I keep hearing that Brian is not a suspect, just a person of interest. If they can determine the time of death was near Aug 27th, the day the van was spotted, 900 ft from where the body was found, can't they begin calling him a suspect? And wouldn't that change the parameters of the "search" for him?
I am a little surprised at that, BUT I think all resources have been called out at least now in the search. Not sure what else would change at this point by changing that designation.
