Inside bag spook's apartment - The Sun

His emotional mother, Ellen, walked out of the inquest into her son's death as police footage of his home was shown publicly for the first time.

It also emerged that traces of DNA belonging to a SECOND person were found on the sports holdall containing the MI6 codebreaker's body.

The video took the inquest on a "walking tour" through the home and showed an orange wig with blonde tints hanging from a living room chair, and make-up on a nearby sofa.

Inside the spare bedroom was an estimated £20,000 worth of women's clothing — all "in pristine condition" — and other wigs.

There were also 26 pairs of mainly designer shoes, including Christian Louboutin, Chloe, Stella McCartney and Christian Dior labels in the size of Mr Williams. One pair alone was worth £1,000. Four pairs had been used.

Neatly-folded piles of trousers were seen on the maths genius's bed in the top-floor apartment in Pimlico, Central London.

Footage then showed close-ups of the white bathroom suite where his body was discovered.

The camera zoomed in on the red North Face bag showing bulges from athletically-built Mr Williams' limbs inside and a brass padlock locking two zips together from the outside.

Detective Chief Inspector Jackie Sebire said the second person's DNA was found on the zip toggle and padlock.

She said the riddle of how Mr Williams came to be in the bag was "at the heart" of the police investigation.

She told the inquest: "I've always been open-minded but it's my opinion from early on that a third party was involved in the padlock being locked and Gareth being placed in the bath." Westminster Coroner's Court was also shown a police laser-generated 3D image of the holdall. It showed Mr Williams naked with the padlock keys under him.

DCI Sebire said: "He was in the foetal position. In my opinion he was very calm. His face was very calm. His hands were resting on his chest."

She said Mr Williams had not damaged the bag, adding: "He was very muscular, he trained regularly. It is only my opinion but I would at least expect some tearing to the netting."

GCHQ worker Mr Williams, 31, of Anglesey, North Wales, was found dead on August 23, 2010.

There was no sign of a break-in or any struggle in his "incredibly tidy" home.

He was 12 months into a three-year posting to MI6 when he died. His closest pal Sian Lloyd-Jones said Mr Williams was unhappy at work. She did not think he was a transvestite — but could not explain the women's shoes in his size. The inquest continues.
