This is a guess,based on what I know,while cutting down on speculation,and possible scenarios,with some main points in place,the police may know more than there telling,obviously.Here goes-Didn’t Russ report that he was having radio issues to someone?Camp got setup,I presume they wouldnt use the drone that night or sleep with the drone,so it would have been in the car,safe kind of spot.Thats where I,d put it.The mobiles probably in the tent where their sleeping.(is there reception out there?).I mean where else would u have them.Carols belongings found in the car.(which ones?),(where’s Rusty’s wallet and keys?)The fire very neatly done.Possibly misadventure,I,m leaning towards a controlled burn given the possible circumstances.Somebody waited till it was properly done,I’d believe.(waiting seems risky and a weird thing to play out)but there’s a reason for that fire.They disappear,Mobiles and Drone Gone.Rustys Wallet and Keys gone(could be incorrect).I mean those things weren’t in the fire or found elsewhere,were they?I think that overthinking this could give the wrong conclusion.Now here’s some points,Why would a robber killer take mobile phones,truth is,they most likely wouldn’t,they maybe traceable.Why not just take out the battery an throw em in the fire?Why take the phones for a ride couldve destroyed them there,the camp burnt up looked bad enuf,maybe it was decided after handling them to rid em elsewhere.No talk of the phones leaving there camp.Were the phones off?When we’re they switched off?If stealing a Drone,money would’ve been taken too,untraceable,a thief is a crook,Wasn’t Carols belongings in the car.(anything missing who knows)But Rusty’s Wallet And Keys have taken a walk I red somewhere.(Maybe incorrect).Even if something went down at the campsite,with the Drone,Phones,Rusty’s Keys and Wallet being on the table,or in ones possession theres still things that don’t add up.Even stealing this Drone risks perps getting caught.Couldve stolen it without abduction and murder.If robbery was the reason for all this.Based on this particular line of scarce information.I see there’s some things which don’t fit the MO of perpetrators.And this kind of random thing just doesn’t occur in Australia,it’s very rare indeed.Which leaves other seemingly unlikely reasons for all this as well.That may not be impossible.
