One thing we can assume based on Skyla's autopsy is that the killer was shooting from a vehicle or was taller than the girls - the body shots went rather downward from the entrance wounds. The other thing is that I think this was one killer (not two) since Skyla was initially shot from further away than Taylor.
I agree that the killer was either taller or was shooting from a vehicle. However, if it was a single shooter as you surmise, the person, if shooting from a vehicle either has to be a very good shot through his/her vehicle (driving south and shooting through the passenger window), or he/she has to be driving north and shooting from the driver side, and therefore left-handed.
The trajectories don't appear to be angled enough for a person to be standing in the back of a pick-up. So, if it was a single person, they had to get out and shoot at least one bullet on each girl up close: Skyla's with residue and Taylor's groin shot since it traveled up from the entrance to the liver and diaphragm area.
So, if the person IS driving in an auto, they have to be a really good shot if right-handed, or they have to be left-handed. The only other theory I can come up with is someone possibly sitting in the bed of a pickup and shooting from there as they go by.
I'd suggest someone ambushed them, but they were shot from the front (from where they were walking), or from the east of the road, but if the killer did walk, they were fairly close when GPa was around. I just don't see the girls approaching a stranger in the road, so I think a walking ambush by the killer was out of the questions.
Skyla is definitely retreating as she was found 5 feet from Taylor AND her head was laying southwest. She must have had time to turn her torso somewhat and expose the right side to the killer.
Taylor's hand wound is probably defensive and thus the second or third shot.
I think there are two killers. I just don't see one person being able to do this with two guns in that short of time, with the other considerations of shooting style, etc.
