How dense is the woods there? Are there tracks for either trucks to get through or powerlines near the road where the girls were walking?
It looked like it was too heavily wooded right there to get back into the woods for vehicles, but running near the site, cutting deeper into the woods on google, there looked like a utility clearing.
"He said an aviation unit with the Oklahoma Highway Patrol was also helping to scour the scene for clues."

Walking in the ditch on the side of the road, maybe they were looking for turtles since they loved animals. A country road like that; there are no rules and people could just walk anywhere on the road. Would the girls have wandered into the woods a bit looking for animals and saw something else?
With her love of animals it is possible she would go into the woods, but they knew they were short on time. (I would assume they knew the mom would be coming soon and why they didn't stay at the bridge long.)
If they made it to the bridge, then turned around (not even seeing anything) yet turned around when their cell phone rang; maybe a culprit heard their phone and assumed they witnessed something. If the girls had seen something, they would have started running or used the cell phone. Walking back from the bridge, on the road next to the woods; is there anywhere in the woods that a meth lab could be stashed?
Yes, it doesn't take much space to stash the whole cooking process and supplies. They run across the materials dumped all the time and have to call a special team to collect them.
If it was a thrill killing, then local boys should be looked at. Execution styles are show in movies and video games. The u-turn the vehicle made was away from the direction the girls lived, correct?
They haven't said which direction the vehicle was going...only the girls.
Then one would think they knew that houses or at least the girls' were in that direction. To pull a u-turn is harder than to keep on driving in the direction they were originally facing.
The road was quite wide enough to do a u-turn without any problem.
