A retired detective claims police are right to focus on the theory that missing mum Nicola Bulley fell in the river based on three key factors.
The mum-of-two disappeared on January 27 while walking her dog along the River Weir in of small village of St Michaels on Wyre in Lancashire. Police launched a huge search operation, with specialist diving teams, search dogs, drones and boats all brought in to help find the 45-year-old mortgage adviser.
Earlier this week, the search extended to Morecambe Bay, with officers seen on a board searching under Shard Bridge - seven miles from Nicola's last known location. Police have said their "main working hypothesis" is that she fell in a river, but insist they are keeping an open mind, the Mirror reports.
