Double child killer Colin Pitchfork will be kept off the sex offenders register when he is released from prison, causing outrage among his victims' families.
The 61-year-old, who raped and killed 15-year-old schoolgirls Lynda Mann and Dawn Ashworth in the 1980s, also 'plans to change his name' after serving 33 years behind bars.
He could be freed from HMP Leyhill in Gloucestershire at any moment after a Government-backed appeal against the Parole Board's decision to release him was rejected this week.
And the killer, who now calls himself David Thorpe, will be well within his rights to change his name - yet again - by deed poll, for just £33.
Dawn's mother Barbara, 75, told the Daily Mirror: 'Words fail me. A psychopath like him shouldn't be allowed to change his name.

'He'll be able to walk in the pub as a new man, with a new identity.
'It's absolutely shocking that he can do it legally. People need to know who he is and what he has done.
'He is a very dangerous man – he shouldn't be on the streets at all. He shouldn't be able to hide who he is.'
Pitchfork can dodge the sex offenders list because of a legal loophole which dictates that it cannot include anyone convicted of sex crimes before 1997.
Its measures would have required him to keep police informed of any change in address or personal circumstances, including a name change.
However the Government said Pitchfork will still have to abide by tough conditions -including being required to wear a tag on his release, live at a specific address and take a lie detector test.

But former Labour Home Secretary Lord David Blunkett said: 'I was deeply disappointed that the Parole Board did not reverse their earlier decision to release Pitchfork, given the heinous nature of the crimes he committed.
'The least that can now be expected to secure the confidence of the public and place their safety as the key priority on his release, is to place him on the register with all the consequent checks and restrictions which this brings.'
Barbara, who lives in Liskeard, Cornwall, added: 'It's shocking that he is not on the register. I assumed he would have been.
'I'm convinced he will do all he can to be around children.
'He has been refused that opportunity while he's been locked up.
'But that will change when he walks the streets again He's so arrogant – a psychopath who thinks he is above it all.
'The public must be protected from him and every safeguard must be put in place.'
Pitchfork became the first man convicted of murder on the basis of DNA evidence in 1988 after admitting two murders, two rapes, two indecent assaults and conspiracy to pervert the course of justice.
Lynda's sister Sue Gatrick, 55, exclusively told MailOnline this week: 'He could kill again. He could rape again. And he could put someone else through it. It is just not right.
'There should be pictures of how he looks now – because he has changed so much – plastered everywhere. He should have it tattooed on his head that he is a nonce, that he is a danger. Then he should be castrated.
'He cannot change his sexuality. He is not going to change his personality or who he is.
