Wick Effect combustion, th phenomena mistaken for spontaneous human combustion whereby the fats of the body burn like the oil in a candle, but the clothing of the body makes up the wick. Very high temperatures are reached and all that remains are the extremities of the hands and feet which can be recovered after the burning either as trophies or burned in a cremulator to destroy the remaining evidence.
However a recent killer tried this technique and was descovered as he didnt do the wick effect combustion propperly.
It must be an art in its own right.....
I love the series Dexter, I just find it really disturbing that I find myself sooo curious as to what is happening next....
