Yeah, I hate everything about the article, especially the self-assured 'expertise'. At no point does he address e.g. the possibility that the blood was not hers but someone else's.

Both of these second opinions gave the option of blood splatter from another person. Assuming that this is spray from another victim, then there should be droplets all over her face. I count seven possible drops on her forehead, one on her nose, and no others. Searches on Google Images for "arterial spray" and "blood spray" turn up a lot of disturbing photos. But all the photos have something in common: lots of droplets. If her face got splattered, then she should have droplets all over her face. I would have also expected her clothing to have visible droplets.

Edit: missed the part where you were agreeing with the article, apologies for assuming. He does indeed address that, poorly!
