London: A pornography-obsessed 38-year-old Briton has stabbed and strangled his teenaged niece to death to fulfil his sick obsession, a media report said.
John Maden, who had downloaded a collection of sadistic `snuff` movies from the Internet, enticed his 12-year-old niece Tia Rigg to his home on the pretext of getting her to look after his daughter, Daily Mail reported on Monday.
Instead he drugged the unsuspecting youngster before torturing and abusing her, then stabbing her in the stomach and strangling her with a guitar string.
Minutes later, Maden made a chilling 999 call in which he confessed to the horrific murder, which he said he`d committed "because I felt like it".
He was ordered to serve the rest of his life behind bars for what a judge branded his "unspeakable" crime, joining the ranks of Britain`s most notorious murderers, including Ian Brady and Yorkshire Ripper Peter Sutcliffe.
Jobless Maden had become fascinated with sadistic `snuff` movies - films showing a murder being committed - while downloading a sick library of violent pornography and explicit images of children, a court heard on Monday.
Tia, the daughter of Maden`s sister, Lynne, frequently came round to his home in Cheetham Hill, Manchester, to babysit for his 10-year-old daughter, and he secretly began plotting to act out his dreadful fantasy on her.
The divorced father-of-one downloaded more than 2,000 explicit images from the Internet, including the most extreme level-five categories of child porn - police sources said he had obtained most of such photographs that are in existence.
On April 03, Maden called his sister and asked if Tia could come round to babysit, before drugging the youngster with tablets he had been given to combat his psychotic episodes.
Just 45 minutes after she arrived, Maden dialled 999 and made a `chillingly calm` call to report what he had done.
Police officers found Tia`s naked body with her hands tied behind her back and surrounded by two knives and a sex toy.
She had been tortured and raped before being stabbed in the stomach and finally strangled with a guitar string.
After his arrest, Maden claimed he had been listening to a "bad voice" in his head "controlling him and telling him what to do".
At Manchester Crown Court he admitted rape, torture and murder and was jailed for life.
"When this nightmare happened, it killed me inside," her mother said. "My heart has been broken and will never mend. All that is left is a big empty hole.
"Tia was my whole world. I miss her big smile every morning and her beautiful freckly face."
