So...does this make sense?

These are a couple paragraphs from the novel I'm working on.  I really like the idea of a deep fried zombie, but i'm unsure as to whether or not the way I've written it explains what happened.  I figure this is a perfect place to see if I need to drastically adjust this part or not.  (this is first draft, so I know it will need some honing).  The question is: do you understand the source of the zombie's wounds, and do you guys think it's a good enough description? On the flip side of that, is it too obvious?

Fifteen feet from them, the naked corpse of Judith Spitzer squatted over two bodies, blood smeared over her face and body.  A carving knife protruded from her chest, just above her left breast.  A large blister spanned from her neck down to her hip, covering the right side of her body; it looked as though she’d been burned.  She was chewing ravenously, bits of red meat dangling from her lips.  The monstrosity didn‘t notice Collette and Rodney; its focus seemed to be on its meal: a young man wearing a chef’s apron.  His throat had been torn out.  Beside him, a middle-aged red haired woman, similarly dressed, lay face down in a deepening pool of blood.
    As the creature fed it rocked sporadically from side to side, every so often its thigh or foot glancing against a large frying pan on the floor, eliciting the clanking sound that had drawn the two security officers to it.  Collette realized the source of the dead woman’s burns when she saw that the floor looked slick with cooking oil mingled with blood.
