A private search expert has said if his team cannot locate Nicola Bulley in the river then she is not there and he would not rule out "third-party involvement" in her disappearance.
Ms Bulley, 45, went missing on January 27 in St Michael's on Wyre, Lancashire. Police think mortgage adviser Ms Bulley, after dropping her daughters off at school, tragically fell into the water while walking her dog along the River Wyre.
However, Peter Faulding, leader of underwater search experts Specialist Group International (SGI), said he is "very surprised" that she has not been found in river searches. Mr Faulding has been searching the river for three days after being called in by the family to help.
