Woman quit job before disappearing

As searchers plan to return to the Port Hills tomorrow in the hunt for missing Christchurch woman Emma Campbell, it has been revealed she quit her job two days before her disappearance on May 1.

Nurse Maude spokeswoman Sue Bramwell said Ms Campbell, who had worked for the organisation for three years providing home-care for the disabled and elderly, resigned on April 29.

"Staff did query it, and said we need to go through a formal process," she told The Press.

Detective Senior Sergeant John Rae said he was not reading too much into Ms Campbell's resignation but it was "another factor" in her disappearance.

"I think it was a bit sudden but what it means, we don't know," he said.

"If she was preparing to disappear, I think she would have made a lot more arrangements."

Ms Campbell's car was found slightly damaged just off Dyers Pass Rd, on May 1.

Her wallet was in the car, and her shoes were on a nearby rough path, but extensive ground and air searches of the area have failed to find her.

She was last seen on a Riccarton petrol station's security camera about 5.30am that morning.

Foul play still had not been discounted but police believed the more likely scenario was that Ms Campbell had crashed and gone into the bush either in panic or suffering a head injury.

Police, along with Land Search and Rescue volunteers, would search a wide area around the crash site tomorrow, Mr Rae said.
