I listened to the 911 call when it was released (unless what I heard was an edited version). The shock we hear from the bystander, and the gf's description, did not necessarily point to any specific wounds, I didn't think. We hear her say "she's like dead, dead," and here she says there was a lot of blood and her neck was slashed, so it was clear she was dead. Of course, none of this speaks to injuries elsewhere on the body, but there's nothing that jumps out at me as face specific. I could be wrong, and maybe I haven't heard it all?
