The parents of missing teenager Amanda Dowler have told of their torment after news that the missing Soham schoolgirls were dead was announced.
Police have found no trace of Amanda, known as Milly, six months after she disappeared on her way home from school in Walton-on-Thames, Surrey.
Bob and Sally Dowler told ITV's Tonight with Trevor McDonald they fear she has suffered the same fate as 10-year-olds Holly Wells and Jessica Chapman.
Mrs Dowler said: "I think that she has been abducted and murdered and I've been through every possible scenario and played them all through time and time again, but that's the only one I seem to end up at each time.
"The not knowing is just awful because ... there is still that element of doubt. Has someone taken her, but is she still alive?
"As unlikely as you know that is, you can't help thinking, 'Oh please let that be the case'.
Mrs Dowler told the programme, which is broadcast at 8pm on ITV1, that cases of child abductions in the news have been very distressing.
Mr Dowler, his wife, a teacher, and Amanda's 16-year-old sister Gemma have been told by detectives that she is now almost certainly dead.
Detective Chief Inspector Craig Denholm, who is leading the investigation, says officers are working on live lines of inquiry and are still looking for a breakthrough.
