KEY POINTS:
It has been 12 days since Christchurch woman Emma Agnew disappeared and police say her family are starting to consider the possibility of foul play.
Ms Agnew, a profoundly deaf 20-year-old, has been missing since November 15. Police say they have "grave concerns" for her safety.
Detective Inspector Tom Fitzgerald said divers yesterday completed their search of about 8km from the lower Styx River through to Spencerville without success, One News reported last night.
Ground searches in the Spencer Park and Brooklands area, north of the city, and searches at North Canterbury's Kate Valley landfill site have also been fruitless.
"The family start to realise that the possibility of foul play is there. It's traumatic for them," Mr Fitzgerald said.
"We all get to go home to our families - whether it's for four hours or three hours it doesn't matter. Emma's family don't have that and that's what drives us."
The last contact from Ms Agnew was in a text to her family just after 10.30am on November 15, when she said she was planning to meet a man interested in buying her car.
Her partially burned red Mazda Familia was found in Bromley Park, eastern Christchurch, that night.
Police are still awaiting the forensic results from the car.
