My reading was that the second trip was the one on which they disappeared, so that would be one trip the previous week.JLZ--ok, I think your idea is a good one--RH took CC to the Bluff Track /King Billy Track area--where he had been twice in the week March 11-13 to fly the drone before heading to the W. Station to make his last known call on March 20th. So what do you think happened there?
I don't know . . . I think the general area has an intrinsic appeal, I don't have to imagine a specific motive like irregular farming to explain revisits. As for the intersection, I can see the attraction for a Button Man character, there are the two tracks I mentioned joining Mt Clear Track and Brocks Road, plus the Australian Alps Walking Track parting from King Billy Track within a hundred metres, and it's high ground, about 1600m (compared to the Wonnangatta Valley at about 600m), with several higher peaks very near. But for practising droning? not so much. It's steepish and looks moderately wooded (going by Google satellite). So, was there a reason Russell picked that area, and did it have to do with Button Man or perhaps another person who'd made a regular base there? And if he was prying into someone's territory, could that be sufficient reason not just for an immediate confrontation, but to follow him away from the camp and kill two people? I'll leave the question open, but at the moment it feels like a stretch; and I note that Button Man is said to have no criminal record. Apparently not someone who seeks lawbreaking thrills.
In those missing hours, did they perhaps meet up with someone previously known to either, perhaps reinflaming a longstanding grudge?
