British mother vanishes "into thin air" after dropping two daughters off at school

Specialist divers on Monday were scouring a river bed for traces of a missing woman, more than a week after she appeared to "vanish into thin air" leaving her phone still dialed into a work conference call at an isolated rural spot in northern England, police said.

Family and friends of Nicola Bulley, 45, have questioned the police theory that she fell into the river in a tragic accident. They say there is no evidence for the hypothesis which leaves them in a distressing limbo.

The mortgage adviser was last seen 10 days ago walking her dog along the riverbank after dropping her two young daughters off at school as usual in the northwestern cvillage of St Michael's on Wyre.
