He ran out of gas and probably being on foot the State Trooper thought Brandon was with them. He clearly states "I wasn't talking to them, I totally ran into them" Meaning I have nothing to do with this. I think he also says the first guy was shot and taken into the woods. I can definitely hear what could be gun shots. If so they are pretty far away. At that point I think Brandon panicked. Brandon mentions woods when talking about the "first guy" and Brandon clearly states he's in the middle of a field. From where his truck was parked it should have been too hard to figure out where he was. Of course with 6 years gone by that time has passed and even if they could figure out where these two areas are the likely hood of finding blood or anything that could help is slim. I would still search the area though.
