35 years ago, Prof Sir Alec Jeffrey's discovery of DNA genetic fingerprinting at the University of Leicester changed policing and the criminal justice system forever.

Leicestershire Police were the first force in the world to use DNA fingerprinting to solve the murder of two Leicestershire schoolgirls. Also in Leicester, a form of DNA fingerprinting was used by Professor Turi King in the King Richard III case.

For the first time, to mark the anniversary of the publication of Sir Alec Jeffreys’ discovery, the mothers of the two girls, the man who led the police investigation and Sir Alec came together at an event organized at the University.

Martin Ballard tells the story of the discovery, it's groundbreaking use and it's legacy and talks to all of those involved.
