I always thought Tanja was reported missing by her family. Michael's sister is definitely his half sister. His brother Mark committed suicide a few years ago.
I'm afraid this crime will never be solved. The person who probably could shed light will never talk. It's so heartbreaking.
I got the distinct impression that no one of the Burdon's actually rang the Eberts.. That the police did, once Michael had shot himself , while the police were there at the sheep station. I don't think they (Michael and Maris , who had a couple of days to get a narrative going ) were prepared to say she was not actually coming home. In fact, Maris, probably still today is adamant that Tanja just 'took off'... like, into the desert, freezing cold nights, 1000klms of nothing, without even a jacket. Gone to buy another property in competition with Michael. So once the police sorted out exactly where Tanja's family was, the SA police took over telling them of her disappearance and Michael's suicide. What a call, ey?
I know the SA police arranged and paid for her family to come to AU, not the Burdon's, which has significance, but what significance I don't know yet.
And thanks for the heads up re the sister, Kakadu, now I recall that Maris came into the marriage with Old Mr Burden, with , I think 3 children, he had, I think 3, and then Maris and Old Mr B had the two boys, quite close together as they went to boarding school together while Maris took a job on the lighthouse island , counting shearwater birds. Albatrosses, petrels, etc. This was after the marriage to Old Mr B had ended. This is where her letters to the rest of the stepchildren make sense.
I was never able to find the coroners report about the younger brothers demise. And now, I do wonder if Maris was actually successful in making this a private Coroners inquest. I would have thought one would have to be the concubine of the Governor General of SA to manage that, but it is something at the back of my mind. They were/are a powerful pastoral Company/family, old South Australian money and that can shout quite loud when it wants to.
And perhaps that old South Australian sheep money may be a reason why the little boys remained in Australia, with the 1/2 sister and her family. The line must go on, sort of thing.
On the other hand, this venture with the special dog may well be at the direction of the Coroner, not willing to go to inquest unless every tiniest straw has been utilized . I like to think that is the case. That the coroner isn't accepting that her remains, and the artifacts she had on her, jewelry, her phone, a watch, maybe , would not survive in the dry desert heat, and just be waiting to be found. I heartily echo that wish.
I believe her whereabouts will be solved, sometime. Someway. He had a lot of time, whichever scenario one chooses, but his most risky one would have been to bury her while he still had the little boys in the back of the car asleep. Could still be done though, but it narrows down his possibilities.
The police went to town on the property, according to Maris, revving the bulldozer that was there to build dams, leaving all the station vehicles without fuel, etc, ….they dug here, they dug there, they emptied dams,.. that presupposes that he killed her on the way home and put the body in the boot,..or.. she actually got home, and was killed there. In that case Maris, the mysterious sister and the 1/2 brother are lying.
Keep in touch! This, to all Ebertians.
