its only 1500 degrees Fahrenheit to turn bone to ash crematoria dont do this because its cheaper to just burn of the flesh and meat the crush the bones and a blown furnace definately gets hotter than that

a couple points 1 a burnt body is gonna be hard to id either way even if you have bones left dna is gonna be destroyed 2 wind blown fire burn way hotter forced induction is how a blacksmiths forge works 3 The reaction of the government here is more interesting than anything and with known instances of arson with candian and west coast forest fire i dont think its a stretch in hawaiis case
