Stuart Hazell Stuart Hazell A paedophile who assaulted and murdered his step-granddaughter then hid her body from police was caught by experts studying videos of him – and the fact his biology gave away his lies.

While many people may think lying comes naturally to them, and make efforts to control their body language in an attempt to get away with it, investigators looking into the disappearance of 12-year-old Tia Sharp were able to catch her killer by looking at his ears.

In an episode of Faking It: Tears Of A Crime scheduled to air tonight, experts reveal how they found out Stuart Hazell had assaulted Tia, murdered her, then hid her remains in his loft after taking pictures of her body.

"At this point you'll see in the video the tone of his ears change, giving us a clue that his blood pressure is increasing.

"In the ears and the nostrils we have some very fine capillaries and when the blood pressure increases, that's the first place that you may feel it," case investigator Cliff Lansley tells the programme.

"You see them start to turn red, it gives us a clue that this person may be experiencing fear. And that could be fear of being caught in a lie."

He had been at the centre of police suspicion ever since Tia was first reported missing from New Addington estate in Croydon in August 2012, with Hazell claiming to have been the last to see her.

But when rumours started swirling, Hazell – who at the time was with Tia's grandmother Christine Bicknell for over five years (he'd previously had a short relationship with Tia's mum, Natalie Sharp) – went on TV to read out an appeal for Tia's safe return, in an attempt to portray himself as a grieving relative.

But police made the grim discovery of her badly decomposed body hidden in the attic of her grandmother's home a week later.

The house where Tia was murdered has since been demolished.
