Check this out. The tracks are heading back INTO the theater. Something definitely went down behind the theater with the victim running in.

Google video image showing how far the victim ran.
This aerial photo shows the shooters car parked by the back door to theater 9.
The blood spatter pattern suggest an arterial bleed. The evil in this photo is surreal.
What I don’t get is why does the pattern seem to appear as though the direction of travel was INTO the theater?

Notice how the blood pattern begins on the sidewalk to the right of the photo and progressively shows more and more blood and a larger pool at the door. Was someone shot outside and then they turned to retreat and go back inside?
