RACHEL Nickell's killer has been brought to justice 16 years after she was brutally stabbed and assaulted in front of her young son.

Convicted sex killer Robert Napper, who used to live on Plumstead High Street, pleaded guilty to manslaughter at the Old Bailey on Thursday (Dec18).

His plea was accepted on the grounds of his diminished responsibility.

Forty-two-year-old Napper, who is a patient at Broadmoor, admitted attacking Miss Nickell in front of her two-year-old son, Alex, at Wimbledon Common on July 15 in 1992.

Judge Griffiths Williams told him he would be held in Broadmoor top security hospital indefinitely and added: "You are on any view a very dangerous man."

The plea means one of the most high-profile crimes ever dealt with by Scotland Yard has finally been solved.

Napper was sent to Broadmoor after he stabbed to death Samantha Bissett, 27, and sexually assaulted and smothered her four-year-old daughter Jazmine at their Plumstead flat in November 1993.
