The mortgage adviser, 45, was last seen on January 27 walking her dog Willow near the river in St Michael's on Wyre, Lancashire.
Her disappearance sparked a massive search which saw police, firefighters, mountain rescue, underwater teams and the local community comb through a massive area from the river to the coastline.
