I was just reading back over my post from last year in June on here.
I still hold this theory.
There has to be another person who used that passport JMO MOO
" Knowing that AH could not have possibly been able to marry Marion in Lux or that she was even there- having found no evidence of, I am more convinced than ever before that something happened to Marion in the UK and while her passenger card may have arrived back into Australia, I don't think it was her that carried it in.
His admittance and that of Diane's, that he collects the passenger cards at the 'little stand' and fills out her arrival & departure cards for her - he would have no trouble what so ever getting anyone to prefill the details - especially someone smitten by the creep. Marion prefills the card but leaves the passport number blank for a custom officer to fill in??? Odd thing to do for Marion being a stickler for accuracy no doubt, having been a teacher for years. Left blank because at the time she didn't have access to it to get the number of her new passport, because he would have been holding onto it for her - just like he did for the others - a valuable commodity for a creep.
If she was in the UK in the hours before leading up to the flight home and the plane left Amsterdam not Luxembourg, no reason for her to write Luxembourg (resident) IF she had filled it out just hours prior to flying because she wasn't ever there, she was in the UK and what purpose would it serve her to do so? AH wasn't even with her and IF she had dropped everything to get back because she smelt a rat, all the more reason to fill in resident - Australia, if coming back for 8 days. WHY write home duties on the card if she was rushing back to a rat and filled it out just before the flight, she is a teacher and she didn't have a home, she had sold it and she was traveling through the UK.
Passenger card says she was coming in for 8 days and the passport never left Australia again. He had someone else come in on that passport, another victim from Europe or someone he knew IMO
The unfilled passport number and the big fat tick for married, was filled out just prior to the passport coming back in. IMO Marion had already prefilled most of the card and AH held onto them along with her passport. HOW could she get home without it. "
