About this image

The use of DNA evidence has helped the police solve many crimes that would otherwise have gone unsolved. It is an important tool in fighting crime and keeping our communities safe. The use of DNA evidence in crime solving is not a new development. In fact, the first case where DNA evidence was used to convict a murderer dates back to 1987. That case involved a young woman named Dawn Ashworth who was raped and murdered in Leicestershire, England. Investigators were able to obtain a sample of the killer's semen from the victim's body and used it to identify the killer, Colin Pitchfork. He was eventually convicted and sentenced to life in prison. One of the main concerns with DNA evidence is that it is often mishandled or misinterpreted. This can lead to innocent people being convicted, or guilty people going free. There have been many cases where DNA evidence has been used to convict someone, only for them to be later exonerated by new evidence.
