Premise: Concerns have been raised that potential leads in the hunt for missing York woman Claudia Lawrence are not being followed up quickly enough. It comes after hotel staff in Malton contacted police after a stranger in the bar expressed satisfaction when asked if the chef was still missing. The incident happened more than three weeks ago and staff said detectives had not yet been in touch. Police said leads were being assessed in a methodical and structured way.
Hypothesis: Claudia Lawrence has black hair.
