Seems that not all curmudgeons are old men..

Resuming lurk-in-shadows mode.
Nor are all old men curmudgeons.
Just a thought, why would anyone feel the need to cremate a body without the family’s permission?
Perhaps to eliminate any drug or poison residues that might linger in the unburned body core?
Or perhaps, just perhaps to conceal any deep shrapnel damage that was beyond the reach of the car fire and to facilitate separating the shrapnel from the body? It’s a lot easier to run a magnet over ashes than to dig around in a badly burned body.
