AT THE SCENE OF A CRIME
Your phone rings. The police officer says someone broke into a store and took some expensive items. They need you right away. It is your job to study the whole scene for clues that will help catch the thief. You are a crime scene investgator, and the game is on.
Outside the store, you see a broken window, some glass on the street, shoeprints, and marks made by a vehicle's tires. You look at the shoeprints. They're large, so you're likely looking for a man. You photograph the shoe's pattern. This can tell you the type of shoe. You then measure the space between the shoeprints. You now know how long the man's steps were. This gives you an idea of how tall he was.
As you follow the shoeprints over to the tire marks, they get farther away from each other. They lead to the passenger's side of the vehicle. Now you know the man probably didn't work alone. You photograph the tire marks. They can help you find out what type of vehicle it was, and the direction it went in.
On the Case
The most important clues will come from a person's body. The person who broke in left a little of himself behind. In the store, you find some fingerprints. Using a computer, you can compare these prints against millions of others.
In the store, there is a lot more glass. Then you find something else—a hair. You keep this because you know hair contains a person's DNA. You can compare this with other people's DNA, too. If you find a match for the fingerprint or the DNA, you will know who was in the store.
Will you find the thief? You now have a lot of information, so it's possible. For a crime scene investigator, it’s all in a day's work.
How would the author probably answer the question, “Will the thief be caught?”
A.Yes, he will.
B.Maybe.
C.I don’t think so.
D.No, he won’t.
