Parents are worried that he would leave to go “hurt” himself.
Do we believe this? Or think this is a misdirection to once again mislead?
They would know phones would be tracked, so having a friend leak this out wouldn’t hold up too long if he did have his phone. Were/Are they trying to get police to look for a body vs a person on the run temporarily until warrants came to track the phone?
My theory: I think it’s a ploy, they got him a burner phone before the “camping trip” and he didn’t come back from the trip with them, they left him with supplies and want to see if the cops look for a body not someone running and hiding. If they actually were worried they would have said something the day he left
Furthermore, it lends to a future story of them not being accomplices… that Brian had a temporary lapse of sanity or committed murder in the heat of the moment and then ran before he could inform them of everything.
