Forensic science

What is forensic science and how is it used to solve a crime? How do you know if a red stain is blood or ketchup, or whose blood it is? Can computers really recognise your face in a crowd? How do scientists decide how old bones are, and trace who they once belonged to? Explore the fascinating, and sometimes gory, world of forensics, where science helps crack the case. Learn why it is important to secure a crime scene, why fingerprints are critical clues, and how DNA sampling works. Find out how maggots can reveal how long someone has been dead, or how a single fabric fibre can lead to the murderer. From the scene of the crime to testing in the laboratory, you will get to know how all the clues are put together to tell a story and reveal the guilty person.
