I just saw it on the news. I think he may have an hero'd. But it looks like the items were found in a place that had previously been underwater. Although it doesn't say when. So he could have been the victim of flooding. The East Cost has experienced some nasty storms.
I have no doubt those remains are Brian's.
And of course the news outlets also have to mention the controversy over Gabby's case getting attention over POCs. The energy you are using to complain could be put towards raising awareness instead you know.
