Father's hope over Claudia Lawrence film
The father of missing York woman Claudia Lawrence has said he hopes a documentary about her disappearance will prompt new hope in the inquiry.
The film, Missing - The Claudia Lawrence story, follows family and friends in the 16 months since the York university chef was last seen.
Miss Lawrence, who was 35 years old when she went missing, was last seen leaving her workplace on 18 March 2009.
Mr Lawrence said: "Somebody out there does have a information about Claudia."
The Claudia Lawrence investigation is one of the largest carried out by North Yorkshire Police and has so far cost more than £600,000.
Police are treating her disappearance as suspected murder.
Mr Lawrence said watching the film, which is due to be broadcast on Channel 4 on 13 August, had been "extremely moving".
The 64-year-old: "I just hope this film pricks the conscience of someone who has information about Claudia's disappearance to pick up the phone."
