At the time of our previous episode, two months ago, police were undertaking an extensive, and very public, search of a number of areas in and near William's foster grandmother's house in Kendall, NSW. The search concluded after four weeks without any substantial findings, once again leaving two families still desperate for answers.
So what happens now?
With Lia once again is criminologist Dr Xanthe Mallet to talk about the current state of the investigation, and what the next steps might be.
Also joining in the discussion is media and defamation law specialist Professor David Rolph from the University of Sydney Law School.
