The Bare Foot Bandet
The case of the Barefoot Burglar
In groups of 4 or five you are going to need to use your forensic knowledge to solve a crime.
Using the clues found at the crime scene, determine which of the four suspects is the "barefooted burglar"?
What do you think was the motive for this crime?
Write the results of your findings and convince a jury of your peers
The Crime
At approximately 7:15 a.m., Friday morning, Mrs. King, the science teacher, thought something was fishy as she walked down the hall and noticed that her door was open. She walked into her classroom and immediately discovered that the small aquarium had been broken and her prized gold fish were gasping in the sink. Beside the broken aquarium were the shattered remains of the pink piggy bank that had been on the shelf above the aquarium. A can of blue paint was spilled on the floor. Footprints of a barefooted burglar led to an open window. Bits of a white powdery substance were found next to the broken, empty, piggy bank. The only other item found was a half-eaten large chunk of chocolate candy.
When the police arrived they immediately began to gather forensic evidence.
| Peg the Leg Height: 5' Alias: Lucky Lady \ | |
| Peg is a librarian known for hanging horseshoes and four leaf clovers in her library. Employees say she is so superstitious she insisted on carpeting in the library instead of laying tiles so she would not step on the cracks. She wraps construction zone tape around open ladders so no one can walk under them. Cola bottles litter her office, which she drinks with chocolate chunks. Her teeth are chipped from knocking the bottles against them. She is always throwing salt over her shoulder for good luck and keeps a salt shaker in her purse. Her alibi is that she was busy closing open umbrellas the morning of the crime. | |
Height 6'6" Alias: Armchair Quarterback Jake the Jock is known for quoting statistics on every sport from boomerang throwing to sled dogging. His neighbors report that he is the neighborhood pitcher for baseball games. Last year a baseball hit him in the mouth and knocked out his front tooth. This has cramped his eating style of chocolate chunks, candied apples, and corn on the cob. His wife claims that on the morning of the crime Jake was rubbing his hands with cornstarch to keep them dry in preparation for an important baseball game. |
| Lou Lou Height: 5'3" Alias: Sweet Tooth | |
| Lou Lou is so addicted to sugar that she never leaves home without it. She loves to bake sweet things and has an entire pantry full of sugar bins. She claims to have been baking her famous chocolate chunk cookies the morning of the crime (although not a morsel of cookie or chocolate chunk was left when the police arrived.) Lou Lou rarely wears shoes, which often causes her to slip and break things, especially her collection of ceramic pigs. | |
- Sticky, 'swirl' fingerprints were lifted from the aquarium and piggy bank.
- The painted footprints were measured and were for 26cm feet. ( size 8)
- The chunk of chocolate candy was collected for examination. It appeared there were teeth imprints.
- The white powdery substance by the piggy bank was carefully placed in a plastic bag and taken to the forensic chemist for identification . It had very small grains and when mixed with Iodine it reacted making the colour brown. It did not have a smell.

Forgery
A. Top Of Letter Analysis
1. Sign your name on a sheet of writing paper, and get someone else to try to copy it.
2. Place the tracing paper over both signatures, and make a dot at the top point of each letter – for both signatures
3. Join up the dots for both signatures to get two zigzag lines across the signatures. Are the lines the same?
B. Bottom of Letter Analysis
4. Put some fresh tracing paper over both signatures.
5. Put a dot at the bottom of each letter.
6. Join up the dots to make zig zag lines. Are the lines the same
C. Slant Analysis
7. Put a fresh piece of tracing paper over both signatures.
8. Mark a vertical line down through the middle of each letter (using a ruler), slanting it in the same direction as
the letter.
9. Compare the set of lines for both signatures. What do they tell you.
Get someone to try to forge your signature and then try both of these methods to analise it.
a) The size of the letters – all big, all small, mixed?
b) where they dot the i – over the top or off to the left or off to the right, or not at
all
c) how they cross their t – straight, angled up or down, where on the t stroke it
is crossed
d) the slant of the letters (use a ruler) – forward, backward, upright, mixed
e) are there breaks in words, or are all the letters in the words joined up
f) how big are the spaces between the words
g) the length of stalks on y, q, p, below the lines – long or short
h) the height of tall letters (t, h, l) – tall or short

Foot Print's
1. Have the students in your group remove their shoes and measure their height.
2. Measure the length of the adult's left foot from the wall to the tip of the big toe.
3. Examine the numbers. Do you see the pattern?
4. Divide the length of each person's left foot by his/her height. Multiply the quotient by 100. What do you get? You many also want to use the calculator on a computer for this activity
The results of your calculations should be about 15, illustrating that the length of a person's foot is approximately 15 percent of his her height.
