PETER Lawrence has asked people to remember his daughter Claudia and her family and friends as he marks the seventh anniversary of her disappearance today.

Claudia Lawrence was last seen walking home from the University of York, where she worked as a chef on the evening on March 18, 2009.

Martin Dales, Peter Lawrence’s friend and spokesman, said her father was having a “quiet day reflecting on seven years without his beloved daughter” and asks people to remember Claudia, her family and her friends today.

He said: “He is very thankful to the many people who have sent good wishes as it helps him feel supported as he seeks answers as to Claudia’s whereabouts. Somewhere, but where – someone knows.”

Last week the Crown Prosecution Service announced none of the four men arrested in connection with her disappearance would face charges.

North Yorkshire Police’s Detective Superintendent, Dai Malyn, who led the investigation, said it had ultimately been compromised by the refusal of some people to co-operate with their enquiries.

Last week he said: “I am left with the inescapable conclusion that this case could still be solved if only people were honest with us. The fact that they are not is agonising for Claudia’s family and they should be ashamed of themselves.”
