Every piece of evidence in a case is essential as well as every element of the case. For instance, a solid investigation has not only witness statements, confessions, and other proof but also physical evidence.

Today, DNA evidence is some of the most crucial and confirming proof out there and the technology for it is advancing all of the time. But when was DNA evidence first recognized as a helpful forensic and investigative tool?

The discovery of the benefits of analyzing and profiling DNA samples can be attributed to Sir Alec Jefferys in 1984. The first cases that used DNA analysis was in 1986. The cases were rape and murder cases. There were two, young victims, Lynda Mann, and Dan Ashworth. Investigators knew about Jefferys' discovery and requested that he assist in the investigation. The incidents had occurred two and a half years apart but the similarities in the cases must have prompted police to think the murders may be linked. Law enforcement already had their eye on 17-year-old named Richard Buckland.

Thanks to Jefferys authorities knew they were looking for a Colin Pitchfork not Buckland. Pitchfork was arrested and convicted making this the first case where DNA analysis solved it.
