Mrs Bates, who has two sons, Andrew, 39, and Paul, 33, said: 'I know I shouldn’t say this, but I wish I’d killed him the first time I saw him. That way Kelly would still be alive.' Over three barbaric weeks, Smith burnt Kelly-Anne with an iron, scalded her with boiling water and even gouged out her eyes. Smith also tied her to a radiator by her hair, broke her arm and knees and stabbed her all over her body with knives, forks and scissors, causing 150 separate injuries before beating her with a shower head and drowning her in the bath. Throughout the horrific onslaught, the terrified teenager was alive, begging for mercy. Smith, who was then 49, got life imprisonment and must serve a minimum of 25 years for his horrific crimes.

She also adored children, and often babysat for neighbours. She said: 'Kelly loved children and wanted to be a teacher. She was soft-hearted and very maternal.' Sadistic killer James Smith . At 14, while babysitting for a friend, Kelly-Anne met James Smith. He began a grooming process which was so secretive that her parents knew nothing about him for two years. When Kelly-Anne was 15, she stayed out over night and her panicked parents called the police. When she finally came home, the following morning, she claimed to have stayed over with a schoolfriend called Rachel. Mrs Bates said: 'I knew she was lying. It wasn't like her, but I'd no idea what was going on. 'Kelly was a good girl. As well as babysitting, she had a job on a market stall at weekends. She played hockey and she was clever at school. She was hard-working and sensible and I could never have dreamed she was being groomed by a monster.' She said Kelly-Anne once arrived home with a black eye and told her parents she had been attacked by a gang of girls in the street. Soon afterwards, Kelly-Anne announced she had a new boyfriend, James Smith, who she said was 32 years old. 'The first time I met him, he swaggered down the stairs and it made the hairs stand up on the back of my neck,' said Mrs Bates. 'He was much older than I expected and this wasn’t the man I wanted for my daughter. I vividly recall seeing our bread knife in the kitchen and wanting to pick it up and stab him in the back. 'It was a bizarre thought - I would never normally think of anything so violent and now I wonder whether it was some sort of sixth sense. 'I’ve thought about that many times.'

She was very strong-minded and she wouldn’t listen to me. And I was worried that, if I fell out with her, it would just push them closer together. 'One night she came home and her face was black and blue. Another time, her hand was bruised. I suspected Smith was hitting her, but Kelly-Anne denied it. 'I rang the police but they said there was nothing they could do without a statement from Kelly.' In November 1995, 17-year-old Kelly-Anne moved in with Smith who lived in Gorton, Manchester.

'On one visit he showed me a hole in his floor boards where he said he'd had a gas leak. 'Just a few weeks later, he kept Kelly prisoner in the hole while he tortured her.' Mrs Bates said she then discovered that Smith was 48 years old - 21 years older than Kelly-Anne. She said she pleaded with Kelly-Anne to leave him, but by now, Smith controlled all their contact. In the weeks before her death, Kelly-Anne endured unimaginable torture while her family - terrified of pushing her even further into Smith’s clutches - waited by the phone. 'In April, I got a Mother's Day card from Kelly in Smith's handwriting and I'd had enough,' she said. 'But I was torn; I didn't want to keep going round there because I thought it was making things worse. 'It haunts me to think if we had gone round there she would be alive today.' Mrs Bates said she contacted the police domestic violence unit and was encouraged to give her daughter its leaflets.
