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 goldfish 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 spilt on the floor. Footprints of a barefooted burglar led to an open window. Bits of a white powdery substance was 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.
When the police arrived they immediately began to gather forensic evidence.
- Sticky fingerprints were lifted from the aquarium and piggy bank. The painted footprints were measured. 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.
Jake the Jock
Height 201 cm
Alias: Armchair Quarterback
Jake the Jock is known for quoting statistics on every sport from boomerang throwing to sledge dogging. His neighbours report that he is the neighbourhood 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.
 Height: 152 cm 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. | ||||
Lou Lou Height: 160 cm 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. Evidence: | |
- Fingerprints: Sticky, 'swirl' fingerprints were lifted from the aquarium and piggy bank.
- Footprints: The painted footprints were measured and were for 26 cm feet.
- Teeth: The chunk of chocolate candy was collected for examination. It appeared there were teeth imprints.
- White Powder: 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.

Findings: ( what did you find. Summarise what you have written in the table above)
What I got first from the table that everyone had a fingerprint and evidence for white powder. But I hadn't got a shoe size from any of the suspects, because they were all barefoot. Dan's mouth was like a beaver. Peg's mouth was chipped. Jake's front tooth was knocked off at a baseball game. There weren't any mouthprints for Lou.
Verdict: ( who is the burglar and why)
I think that the burglar is Dan the Man because he had a swirl fingerprint and he was the one who was stealing the giant chocolate kisses.
