Detectives are now investigating the role that drugs could have played in the deaths of eight children in Cairns on Friday.
The mother of seven of the eight children who were killed, Mersane Warria, 37, remains under police guard in Cairns Hospital and has been formally interviewed.
Detectives investigating the deaths are considering the possibility that she was on the drug ice at the time of the deaths.
"These are all things that will be presented to a court," Detective Inspector Bruno Asnicar said.
"As you can imagine, all of these things are extremely relevant and I understand that people are very interested in those facts."
In another development overnight, it emerged not all the children had been stabbed to death.
Detective Inspector Asnicar said post mortems will reveal the causes of death, which could include suffocation.
The post mortems are expected to be completed by Sunday afternoon with charges possibly laid shortly after the forensic investigation.
