Police are investigating the death of a baby found in a washing machine at a house on Brisbane's north in January.
The newborn girl was found, wrapped in clothing, at a Bald Hills home on Australia Day.
Detective Senior Sergeant Todd Reid says investigators had to wait for forensic testing before releasing more details.
"Detectives from the North Brisbane Child Protection and Investigation unit were called to an address at Bald Hills - an infant child was located deceased in a domestic washing machine at an address and since that time detectives have been investigating that matter," he said.
Police stepped up their investigation this week after the tests showed the baby had not been stillborn.
Detective Senior Sergeant Reid says it has been a complex investigation.
"As a result of some recent forensic testing and some results that have been achieved - we have been treating it as suspicious the entire time - but we are now able to confirm it is suspicious and we are urging any members of the public who may have information about that matter to contact Crime Stoppers," he said.
Senior Sergeant Reid says police are particularly interested to hear from anyone who knew of the woman's pregnancy. Read More
