There can be no doubt that DNA has been a huge game changer in solving crimes. And in particular cold case crimes as shown in this four part true crime drama by the BBC.
The story evolves around the brutal murder and rape of three teenage girls in Port Talbort South Wales in 1973. With similarities to the hunt for the Yorkshire Ripper the only options were endless hours of door to door searches, index systems and eye witnesses and a hope that they somehow come up with a credible suspect. It's no wonder so many innocent people ended up in jail for crimes they didn't commit.
We move on 30 years and the still early days of DNA and the cold case detectives now can use samples to find matches in the DNA database, and before long a prime suspect emerges.
With nice attention to the 1970s it's a really interesting insight into how policing has changed over the last 30 years.
Despite a dodgy Welsh accent Phillip Glenister does a decent job as the lead detective to help put to rest a crime that many thought would never have been solved. 7/10.
