Most of the blood seems to be coming from her head, Don will find if he examines her upper half more closely. She's bleeding from the top of it, around old scar tissue. She's breathing too, if shallowly. She's just not conscious.

She moans, lowly, making it unmistakable that she's still alive somehow.

There's a loose brick lying close to her, blood on one side. It's not too hard to reconstruct the circumstances of her wounding.
