For some extreme speculation: Perhaps someone (with a white ute) is growing a cannabis crop at the King Billy/Bluff Track. They live in Bairnsdale. They travel up to to the location on March 19, via Dargo, then stopping at a toilet/suspension bridge (Eaglevale). There is an encounter/attack at Dry River Creek where RH and CC are camping, perhaps spurred from previous antagonism in early March with RH at the King Billy/Bluff track. RH and CC are removed from the site, after 6.30pm (radio call), but not too much later (toilet unused), then the tent burned. The white ute freaks out, takes a back road to Harrietville, spending a few days doing so, perhaps disposing of evidence. From Harrietville, then heads back to Bairnsdale - via the Olive Branch chain bay (were objects thrown from a car heading south? i.e. downhill) and Dargo. Speculation only!
