Yes the tests were LCN and this is the outcome:
Forensic scientists, carrying out a review of the case in 2001, made an appalling blunder. They failed to test the tiny DNA sample found on Rachel’s body; had they done so they would have matched it to Napper’s, which by that time was on the database.
This wasn’t the only potential mistake by the Forensic Science Service:
The Times: February 22, 2007:
Hundreds of murderers, rapists and other serious criminals may have escaped prosecution because forensic scientists failed to test properly for DNA evidence for five years. More than 2,000 cases are being urgently reviewed — including that of Rachel Nickell, the former model murdered on Wimbledon Common — after the Forensic Science Service admitted that it might have missed crucial evidence.
The service, which carries out most DNA tests for police forces in England and Wales, expects to recover DNA in at least 200 cases where it had said that none existed.
The Times has learnt that chief constables believe that the total could be higher. The failure involves the processing between 2000 and 2005 of “low-copy-number” tests, used to identify microscopic quantities of DNA.
The Association of Chief Police Officers wrote to all police forces yesterday asking them to carry out a review of their serious crime cases.
Tony.
