How do you really feel about it? lol. If Brian did kill Gabby, what possible reason do you think he had? Does that change anything?
As of now, no one knows who or what killed Brian, it's still a mystery. How did he end up underwater? Is it possible he drowned himself? Maybe someone saw him and took the law in their own hands?
You figure if a person spends many hours at a park and is experienced in outdoor camping, he would of been a little more careful. To me it points to suicide or foul play. Can't really see it any other way right now.
Just trail blazing in the middle of no where shows a lack of caution, it reminds of the story of the guy who just left college and moved to Alaska, but later starved to death. Maybe Brian ran out of water or food, got weak, fell down, and animals had dinner?!?!
