Nisha Patel-Nasri was a business owner and special constable in the Metropolitan Special Constabulary who was stabbed to death at her home in Wembley, London, on 11 May 2006.
Police described her murder as "atrocious and horrendous" and it was included in a list of ten prominent police deaths between 2001 and 2006 by Guardian Unlimited.
Two men, heroin dealer Roger Leslie and bouncer Jason Jones, were convicted of Patel-Nasri's murder, as was her husband, Fadi Nasri, who had organised the murder in order to claim her life insurance. The trio were sentenced to life imprisonment.
