Subject: could spontanous human combustion be caused by a chemical reaction?

Since the body is 70% water, and water is composed of hydrogen and oxygen  
(two highly flammable elements when separated)could SHC be caused by a 
chemical breakdown of the body's water, instead of the theory that the 
water is simply burned off.  I wonder if this process could be 
triggered by an electrical current flowing through the body?

I already read the similar questions and answers on your site,  and it did not 
answer quite what I was asking.  Thank you, D Miller
