That's what I was wondering.  How do you get injuries post-death?  If a person fell in the midst of a heart attack or stroke or aneurysm or something, maybe hit their head, I can see how that could be.  Just can't think of any other reason you'd have injuries.  I feel sad that this poor lady died like that in her driveway regardless of how it occurred.  I hope her family finds some peace with this in time.
