While the actual search of Sand Hutton Gravel appears to have been somewhat fruitless, police say that they have been contacted by members of the public in the meantime.
DSI Wayne Fox gave a little more insight into the reasons yesterday, saying that separate strands of information had been received by detectives.
He said: “When we assessed these separate and independently-sourced pieces of information against the wealth of information already generated during the last 12 years, we found they correlated with other information pointing to the area of Sand Hutton.
DCI Wayne Fox said: “As a result of the publicity surrounding the last two weeks, members of the public have come forward with new information for which I am grateful. This will be assessed and investigated in the coming days and weeks."
If you have any information that could assist the investigation, please contact North Yorkshire Police on 101, select option 1, and pass details to the Force Control Room, quoting "Claudia Lawrence".
If you would prefer to remain anonymous, please pass information to the independent charity Crimestoppers on 0800 555 111,quoting “Claudia Lawrence, North Yorkshire Police“.
