The last time the 35 year old York chef was seen alive was on March 18th 2009 when she was dropped off at her home in Heworth by a work colleague in the middle of the afternoon.

We know Claudia was safe up until that evening when she spoke to her mum Joan on the phone, but after 8.30pm her whereabouts have been unaccounted for.
