You’ve probably seen a forensic scientist on television. Maybe they were called a “crime scene investigator.” They took evidence from a crime scene and analyzed it with scientific techniques. Perhaps they tested a bit of hair for DNA. Or matched fingerprints with a computer program. Or analyzed the chemistry of a soil sample to see where a crime was committed. And they did this really fast.
In reality, forensic science takes more time, and the results are often not as clearcut as what is shown on TV. This field also changes, as scientists discover new ways to get information out of seemingly unimportant bits found through criminal investigations.
