The chief executive of a specialist dive team assisting in the search for Nicola Bulley said he is "very surprised" that she has not been found in river searches.
Mum-of-two Nicola vanished while walking her dog near the River Wyre in Lancashire on Friday, January 27, and has not been seen since. Family and friends brought in a private dive team to search the river.
Peter Faulding of Specialist Group International told Radio 4's Today programme: "The initial area where Nicola went in, where the bench is, the police thoroughly searched that the same day, and did it again days later. From all my experience, I would expect a body when it goes down and drowns, to go straight down to the bottom, and remain there until the body starts to decompose and then it will start moving."
He added that there is not enough of a current in the River Wyre, where police believe Ms Bulley may have fallen, for her to have been moved downstream on the day she went missing. Mr Faulding said of continued search efforts "today we're going to concentrate again upstream in the non-tidal section of the river, including past the bench again, just in case".
