A friend of missing Nicola Bulley said nothing about her disappearance was "making sense", as she worried about her being gone for so long.
Mum of two Ms Bulley was last seen walking her dog 12 days ago by the river in St Michael's on Wyre in Lancashire.
Her friend Heather Gibbons said the 45-year-old's family was "appreciative of all the police have done" but no-one would know what happened "until we have some evidence".
