Twisted Bernadette McNeilly, 55, subjected 16-year-old Suzanne Capper to a shocking ordeal in one of Britain’s most sadistic murders.

But prison chiefs reckon she has been rehabilitated and have freed her after 21 years.

Her release will devastate Suzanne’s family.

The teenager was stripped, plunged into a bath of disinfectant and forced to listen to recordings of McNeilly imitating Chucky, the demonic doll from horror film Child’s Play.

Mum-of-three McNeilly and her drug-crazed gang beat their helpless victim, shackled her to a bed, injected her with drugs and pulled out her front teeth with pliers at a house in Moston, Manchester in December 1992.

Suzanne was dumped in a wood, doused in petrol and set alight.

After being spotted by a passing motorist, she was taken to hospital and survived for four days – long enough to name her attackers and land McNeilly – then 24 – and three of her five evil sidekicks life sentences.

The Daily Star Sunday has been told that while behind bars at HMP Durham, McNeilly enjoyed a romance with Moors murderer Myra Hindley.

She was also “good friends” with Gloucester House of Horrors monster Rose West.

She went on to have an affair with the prison governor Mike Martin, who resigned his post before disciplinary action could be taken.

McNeilly enjoyed scores of day release outings from HMP Styal in Cheshire after a High Court judge cut her minimum 25-year sentence in 2012.

But she has now been granted parole after a senior prison officers’ report called her a “model prisoner” and “full of remorse”.

She has been given a new name and a makeover and is living in a secret location in north-west England.

Last night ex-prisoners who served time with McNeilly called her release a “shocking blunder” and dubbed her “dangerous and manipulative”.

An ex-con who spent her stretch at HMP Foston Hall in Derby and HMP Styal said: “All I can say is no human being should have to breathe the same air as that animal.

“She told me it was some guy murdered that girl and that she was in the wrong place at the wrong time so she is not sorry for what she did.

“She wants people to feel sorry for her but she is dangerous.

“She would do anything to make her jail life better and was in lots of sexual relationships with women and men in jail.

“She can be very manipulative and clever.”

Another prisoner told us: “She is not sorry.

“She may have portrayed herself as the model prisoner but I believe she will never control that demon inside her and that makes her a very dangerous woman.”

Sex with ‘Chucky’ killer; Prison boss resigns over his secret affair.

A PRISON governor has resigned after he was caught having an affair with a murderess in the same jail as Rosemary West and Myra Hindley.

Married Mike Martin, 42, was so besotted with notorious “Chucky” killer Bernadette McNeilly that he continued sending her love letters even after he moved to another prison.

Evil McNeilly, 24, was jailed for life in 1993 for leading a gang which tortured and burnt to death an innocent teenager. Suzanne Capper, 16, was held hostage in a Manchester flat where she was stripped naked, plunged into a bath of disinfectant and forced to listen to recordings of McNeilly chanting “I’m Chucky, wanna play”. Chucky is the demonic child doll in the horror film trilogy Child’s Play, which also featured in the Jamie Bulger murdercase.

Martin’s illicit affair with McNeilly started in Durham Prison’s gym, where the inmate worked out.

Martin, head of physical training at the jail, had access to McNeilly’s cell – next to Rose West’s on the wing reserved for Britain’s most notorious female killers. He also saw her in his office.

But the burly officer’s indiscretion was only uncovered two months after he had been promoted and transferred to Castington Young Offenders Institution in nearby Morpeth.

From there he sent a series of steamy letters to McNeilly which were found during Durham security checks.

A prison insider said: “All the women on H-wing, including Rose and Myra, knew what had been going on. Everyone was amazed he had got away with it for so long.”

Mother-of-three McNeilly was immediately transferred to New Hall jail in West Yorkshire. On the same day Martin was confronted. He faced suspension and a serious disciplinary investigation and chose to resign.

Martin is no stranger to entanglements with brutal women murderers.

Last December he was best man at the Durham Prison wedding of Black Widow Linda Calvey and convicted rapist Danny Reece.

Linda shot her lover Ron Cook in the head and claims to be the inspiration behind the Lynda La Plante TV series Widows.

But Martin’s own object of desire is far more evil.

At McNeilly’s trial, the court heard how her victim was beaten, shackled to a bedframe, tortured with cigarette ends, injected with drugs and had her front teeth pulled out with pliers.

The girl was then dumped in a deserted wood, doused in petrol and set alight. She survived for four days.

McNeilly was said to have been obsessed with the occult.  Comment:  May as well state that she was into Satanism and probably tortured the teen to death for favors from the Devil.
