Ian Huntley has been in prison since 2005 for the murders of 10-year-old Jessica Chapman and Holly Wells
The murders of Holly Wells and Jessica Chapman scarred the nation in August 2002.
The two girls, both aged 10, were reported missing on 4 August and their bodies were found nearly two weeks later on 17 August by a farmer.
Ian Huntley, their primary school's caretaker, denied everything - but forensic science was able to prove that he was guilty and he was sentenced to life imprisonment in September 2005.
One of the worst things about the Soham murders, as they've now been called, was the fact that Huntley seemed completely lacking in remorse, only admitting manslaughter and trying to make out that the girls had been killed accidentally.
He never once apologised for his horrific actions - until now.
Huntley, now 44, has recently been recorded from behind bars, finally pleading for forgiveness 16 years after the deaths of Holly and Jessica.
In a leaked recording to The Sun, Huntley can be heard apologising, saying: "What I will say is that I am so terribly, terribly sorry for what I have done."
Huntley, originally from Grimsby in Lincolnshire, went on: "I know the people of Soham took me into their community, they trusted me, gave me a job and a home, and I betrayed them in the worst possible way.
"And I am sorry for what I have done, sorry for the pain I have caused to the families and friends of Holly and Jessica, for the pain I have caused my family and friends, and for the pain I have caused the community of Soham.
"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."
The murderer also revealed that he thinks about the girls all the time, saying: "I can’t change anything. I cannot remove that day from history, what I have done.
"I know those girls would be 26 this year with families of their own, jobs and lives. I thought about them when they were turning 21 and when they were turning 18.
"I know no matter what I say that people are not going to think any better of me... But I would much rather people have the truth about how I feel. I have nothing to gain by saying these things. I know I am never getting out. I have accepted that from day one."
Huntley also revealed that he would never apply for parole.
