At 2:17pm on 3 April 2010, Maden, who had an "obsessive interest" in pornography relating to paedophilia, rape and torture, telephoned Rigg's mother and asked for Tia to go to his home in Dalmain Close, Cheetham Hill, in order to babysit his 12-year-old daughter. When she arrived at 3:00pm he drugged her with Olanzapine, an antipsychotictranquilizer that he had been prescribed. He then inflicted a "horrific catalogue of sexual injuries" on her before stabbing her and strangling her with a ligature made from a guitar string. At 3:45pm, Maden telephoned the 999emergency services number and said: "Hi, I would like to report a murder." He then gave his name and address and when asked by the operator what had happened he replied: "My niece has been murdered by me ... I have just finished killing her now." Asked why he had killed her he answered: "Because I felt like it" and terminated the call. Police officers from Greater Manchester Police arrived at the address two minutes later. Maden opened the door to the officers, who described him as "chillingly calm", and directed them upstairs. They found Rigg's body face-up on the floor of a spare bedroom, naked except for her socks, with the ligature still fastened around her neck and her hands tied behind her back with shoelaces. Next to the body were two knives, a broom handle and a sex toy, all of which were stained with blood. A post-mortem found that Rigg had suffered severe blood loss from her stab wounds and internal injuries, but the primary cause of death was ligature strangulation.
Aftermath
Maden was tried at Manchester Crown Court on 4 October 2010. Prosecutor Gordon Cole QC told the court: "In the year or so prior to April this year, the defendant had developed what can properly be described as an obsessive interest in images and literature relating to paedophilia, rape and torture. He had an extensive library of such materials which included literature dealing with methods of killing." Police had found "hundreds of extreme images of child abuse and violent pornography" on Maden's laptop, plus more material on his mobile phone in folders named "snuff", "snuff stories" and "brutal rape". Detective Chief Inspector David Warren, who led the investigation, revealed that Maden refused to explain his actions and had never shown remorse for the killing. After pleading guilty to rape and murder, Maden was sentenced to life imprisonment with a recommendation that he should never be released. Passing sentence, Mr Justice Keith told him: "It is inescapable that Tia Rigg died because you decided to realise your fantasies about torturing and killing a young child. It is difficult to know how long Tia's ordeal lasted. The terror, the unimaginable pain you inflicted on her, the indignities you subjected her to while still alive. It was planned, it was premeditated and her agony must have been prolonged. This is one of those exceptional cases in which the only just punishment requires you to be imprisoned for the rest of your life." A report issued regarding the case found problems with how social workers had handled Tia's care.
