Fire authorities say a bushfire that started at Dereel yesterday is being treated as suspicious. Firefighters have contained the blaze, as well as the 22,000 hectare Bayindeen fire.

This may be unrelated but its barely a 30 minute drive south of Ballarat. Could perhaps be to incinerate evidence, phone, watch, airpods, clothes and or anything a perp may have been wearing or using at the time of disappearance away from the search areas. Maybe someone taking a car apart bit by bit or how effective that may be in destroying forensically gatherable (probably not a word but, as the kids say "tevs") traces. It doesn't seem to be the smartest choice but someone who is panicking, desperate or under intense pressure about following an order might feel they have no other option.
Or possibly as I recall from an earlier thread it could be a ruse to divert a large contingent of fire fighters and emergency services to this area while they incinerate a vehicle/evidence elsewhere.
Really hoping for closure for Sam's loved ones, especially her children.
