Future of Forensics
U.S. FBI
The U.S. FBI have been using various sciences to solve cases and prevent further crime. FBI employers provide forensic exams, technical support, skilled witness testimony, and advanced training to other investigators around the world. Whether it’s examining DNA to help determine guilt or innocence,
analyzing the fingerprints left at a crime scene, or linking exploded bomb fragments to terrorists, the employers of FBI are dedicated to using the technologies of science to protect and defend the society. (Source: FBI Laboratory Services)

Watson and Crick
Watson and Crick's used sticks and balls to build a model of the DNA molecules, but they kept manipulating the model because the nitrogenous bases did not fit. Finally with the help of Franklin and Wilkins, they discovered the double helix structure of DNA. (Source: Discovery of DNA Structure and Function: Watson and Crick)

DNA Fingerprinting
Alec Jeffreys' discovery of DNA fingerprinting has led to a huge advancement in forensics. Scientists can now be given a DNA sample and they can find matches of the DNA if the person has been convicted of felony. (Source: DNA Fingerprinting is Everywhere!)

PCR
The discovery of PCR has greatly aided forensic scientists because when given a single strand of hair, scientists can extract the DNA and produce many replicas of the same DNA efficiently and affordably. (Source: PCR)
