Criminologist and child protection expert Mark Williams-Thomas told Daybreak: “They were living with him and did not know. They really were living with a monster.
"And for anyone outside who says ‘why did you not know? Why did you not see what was going on?’ I can completely understand. I’ve spent a lot of time with the family, I’ve spoken to the people who knew him and I tell you what he was a normal person.”
The mother of murdered Tia Sharp has told Daybreak that if she saw her daughter's killer again she would ask him "why?"
Speaking to Daybreak, Natalie Sharp said when she knew Stuart Hazell he was "soft, gentle," and "friendly", "there weren't a bad bone in him", she added.
Stuart Hazell was sentenced to a minimum term of 38 years in prison after finally admitting the murder of schoolgirl Tia Sharp.
Ms Sharp added that she trusted Hazell with all of her children, "100% explicitly".
Admitting that she wanted to visit him in jail she said she wanted to ask him why he did it, "but then is he gonna answer the questions? Then I wanna put my hands around my throat".
Speaking to ITV's Tonight, Tia's mother, Natalie, said Stuart Hazell didn't deserve to be in jail - or to die. She said he only deserved to suffer.
Speaking to ITV's Tonight, Christine Sharp, Tia's grandmother, said she wanted to believe Tia was coming home even after police found a body.
As the Judge passed sentence at the Old Bailey, Steven Carter put his head in his hand and was comforted by his partner.
– Detective Chief Inspector Nick Scola, Senior Investigating Officer
I am very pleased at today's sentence. A minimum of 38 years is satisfying for both the investigating team and Tia's friends and family. Hazell will have a very long time in prison to think about what he has done.
As some of Tia's relatives left court, they shouted "Nowhere near long enough" and "RIP Tia". They had listened to the Judge summing up the case, in which it emerged Stuart Hazell had developed a sexual interest in Tia.
– Mr Justice Nicol
It is an aggravating feature that your victim was so young. So too is your abuse of trust. Tia's mother allowed her to come and stay with you because she trusted you to look after her.
By first sexually assaulting and then killing Tia you betrayed that trust in the most grievous way possible. And that breach of trust reverberates still.
