Extra Credit Responce. Science Related to T.v. show episode.

I watched the show Law and Order; Special Victims Unit this afternoon. The episode was about a serial rapist. Generally, the detectives would take fluids or finger prints left on the victim and match it to their suspects DNA. If there was a match, you had your Perp. However, in today's episode, the Perp left behind no fluids nor finger prints on his victim's. Instead, the forensic scientist was able to locate hair fibers on the victim's body and was then later able to match those hair fibers to the detectives suspect. Without science all police work would be a lot more difficult !
