Teenager ... 2002 shot of Joanna Yeates in badminton gear
Solent Police extended their search to the rifle range belonging to Clifton College - where Mr Jefferies once taught English literature. The range is next door to Jo's home.
Avon & Somerset Police also said their detectives had been alerted to the disappearance of another young woman three days after Jo vanished.
Helen Van Duivenbode, 28, went missing from her home at Okeford Fitzpaine, near Blandford Forum, Dorset, on Monday, December 20.
The village lies around 50 miles from Bristol. Helen was last seen by her parents Bernard and Alexandra, who raised the alarm when they failed to contact her over Christmas. Dorset cops said there was "great concern" for her.

Solent Keith Pavey, her boss at architects BDP, described her as "a talented and committed professional".
A tribute was also paid by Neil Hopkins, Jo's former principal at Peter Symonds College, in Winchester, Hants.
They spoke as a new picture was released, showing a smiling Jo aged 17 with her badminton teammates and coach in 2002.
Police insisted that Clifton remained safe for women despite the killer being still at large.
Chief Superintendent Jon Stratford said: "There is at present no specific intelligence or information to suggest an increased threat to people's safety."
Comment : This tells me so much, the police may or may not have someone in mind but it is my belief all signs point to Jo having known her killer and the police are in between the lines explaining this to the public. The attack not reported as 'frenzied' nor of a sexual nature , a crime of passion then ? an act of domestic violence ?....but only time will tell. No 'Warning' of' women beware there is a killer loose on the streets', the police it seems do not believe the 'killer' will strike again.
