Spontaneous Human Combustion could be the cause. In the picture you've drawn, i notice that the limbs are still intact. That's a common factor in these incidents. Its very rare, but possible. Its often accompanied with an oily, yellow substance left behind on nearby objects.
GAH!!! Personally there I think there is two option, 1 She killed herself by setting herself on fire, which I think is just stupid considering there are other more easier and less painful methods of suicides, she either had a high pain tolerance to not to scream or she already had drugged herself so she couldn't feel a thing. 2 If she was murdered and clerk heard or saw nothing, that would mean that her head was bashed with a blunt object before she was fired up and it's not out of option that the Clerk had some part in her death. other thing i'm curios about, clerk said he Didn't hear or see anything but i'm pretty sure he would have smelled something, like burning cloth and meat.
Now, I don't know anything about this, BUT. IF. this was a murder, I would imagine it went down something like this:
Woman gets knocked out, killed with severe blow to head from behind.
Killer douses the body in gasoline, sets it on fire, as to eliminate some kind of trace he thinks he left on the body.
Killer runs away, clerk finds the body later.
I really want to know more about this now... see if they released any information about this...
O
