The crux of modern forensics is DNA. DNA has been around for a long time. But how did it find its place in solving crimes? It started with two rapes and murders of teenage girls along footpaths in England. Authorities thought they found their man, but a Geneticist named Alec Jeffreys showed them this was not the case. Today's story is the first time mass DNA screening was used, someone was convicted due to DNA evidence, and someone was exonerated due to DNA evidence... all in the same case.
