I definitely think it is two locals up to no good.

Both would still be shot at close range.
It will be interesting to know if the frontal shots were done at an angle showing the direction where the shots were fired from. I think once murdering these poor girls they swung their vehicle around and headed the opposite way from where they had come from. Within minutes imo, they were back home as nothing had ever happened.
