The heartbroken parents of murdered landscape architect Jo Yeates have made a desperate plea for help, saying their daughter probably knew her killer.
David and Theresa Yeates urged anybody who knew somebody who had reacted strangely to the murder to come forward.
They said: "It would appear that the nation is shocked and appalled by what has happened to our daughter.
"Do you know someone who has been, somehow, justifying her being killed? Please help us identify the killer. Jo was probably acquainted with her killer."
Mr Yeates, 63, and his wife, 58, said they spent much of their time thinking how their daughter could have ended up dead by the side of a country lane.
Miss Yeates's snow-covered body was found on Christmas morning by a couple walking their dogs in Longwood Lane in Failand, North Somerset. She had been strangled.
The 25-year-old went missing on the night of December 17 after leaving friends in the Ram pub in Park Street, Bristol.
Reading a statement at the Thistle Hotel in Bristol, they said: "Nearly the whole country has been moved by the tragic events surrounding Jo's murder. Many of us are 'armchair detectives', but if this activity triggers anything please come forward.
"If you do know something and you do not come forward you are consciously hampering the apprehension of Jo's killer(s) and the perpetrator(s) is still free. You will also be prolonging the torment of Jo's family and friends."
Mr and Mrs Yeates were joined by Miss Yeates's brother Chris, 28, and boyfriend Greg Reardon, 27.
