The partner of murdered Rachel Nickell has instructed lawyers in a bid to bring the police to account for their failings in the case.
Andre Hanscombe's son, Alex, witnessed the murder and sexual assault of his mother on Wimbledon Common on July 15, 1992 at the hands of Robert Napper.
Napper was convicted in December last year, 16 years after Miss Nickell's death, while Colin Stagg spent 13 months in prison on remand after being wrongly charged with the murder.
Law firm Hickman and Rose said: "We are advising on remedies arising from the police failures to detain Robert Napper prior to the murder of Rachel Nickell and the subsequent long delay in establishing his responsibility for the murder.
"All possible avenues will be explored for bringing the police to account for their many failings."
Solicitor Kate Maynard said her client was not motivated by a desire for compensation but wanted "accountability and answers".
She said no decisions had yet been made about how to pursue the issue but added that a formal complaint to the police or civil proceedings "have not been ruled out".
