Soham murderer Ian Huntley has apparently expressed his remorse at having killed schoolgirls Holly Wells and Jessica Chapman.
Huntley, 44, is serving a life sentence after being found guilty of killing the girls, who went missing from a family barbecue in Soham, Cambridgeshire, in August 2002.
After a two-week hunt to find the youngsters, their bodies were found near an air base at Mildenhall in Suffolk.
The Sun reports Huntley has recorded a confession for the killings while behind bars, and has accepted he is "never getting out".
The paper reports the former caretaker as saying: "I am genuinely, genuinely sorry and it breaks my heart when it is reported I have no remorse; that I relish something. I do not.
Huntley's then girlfriend Maxine Carr was sentenced to three-and-a-half years in prison in 2003 after being found guilty of conspiring to pervert the course of justice after giving him a false alibi.
