The family of murdered Joanna Yates pay tribute

The family of murdered landscape architect, Joanna Yeates, have released a statement paying tribute to the 25 year old.

Speaking via police they said she was 'a beautiful and talented person who was destined to fly high.'

They also say she was 'stolen' from them and that their lives had stopped as soon as they knew she was missing.

Jo's boyfriend Greg Reardon, who reported her missing on 17 December said in a statement that Jo was 'a beautiful woman in mind, body and soul.'

Miss Yeates was found strangled on Christmas Day, a few miles from her home in Bristol.

Police have been granted more time to question her landlord Chris Jefferies about her death.

Jefferies, 65, was arrested on Thursday morning and a magistrate granted Avon and Somerset Police an extension to hold him in custody.

The development came after officers spent the day talking to Peter Stanley, 56, a neighbour of the retired public school teacher in Clifton, Bristol, who said he and Mr Jefferies helped start Miss Yeates's boyfriend's car the day she vanished.

Mr Stanley recalled how they used jump leads to start Greg Reardon's car, sending him on his way to Sheffield.

"It was a non-event at the time, but absolutely poignant now - what if we didn't get the car to start?" said Mr Stanley.

Hours after successfully starting the car, Miss Yeates, a landscape architect, disappeared and her snow-covered body was discovered more than a week later on Christmas Day.

Police confirmed Mr Stanley, who lives in a flat in the mansion to the right of Mr Jefferies' in Canynge Road, Clifton, is being treated as a witness.

The 56-year-old has been helping detectives with their inquiries and was spotted on Friday showing the police a distinctive army-style 4x4 truck in the driveway.

Mr Jefferies, who sports distinctive straggly white hair and was described by a neighbour as a "nutty professor type", was arrested at 7am on Thursday.

The bachelor was taken into custody just 24 hours after he claimed he saw three people leaving Miss Yeates's flat on the night she vanished - December 17.

The suspect is a prominent figure in his Neighbourhood Watch group and taught English at Clifton College, just yards from his flat, from the early 1970s. He took early retirement in 2001.

He is an enthusiastic activist for the Liberal Democrats in Clifton and a member of the Clifton and Hotwells Improvement Society (CHIS), which campaigns to conserve buildings in the area.

CHIS secretary Rosemary Musgrave said: "He's certainly an active member and does come to meetings from time to time. He's not a member of the committee, though."

In 2005 he was at the forefront of efforts to stop building work on fields near his home.

He led the Canynge Road Campaign Group to save the fields from development and wrote a series of letters to Bristol City Council outlining the group's opposition to the scheme.
