scene, you label
  evidence and other items in the room with a
  letter or number

21

• The sketch made in the field will stay as is-
  no changes, modifications, reproductions, or
  final sketches will be made

22

• 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.
