Crime Scene 1 - The Case of Lois McArthur

All the intrigue, mystery and excitement of an actual case arrives at your school with Crime Scene 1 in a cost-effective way!~Crime Scene costs a fraction of the price on individual kits sold by others!~Crime Scene is a single scenario that relates biology, chemistry and physics tools to criminal investigations.

Each student in three classes of 24 will be able to conduct the following tests:

Hair Analysis

The sample you are given has far more hair than any crime scene would have.~Limit the sample size for students to one strand of hair of each suspect.~Students should look at texture, color and scaling of the individual hair samples under low power of a microscope.~A dissecting scope is also useful

Blood Analysis

~ Six blood samples and anti sera for A, B, AB and O blood types.

All blood samples are simulated.~No real human or animal blood is used.

The blood samples of the suspects and the victim are large enough for two classes of twenty-four students working in pairs.~You should tell the students that the blood sample from the suicide note has been reconstituted for testing purposes.~Obviously, the culprit would not knowingly leave a blood sample for testing!

Fiber Analysis

Packets of fibers for microscopic analysis.

Follow the same procedures as the hair analysis.

Fingerprints

Copies of fingerprints found at the scene and five suspects.

The finger print analysis requires that the print of the culprit left on the note must provide at least 10 identical points of identification compared with a print of one of the suspects.~It is not enough to get one or even 5 common points.~A court requires 10 points of commonality.~Your students may find more, but 10 points of commonality is the minimum.

Handwriting Analysis

Samples of the victim, suspects and suicide note.

Handwriting should follow the same quest for similarity as fingerprints.~You will find that this is much more difficult since the person who wrote the note may wish to hide their identity.~Fingerprints cannot be altered in this way.

Rap sheets, directive from the police chief, reference materials are provided in a bound booklet for easy duplication.
