THE son of a woman brutally murdered 15 years ago hopes a fresh police probe will finally bring her killer to justice.

Sean Shackleton, 24, was nine when the battered body of his mother Cheryl was discovered in Telegraph Hill Park, Brockley, but the murderer has never been found.

Now the grieving son says he is glad detectives have revived the murder investigation as he wants the killer to "get what he deserves".

Mrs Shackleton, 34, was discovered lying dead in the park by a dog walker in February 1991.

She died from severe bleeding, shock and a ruptured liver after being savagely beaten and sexually assaulted.

The killer has never been captured and last week police relaunched their investigation with an appeal on the BBC Crimewatch programme which led to 11 calls.

Mr Shackleton, who lives in west Yorkshire, also wrote to police chiefs, urging a fresh look at the case.

He says he is motivated by one thing justice for his mother.

Mr Shackleton said: "The main thing is my mum has been taken away and she will never be replaced. No-one can change that.

"I just hope this man is caught and gets what he deserves. He should be behind bars."

As part of the Crimewatch programme investigating officer Detective Inspector Des Nelhams took Mr Shackleton to the scene of his mother's death for the first time.

The engineer said: "It felt slightly surreal being there.

"I was not quite sure how to react."

Remembering his mother he added: "She was a very happy, bubbly and creative person, just a normal mum."

Mrs Shackleton suffered mental health problems later in life and took to travelling regularly around Europe.

Detectives say they are reopening the probe as they believe there are "fresh lines of enquiry" which have not yet been followed.

Police say the man they are looking for was white, aged 25 to 30, and of athletic build.
