The disappearance of Claudia Lawrence has been one of the most high-profile and perplexing missing person cases of recent years.
Miss Lawrence, who worked in a kitchen at York University, was last seen at about 3pm on March 18, 2009, as she made her way home from her shift and reported missing by her father two days later.
Police released a timeline of the last night the 35-year-old was seen alive:
18 March, 14:31 - Claudia leaves work
18 March, 14:35 - 14:36 - Claudia walks through university campus
18 March, 14:47 - Claudia walks home and appears to post something
18 March, 19:27 - 21:12 Claudia uses her telephone
18 March, 21:01 - White Vauxhall Astra Van parked near Claudia’s home
19 March, 05:35 - Left handed smoker - seen with a woman on Melrosegate bridge
19 March, 05:42 - Old-style light coloured Ford Focus seen braking outside Claudia’s home
19 March, 06:00 - Claudia fails to turn up for work
19 March, 06:10 - Man and woman seen arguing outside University of York

19 March, 12:10 - Claudia’s mobile phone is switched off.
20 March, 14:07 - Claudia is reported missing by her father, Peter Lawrence
Despite this, and a Crimewatch recreation, there was no breakthrough in the case until North Yorkshire Police launched a review in 2013 after a new major crime unit was established.
A 60-year-old man was arrested on suspicion of murder but was later released without charge.
Her father Peter has maintained throughout that someone knows what happened to his daughter and had been given renewed hope with recent developments.
