On December 7th, 1992, Suzanne was lured to Jean Powell’s home, where Glyn and Dudson were already waiting.

She was grabbed as soon as she arrived and held down while Glyn shaved her head and her eyebrows and then made her clean up the hair and place it in a bin.

Then he placed a plastic bag over her head and walked around her while hitting her on the head.

She was then kicked by Jean and Bernie as she lay curled up on the floor and both women took turns beating her with a three-foot-long wooden instrument and a belt.

She was then taken to the bathroom and forced to shave off her own pubic hair as “ritual humiliation in revenge for having caused, as they claimed, Dudson and Bernie themselves to be shaved.”

Afterwards, Jean locked her in a cupboard overnight.

The following morning, Suzanne was taken upstairs and locked in another cupboard.

On December 8th, she was transferred to Bernie’s house because of concern that Jean and Bernie’s six children were disturbed by Suzanne’s crying.

There she was tied spreadeagle to an upturned bed with electrical flex in a downstairs back room.

Over the next five days, Suzanne was subjected to a series of violent acts, “increasing in severity and brutality as the time passed.

She was regularly beaten and injected with amphetamines, burned with cigarettes, and had rave music — in particular “Hi, I’m Chucky (Wanna Play?)” by 150 Volts, featuring samples from the movie Child’s Play — played at maximum volume through headphones.

Bernie would commence each torture session with the phrase “Chucky’s coming to play.”

At some point during the week, Pook and Leigh called at the house and saw Suzanne, blindfolded and gagged, tied to the bed.

By this time, Suzanne had been lying in her own urine and feces for several days and was placed in a bath containing concentrated disinfectant and scrubbed with a stiff brush with sufficient force to remove skin.

Pook then used pliers to extract two of her teeth, which police later found at his house “like some kind of macabre trophy.”

Dudson said: “I was stood at the doorway with Jeanie [Powell] and Bernie [McNeilly].

Cliff [Pook] took her gag off.

He told her to open her mouth.

He said: ‘Right, I’m going to rip your teeth out’. He started hitting her teeth with the pliers. He got the pliers on and started pulling it out. But it just snapped and chipped. Then he hit them a few more times. He put the pliers on again and really, really pulled. He pulled Suzanne’s head forward until there was a snap and he had the tooth in the pliers. He did the same again and he was laughing.”

In the early hours of December 14th, 1992, Suzanne was forced into the boot of a stolen white Fiat Panda car and driven 15 miles (25 km) to a narrow lane at Werneth Low, near Romiley, on the outskirts of Stockport.

In the car were Bernie, the Powells and Dudson.

Bernie “giggled” as they made the journey.

Jean later said that Suzanne was pushed down an embankment, into a patch of brambles, where Bernie poured petrol over her.

When Bernie had difficulty getting the petrol to ignite, Glyn Powell and Dudson made multiple attempts before lighting the girl’s body on fire.

Bernie began to sing “Burn baby burn! Burn baby burn!” from The Trammps song, Disco Inferno.

After her attackers left, Suzanne managed to scramble back up the embankment and stagger along the lane for approximately a quarter of a mile (400 metres) to Compstall Road, despite extensive burns.

She was found at 06:10 by Barry Sutcliffe and two of his colleagues on their way to work.

They immediately took her to a nearby house and roused the residents, Michael and Margaret Coop, to call for an ambulance.

Michael Coop said: “Both her hands appeared like ash. Her legs were just like raw meat and her feet appeared to be badly charred. I was struck by how polite the victim was. She was constantly thanking my wife for her assistance.”

Margaret Coop said: “I instinctively went to put my arms around her but she pulled away because she could not bear to be touched. Her head was shaved and there were recent, not new, cuts to her head. Her face was almost featureless. Her hands were red raw and black at the fingertips. Her legs were red from top to bottom. She couldn’t bear anything near her legs.”

Suzanne drank six glasses of water, but was unable to hold the glass herself because of the injuries to her hands.

Suzanne was rushed to the hospital and was able to give the names of her six assailants, as well as Powells’ address, before falling into a coma.

The extent of her burns was such that her mother and stepfather were unable to recognise her, and she was positively identified by a partial fingerprint from her thumb, the only part of her hands not severely burned.

She died on December 18th, 1992, without regaining consciousness.
