I further cropped the pic you posted to make an observation (which likely has been brought up but there's no way I can keep up with the speed this thread is going).
My observation is this...
1) It's very "splattery" in this further cropped pic. I'm talking about the teeny-tiny splatters that look like speckles, not the larger drops:

2) The blood appears to start at that spot. IOW, I believe she was likely punched in the face and perhaps that might be from a nose bleed, and boy can noses bleed. I came to that conclusion because there isn't any visible blood on the step.
So she made it that far, then what happened to make her bleed? Also, those torn plants right there. Was she drug away and she tried to grab on to anything? Even if that's the case, why did those plants end up exactly where they are? It's not like they were inside the house and got drug out through the door. That would make sense of their placement but that's not the case here.
If she was hit in the face or head, and has mobility issues, she likely went down. Brick isn't forgiving. Thankfully there isn't a blood smear on that step cuz that could really cause a bad head injury.

So, if 'stuff went down' on her porch... why did it start there? Did the person ring her doorbell or knock on her door? Maybe saying something like "Fire department!" to get her to come to the door? I've tried Googling to see if there was a struggle inside the house and as I said... I just can't keep up with y'all!
And do we (i.e. - You all) know if she actually ever made it into the house after being "dropped off"?
