DETECTIVES are scouring the underground drains of an upmarket Cairns suburb to piece together the fate of murder victim Li Ping Cao.
Klaus Andreas, 68, of Brinsmead appeared gaunt and stoney-faced as he faced Cairns Magistrates Court today charged with the murder of his Chinese-born wife of five years.
His dramatic arrest, with more charges likely, comes six days after the accused killer made an emotional public appeal for help in a missing persons search when his wife vanished without a trace on October 31.
Forensic and scientific squad officers from Brisbane and Cairns cordoned off the Chapel Close murder scene and ordered council workers to dig up sections of underground drainage pipes as they hunt for clues.
Regional crime co-ordinator Detective Inspector Bruno Asnicar said he would not discuss any “gruesome details”.
“We are satisfied the victim is deceased, I’ll leave it at that,” he said.
“The house is the focus of our investigation and will be until the weekend.”
Detective Inspector Asnicar said the motive for murder was still under investigation by officers in a major incident crime room including Brisbane Homicide squad detectives at Cairns Police Headquarters.
“This investigation is far from over.
“It is very much an intense scientific and forensic effort.
“We’ve got a lot of gaps in the timeline as to what happened between October 31 and now, so we are appealing for public help on that.”
Neighbours on Tuesday told The Courier-Mail the family kept to themselves but had been heard arguing prior to the disappearance.
One, who did not wish to be named, said a possible source of tension may have been the repatriation of the teenage son of Ms Li, 42, who had been living with the couple, back to China.
Det Insp Asnicar said he could not comment about the “demeanour or attitude” of the accused who had been assisting police since the disappearance.
It is understood the pair met in China but it is unclear if they met through an online relationship website.
Family are due to fly out from China to collect Ms Li’s remains for burial in coming days with the assistance of the Chinese consulate in Canberra.
Defence lawyer Stephen O’Reilly today told the court it was likely more charges would be laid against his client in coming weeks.
Mr Andreas was remanded in custody to reappear on November 29.
