A family representative told 9News that Ian is continuing to show signs of improvement as he waits for a liver transplant.

Patterson had little to say to journalists who were waiting outside the office of her lawyers in Melbourne’s CBD today.

She has denied any wrongdoing.

Detective Inspector Dean Thomas told media earlier this month the investigation was “complex”.

“I would like to say that because the Homicide Squad is investigating this matter, it doesn’t automatically mean that the deaths are suspicious,” Thomas said.

A public memorial for Don and Gail Patterson will be held this Thursday in Korumburra.

At this stage, Patterson has not contacted any members of the family to confirm whether she plans to attend the memorial.
