This is a<br />
Crime<br />
Scene!<br />
The Cabbage Caper is a<br />
murder mystery and you have been<br />
asked to help solve it! You will<br />
conduct an investigation by first<br />
learning what police on the scene<br />
have uncovered. Then, you will<br />
question suspects and look for clues<br />
that you can investigate back in the<br />
crime lab. As Chief forensic<br />
investigator, you will design and<br />
conduct experiments to determine<br />
“who done it”. Next, go to the Police Report<br />
Good Luck!<br />

John McCabbage - Commissioner<br />
Mr. Robert Worthington, a prominent<br />
citizen, was found murdered at his home.<br />
Robert Worthington<br />
The victim was discovered by the maid at approximately 10:00 A.M.<br />
this morning. He was found lying on the kitchen floor of his home with a<br />
vegetable knife in his back. The vegetable knife has a “strange bluishgreen<br />
stain” on the handle.<br />
The crime scene was secured to avoid contamination pending arrival of<br />
a full forensic team. Suspects were identified and scheduled for<br />
interview.<br />
An expert forensic investigator will be contacted to lead in the collection<br />
and analysis of evidence.<br />
I’m Commissioner John<br />
McCabbage but you can call me<br />
Mac! You must be my new Chief<br />
Forensic Investigator.<br />

When you arrive on the scene, the knife is<br />
still in Mr. Worthington’s back with a strange bluishgreen<br />
stain on the handle. Fingerprints are covered<br />
up by the stain so other methods will need to be used<br />
to determine the murderer(or murderers).<br />

The Butler greets you at the front door. He<br />
seems much too calm and professional<br />
considering the situation. You realize he has<br />
been trained to not show emotion, but still, he’s<br />
somewhat creepy.<br />
The Butler then tells you he was in the Billiard room<br />
polishing the cue ball when he heard a loud scream. When<br />
asked what he was using to polish the billiard balls he<br />
reluctantly tells you …<br />
“pickle juice”. “Master Worthington would<br />
not have approved”.<br />

The Cook had been assigned to<br />
prepare Mr. Worthington’s favorite<br />
vinegar and lemon dressing for the red<br />
cabbage salad. She claims Mr.<br />
Worthington was helping by cutting up<br />
the red cabbage. He often liked to help<br />
in the kitchen.<br />
Upon returning only moments later with<br />
a cup of vinegar from the pantry, she<br />
found Mr. Worthington on the floor with<br />
the vegetable knife in his back. She<br />
claims to have let out a loud scream!<br />

drains with lye. She said she decided to clean the<br />
kitchen drains and was just coming downstairs when she<br />
heard the scream. She claims that upon entering the<br />

The Nephew<br />
The Nephew claims he had been swimming in the salt<br />
water swimming pool and was drying himself off before<br />
going into the house when a scream filled the air. “I’d talk<br />
to the Gardener if I were you” said the nephew. “Before my<br />
swim, I saw him in the mud room scrubbing his hands. I’ve<br />
never trusted him.”<br />

Do only one test<br />
at a time<br />
Be sure to record your lab<br />
data in your Investigator's<br />
Notebook (crime lab data page).<br />
Because of your knowledge of chemistry it is your<br />
opinion that the green stain on the handle is the key clue in<br />
solving the mystery. Commissioner Mac has no idea what could<br />
have caused the stain. You explain to him that the murder<br />
weapon was being used to cut up a juicy red cabbage and that a<br />
few simple tests in the crime lab should indicate the murderer or<br />
murderers.<br />
Hint: red cabbage juice on the handle of the knife will turn a strange green color when<br />
mixed with certain substances<br />
Don’t Mess<br />
Up!<br />
Due to budget cuts at the crime lab,<br />
you may use only 5 DROPS of a solution<br />
and 2 DROPS of Red Cabbage Juice per<br />
test. Design your own tests and record all<br />
results in your Investigator’s Notebook<br />
(Crime <strong>Lab</strong> Data page).<br />
