Detectives hunting the killer of pregnant woman Rae Portman have come up with several possible scenarios for what could have led to her murder.
The investigation into Ms Portman's disappearance has been upgraded to a homicide because police believe the 33-year-old is dead.
"Her bank account has not been touched, there's just been no contact and no other likely possibility [than] she has been murdered," inquiry head Detective Inspector Mark Gutry said.
Police held grave fears for her safety from the time she was reported missing - by her mother Rebecca Norton on July 2 - and say information they have obtained from the public has confirmed their fears.
Ms Portman, who is known by her nickname Bok, was involved in the drug world and four associates have been arrested by police, who uncovered alleged offending while they searched for her.
