Taskforce Mallee are asking us to be patient, as over week of forensic testing has yet to determine the gender of the child found in the suitcase at Wynarka.
A DNA profile is also alluding scientists as they look into alternative forms of testing.
So far officers have fielded evidence from over 200 calls to Crime Stoppers and they've now ruled out 20 children from the investigation.
There have also been more reports from motorists who saw the man walking with a suitcase along Karoonda highway a few months ago but the man himself still hasn't been identified.
Someone also on the investigators list to speak to is the person who tipped the contents of the suitcase out behind the bushes. Officers say this person isn't in any trouble, they're just looking for information.
