The parents of murdered April Jones fear that killer Mark Bridger may never reveal where the body of their daughter is.
Bridger, 47, kidnapped April before sexually abusing her, murdering her and then disposing of her body last October.
Parents Paul and Coral Jones told The Sun that there is "no way" the killer will tell them where their daughter is - and they will not give him the satisfaction of asking.
April's blood and bone fragments were found in Bridger's rented cottage in Cienws, mid-Wales.
The couple hope the coroner will give them the bone pieces in order to carry out a symbolic funeral, the newspaper reported.
They said one of the most distressing moments during the trial was hearing Bridger say their daughter's name and refer to her as "little April".
The couple had known the "child-murdering coward" whose son is at the same school as their children but never had any reason to think he was "weird".
April's grandparents Dai and Linda Smith also told of their anger towards Bridger, during an interview with Welsh television channel S4C.
A few weeks before April's death, her grandparents had taken her to a local beach.
Bridger, a former slaughterhouse worker, was given a whole life sentence by trial judge Mr Justice Griffith Williams.
April had been playing with friends close to her home on the Bryn Y Gog estate in Machynlleth, mid-Wales when Bridger enticed her into his car.
Police officers found numerous indecent images on his computer, as well as pictures of young female murder victims, including Holly Wells and Jessica Chapman, the victims of Soham killer Ian Huntley.
On the day April was abducted, Bridger had viewed online photographs of a young girl and a pornographic cartoon depicting the apparent rape of a physically restrained and visibly distressed girl.
