Yes, I thought it was quite a significant amount of blood also. Looking at the pattern of blood spots, I'm sure that there is also some on the mat. Then, there was some apparently on the walk all the way to the car, although from what has been posted here (I haven't seen it) the number of blood spots diminishes after they leave the porch. Of course, we don't know for sure, but I'm envisioning that the blood started inside the house and we're seeing the higher quantity of droplets at the porch as the perp likely slowed down while exiting the house - getting her through the door. If that is the case, that they started inside, it really is quite a bit of blood. If it's a simple nosebleed, it's a gusher! All this tells me that there was likely a fairly violent incident inside the home. I've come to the conclusion that she most likely was killed in the home or died soon after leaving it. Any way you slice it, very, very sad.
