Open to this theory, but assuming you are correct, why do you think the police are continuing to do so many searches still around Mt Clear?
Where do you think the remains of the electronic devices would be?
And how far beyond Ballarat are you hypothesising the body is buried?
Are you suggesting that the accused had no interest in keeping at least some of Samantha’s personal possessions? No desire for “trophies”?
While I’m open to all theories, my sense is that even if it was an impulsive act it did not come from nowhere. I suspect the accused had preexisting propensities towards violence regardless of whether the alleged murder was planned or impulsive. Things like an insecure attachment style, longstanding insecurities in sense of self, impulse regulation difficulties, labile moods etc. But all entirely just my opinion.
