This is really bothering me - this whole scenario of Holdom and Karlie going to Belanglo and her ending up being killed there (I'm assuming this information is correct, which it may well not be, given the previous inconsistencies, but just working on this scenario).
"What would be serious enough to commit double murder to keep it quiet ..." The thought popped into my head - what if Karlie was pregnant and told Holdom whilst they were at Belanglo and he snapped, or indeed before they went to Belanglo, in which case Holdom may have already premeditated the outcome, or she was pregnant and opted for an abortion. I know this isn't a pleasant thought however, the stomping being so personal (if indeed, she was stomped on - I'm only going on what we know from the somewhat flaky media reports) and the area of the body where she was allegedly stomped on, made me wonder if it wasn't a very, very personal rage being inflicted on her.
As I said, sorry for the line of thought, but as we all know, there is nothing pleasant about murder, full stop. And there is never a pleasant motivation behind it.
All the above is viewed only as speculation of course.
Now this is a real possibility, especially if he had plans to head back to HP at some stage.
Its a new relationship, they have been on the road for weeks/months, mistakes can happen in the heat of the moment. Perhaps she fell pregnant and it didnt fit his plans.
It would also support the notion that Khandalyce was killed in a rage directed at her mother for 'giving him no choice' as referred to recently when discussing the possibility of indecent activity.
I wonder if pregnancy could be determined through DNA profiling?
