DETECTIVES investigating the murder of Jo Yeates remain tight-lipped on new evidence thought to have come to light.

It’s been reported that an item which is ‘highly significant’ to the investigation has been handed in to police as they continue to hunt the killer of the 25- year-old, who was from Hampshire.

DNA analysis and other tests are expected to be carried out on the item, which is understood not to be the sock that was missing from Jo’s body when it was discovered on Christmas Day.

A spokesperson for Avon and Somerset Police said: “We’re following up many, many lines of inquiry and we cannot go into detail about individual pieces of evidence.”

Jo’s mother, Theresa Yeates, 58, from Ampfield, has also offered to take part in a TV reconstruction of her daughter’s last movements.

Officers are planning to film the final steps of the landscape architect for the BBC’s Crimewatch programme later this month.

Her father David, 63, says his wife is keen to take on the role because she has a similar height and build to her daughter.

Jo, who went to S h e r b o r n e House School in Chandler’s Ford and Embley Park in Romsey, d i s a p p e a r e d after having C h r i s t m a s drinks at The Ram pub in Park Street, Bristol, with work colleagues.

After leaving at 8pm, she was spotted on CCTV in a Waitrose supermarket , Bargain Booze off licence and at a Tesco Express in Clifton village where she bought a pizza.

Jo’s strangled body was found by a couple walking their dogs on Christmas morning in a country lane in Failand, North Somerset – just three miles from her home.
