Ex-detective links double killer Halliwell to murder of Claudia Lawrence
The disappearance of chef Claudia Lawrence fits double murderer Christopher Halliwell's "pattern of behaviour", the senior detective who brought him to justice has said.
Former detective superintendent Steve Fulcher caught the 52-year-old following the abduction of Sian O'Callaghan from outside a nightclub in Swindon in March 2011.
The taxi driver would go on to confess to murdering both Miss O'Callaghan and another woman, Becky Godden, and now Mr Fulcher believes Halliwell's links to the area where Miss Lawrence vanished should be investigated.
Miss Lawrence was last seen on March 18 2009 and was reported missing the following day after she failed to turn up for a shift at work at the University of York.
Police have said they believe the 35-year-old was murdered, although no body has ever been discovered.
Mr Fulcher told the Sunday Express: " Claudia Lawrence disappeared from York seven years ago. Halliwell's father lived a few streets away from where Claudia went missing.
"It fits his pattern of behaviour - abducting women walking alone either late at night or early in the morning."
The detective, who is now a security consultant in Somalia, also linked Halliwell to other unsolved crimes, including the murder of Melanie Hall.
The 25-year-old university graduate disappeared in 1996 after leaving a nightclub in Bath, Somerset and h er remains were later found in vegetation off the northbound slipway at junction 14 of the M5 at Thornbury in 2009.
Mr Fulcher said: "The circumstances match his modus operandi in abducting a girl, late at night, from a nightclub. Evidence of her being tied up with rope is consistent with Halliwell's interests."
Halliwell was already serving a life sentence for the murder of Miss O'Callaghan, 22, when he was last week convicted and sentenced to a whole life term for the killing of Miss Godden, 20, in 2003.
The father-of-three, formerly of Nythe, in Swindon, originally confessed the crime to Mr Fulcher after leading the detective to the field where he had dumped the body of Miss O'Callaghan.
But the confessions were later ruled inadmissible by a High Court judge because Mr Fulcher failed to caution the killer, breaching police procedural rules for the interviewing of suspects.
The detective was later found guilty of gross misconduct by a police disciplinary panel but kept his job after receiving a final written warning. He resigned from Wiltshire Police several months later, ending his 27-year police career.
But the father-of-two won praise from Miss Godden's mother Karen Edwards, who said the her daughter's remains may never have been found if it was not for the his actions.
He has criticised police forces for "obsessing" about procedure rather than looking at the bigger picture and said he wants to ensure detectives in a similar position are not treated in the same way.
Mrs Edwards also said she believed her daughter's killer could be linked to Miss Lawrence's disappearance as well as that of Miss Hall.
She told the Mail on Sunday her own inquiries into Halliwell's background found that the date when Miss Lawrence went missing, exactly two years before he abducted Miss O'Callaghan, could be significant.
"I believe he has been up and down the country murdering young women," Mrs Edwards said.
"He used to be a groundworker up north - I know somebody who worked with him on the same building site. He would go and have a pint with the lads and then disappear.
"Serial killers are usually triggered by dates. That was the day that Halliwell broke up with one of his partners.
"Halliwell was familiar with York - his father lived in Huddersfield - and the description of Claudia's murderer is identical to him - a left-handed smoker, 5ft 8-10in, with slightly receding hair and a skinny build."
Martin Dales, friend and spokesman of Miss Lawrence's father Peter, said the claim should be investigated.
He said: "I think the retired officer in question has a detailed knowledge of things. The overriding point is really whoever has done whatever to Claudia, it has been an incredibly long time.
"It's a heartbreaking period to go without somebody and we hope this will come to some conclusion - whether this is it is for other people to find out.
"There are pluses and minuses of thinking: 'Are we going to get some sort of conclusion or is this just another false dawn?' All the time, Claudia is still not here.
"It's got to be thoroughly checked out."
