19 March, 06:10 - Man and woman seen arguing outside University of York
Another significant line of enquiry from 2009 was the sighting of a man and woman seemingly involved in an argument on University Road, outside the University of York, at about 6.10am on Thursday 19 March – around the time Claudia was due start her shift as a chef at the university.
A member of the public said they were standing next to an unknown parked vehicle. The passenger-side door was open.
Det Sup Malyn said: “This remains a significant line of enquiry which we are determined to resolve.
“The fact that the apparent verbal altercation between the man and woman occurred outside the University of York at a time when Claudia would have been arriving at work on Thursday 19th March 2009, is obviously a cause for concern and suspicion.
“If this man and woman are entirely unconnected to the disappearance of Claudia Lawrence but have decided not to come forward previously for whatever reason, then I strongly urge them to contact the investigation team so we can rule out this line of enquiry.”
