FBI Rapid DNA will take a big bite out of violent crime
FBI plans 'Rapid DNA' network for quick database checks on arrestees
Though DNA has revolutionized modern crime fighting, the clues it may hold aren't revealed quickly. Samples of saliva, or skin, or semen are sent to a crime lab by car (or mail), and then chemists get to work. Detectives are accustomed to waiting days or weeks, or more, for the results. Some labs are so backed up, they only take the most serious crimes. Some samples never get tested. But a portable machine about the size of a large desktop printer is changing that. A "Rapid DNA" machine can take a swab of DNA, analyze it and produce a profile of 20 specific loci on the DNA strand in less than two hours. Some local police departments and prosecutors have been using Rapid DNA machines for about five years to solve crimes.
