Claudia Lawrence investigation 'haunts' top detective
The detective leading the hunt for the killer of Claudia Lawrence, who disappeared exactly two years ago, has said he is haunted by the case.
Miss Lawrence, who worked as a chef at the University of York, was last seen in York on 18 March 2009.
Det Supt Ray Galloway said: "It does haunt me to the extent that we've not been able to conclude the investigation by finding Claudia or her killer."
He also said police may have spoken to her killer during the investigation.
"There is every potential that we have [spoken to her killer]. I don't know that we have, but there is every potential we have."
Claudia's father, Peter, said he was "amazed" by the comments from the police.
"They have no more idea than I do about what has happened to Claudia," he said.

We are tenacious and determined and we won't rest until every line of inquiry is pursued”
The inquiry is the largest in the recent history of North Yorkshire Police, but despite the high-profile nature of the investigation her disappearance remains unsolved.
However, Mr Galloway told the BBC he remained determined to solve the case.
"I do have restless nights and I have thoughts about this investigation every day on a professional and a personal basis," he said.
"It means everything to me.
"We are tenacious and determined and we won't rest until every line of inquiry is pursued."Family's hopes
Mr Galloway appealed again for anyone who knew what had happened to Miss Lawrence to come forward.
"Nothing could be simpler than to put an end to all this pain for the Lawrence family and the pressure and guilt that you must be feeling.
"Just make that call. That's all it would take."
Miss Lawrence's family and friends continue to hope that she is alive.
Her father said: "I've always believed I would have felt something the moment anything happened to her.
"I will continue to believe that until we found out differently."
Miss Lawrence, who was 35 when she disappeared, was first reported missing after failing to turn up for her early-morning shift at the University of York on 19 March 2009.
Many appeals for information have been made by her family and the hunt for her has taken detectives to Cyprus and the Republic of Ireland.
During the inquiry hundreds of properties have been searched, including Miss Lawrence's local pub, just a few doors from her home in Heworth Road, York.
A £10,000 reward for information about the case, from Crimestoppers, was withdrawn earlier this month. The charity said it had given the case "unprecedented" support and needed to help others.
The police investigation has been scaled back and no officers now work full-time on the investigation.
