Young couple goes on van tour of US, boy comes back with van - no girl

I think Brian got help from his parents in some form or fashion. I think he's smarter than we're currently giving him credit for. It comes out yesterday that the Laundries went on a weekend camping trip the weekend before he disappeared. Today, a person that knows Brian has claimed he's gone off the grid for a long period of time in the past(months). The reserve is probably a distraction. Did anyone actually see Brian drive to the reserve? Did the Laundries stop anywhere on this weekend camping trip? Where did they go? Was Brian seen when they got back from the trip? I wouldn't trust anything the parents say. Somewhere, a camera must of picked them up while driving to w/e they were going camping. Maybe, someone saw their truck or saw them.
