The family of missing mother-of-three Allison Baden-Clay faces a restless night as it waits for police to identify a body found on a Brisbane creek bank.
A person canoeing on Kholo Creek in Brisbane's west tipped off police after coming across the body of the woman on the bank at about 11am yesterday, Detective Superintendent Mark Ainsworth said.
Superintendent Ainsworth said police were yet to confirm whether the body was that of Ms Baden-Clay.
The 43-year-old's husband Gerard reported her missing from their Brookfield home, near where the body was found, on April 20.
''We are treating it very seriously that it may be her,'' Superintendent Ainsworth said at the search coordination centre set up at Brookfield Showgrounds.
''We've got to go through the normal procedures. Hopefully we'll make a confirmation either later today or tomorrow.''
The clothing found on the body was similar to Ms Baden-Clay's, he said.
Superintendent Ainsworth said her disappearance was now being treated as a homicide and police would continue searching the area.
He said Ms Baden-Clay's family had been notified the body had been found.
Her parents, Geoff and Priscilla Dickie, were coming to terms with the news, he said.
''They've been here … at the Brookfield Showgrounds being ever hopeful that there will be a positive resolution, the same as ourselves,'' he said.
''They're devastated - I can't explain it any other way.''
Superintendent Ainsworth said he could not comment on whether Mr Baden-Clay was a suspect, and said ''numerous'' people of interest had been interviewed.
News of the discovery was met with shock in the Brookfield community yesterday.
''If it is her [body that's been found], then it's obviously terrible news,'' one mother said as she picked up her children from school.
''She is well known and liked around Brookfield.
''I think everyone has been praying that she is all right.''
Water police, scientific officers and homicide detectives were investigating the scene yesterday afternoon, Superintendent Ainsworth said.
He said the Brookfield search coordination centre and the major incident control room in Indooroopilly would remain open.
Mount Crosby Road, where police have set up a command post, was expected to be open again last night after police closed it yesterday during the investigation. AAP
