We sure don’t. It’s only when these questions come up sometimes that you become aware of your assumptions. I’d just assumed he was in a typical tradie ute with a hard canopy and a big toolbox. He could’ve been in anything.
I know they took his ute away for examination, .. one could assume that's what he did use, but ....
He’d know to turn his phone off. He’d know it’s a tracker. Someone turned her phone off which indicates tech awareness. He’d be receiving calls though and he’d know he wouldn’t be able to have it off for long as it’d draw attention. Maybe he went straight home from Woowookarung, then ventured out a few times after that, just to stay under the friends & family radar. On whilst home, then off for brief interludes.
It gets more difficult to believe he kept track of all these monumentally important details, one after the other, many all at once, and be ''heavily intoxicated' at the same time.. I don't believe he was, mainly because of the myriad details, all of which he had to keep a tight reign on, we know he made one , maybe more than one colossal error, but he still kept track of a lot of stuff, for an early Sunday morning after a bender. ..
