Police will be looking into three theories while trying to find missing Nicola Bulley, a retired detective has told the Mirror.
The mortgage adviser, 45, disappeared last Friday morning while walking her brown spaniel Willow along the River Wyre in the tight-knit village of St Michael's-on-Wyre in Lancashire.
Police have stressed that they don't think there is any third-party involvement. However, family and close friends have told the Mirror they fear someone has taken her.
