BRITAIN’S youngest female murderer faces the rest of her life in jail after plotting to kill another inmate.
Sharon Carr — dubbed the Devil’s Daughter — lost a legal fight to have prison restrictions on her eased.
It means Carr, who was just 12 when she knifed stranger Katie Rackliff, 18, to death in 1992, will continue to spend much of her jail time in solitary.
Her case was derailed after it was discovered she fantasised about murdering an inmate.
High Court judge Mr Justice Julian Knowles wrote: “[Carr] had disclosed thoughts of wanting to murder another resident by splitting her head open with a flask and throwing her down the stairs to snap her neck.”
Carr, now 40, was convicted of killing Katie in 1997 and sentenced to life. Her 12-year minimum tariff has long since expired but she is thought too unstable to be released and remains in HMP Bronzefield, South West London.
'INTENSE RELATIONSHIPS TURNED TO VIOLENT FANTASIES'
She launched a legal challenge against her restricted prisoner status saying it was approved at a private meeting she should have been allowed to attend. But Mr Justice Knowles denied permission to seek a judicial review.
It means she now faces being locked up in a high security unit indefinitely.
In his judgment, Mr Justice Julian Knowles ruled the public would be at risk if Carr was moved to softer surroundings.
He heard Carr tended to form “intense relationships with females that turned into violent fantasies when thwarted”.
Schoolgirl Carr picked teenage hairdresser Katie at random as she walked home from a nightclub in June 1992.
She then stabbed her thirty-two times and so ferociously police believed they were hunting a man.
Two years later, she struck again and attacked another schoolgirl with a knife in Camberley, Surrey.
But while in a young offender's institute for the knife attack - where she tried to strangle two nurses - Carr began bragging about killing Katie.
Police were alerted and she was convicted in March 1997.

The ruling was welcomed by campaigner Lynne Baird, 63, who said: “Carr shouldn't have the opportunity to even smell freedom.
"I don't doubt for a second that she would kill again if she had the means.
“The best thing to do would be to throw away the key.”
