Crimewatch is 25 this month! Here is a summary of tonight's special show:

A reconstruction of the last known movements of 35-year-old chef Claudia Lawrence, who went missing in York on March 18. Plus, to celebrate the 25th anniversary of the programme, viewers, victims and detectives who have been involved in some of the show's highest-profile incidents return to tell their stories, and Kirsty Young, Rav Wilding and Matthew Amroliwala chart how the series has evolved.
