Probably easier for the defence in some ways to say, well, there's nothing there.

There's nothing here to prove what you say has happened.

I'm not aware of anything like this in Western Australia.

There has been at least one other case in Australia that I'm aware of, of course, is Chris Dawson, that bears similarities.

No body, a circumstantial case, sort of pieces of a jigsaw being put together.

So in March 1986, according to her husband, he'd said that he'd come home and she wasn't there.

But then he later said that he had dropped her off at a train station, so he gave different versions of events.

But the last time anyone actually saw her was her children in the morning.

They were being prepared to go to school, as she usually did, various schools, high school, primary school.

And in the case of Heath, a place called the Sound and Coordination Centre in Wangarra because he was only three years old.

So the children would have been the last people to see her alive aside from her husband, Robert Fulton.

So the court heard that she had dropped her son Heath at the Sound Coordination Centre in Wangarra.

So the family home was in Duncraig, which is a northern Perth suburb, and Wangarra is slightly inland.

There was a plan to go to something...

that was known as a print party, a bit like a Tupperware party where people turned up to have a look at decorative prints.

And this print party was going to be held in Bayswater, which is a suburb closer to the Perth CBD.

And the plan was that she was going to go there.

She did actually ring the house and say, can I bring my son Heath?

And she never arrived.

So Derek, being in his mid-teens, he was the one with the clearest memories of his mother.
