CRIME BUSTERS

Crime Busters

Part 1 FIBER

·         Keep Suspect at scene of the crime

·         To find a suspect he/she should AT least have the same textile fibers on their clothes like the ones found at the scene of the crime

·         The Fibers should have the same or variation of color, the same amount of fibers found, location of fibers at crime scene at on victim, and the number of different fibers between the crime scene and suspect

·         A fiber is the smallest unit of a textile material that has a length many times greater than its diameter.

·         Fibers can be from plants, animals, or be man-made

Part 2 DNA

·      Ex: if blood type O is found at the crime scene, you now know that the criminal has type O blood. However, 45% of Americans have type O blood. Next, if a blonde hair is found, you now know that the criminal is blonde and has O type blood. If there are unique footprints made from the bottom of a Nike shoe, then you’re much closer to finding who the criminal is because you now have a specific piece of information.

For example, say there are five suspects.

Suspect 1 has blonde hair, was wearing a set of Achilles shoes and had blood type A. since only the blonde hair matches up, this person can’t be the suspect. Suspect 2 has black hair, blood type AB, and was wearing Nike sneakers. Only the Nike sneakers match up. Suspect 3 has blonde hair, dirty Nike sneakers, and Blood Type O. Most DEFINITLY this person is the suspect. However, Suspect 4 and 5 also have the same attributes, so 3 suspects are left with the same match-ups.

        Now you have to do DNA testing. Take the hair that was found and take the three suspects hair. Next, put them each under a microscope. You might see that one of the hairs has no relationship to the first at all. SO the last two could be tested by sugar in the blood. THEN you can figure out who is the suspect.
