According to this Facebook page, Joseph Osell Frazier has been “recovered.” The posting that says this is about a week old and I can’t find any corroboration for it. He’s still on NCMEC. If he was in fact recovered I’m assuming we’re talking about his body being recovered, since this was almost certainly a drowning.
[UPDATE: Hmm, it looks like the Facebook post about Joseph being found has been deleted. There is a registered sex offender (rapist) in the state that’s got the exact same name as Joseph, is the same race and about the same age; maybe they saw the listing and thought it was the missing boy? It’s not though.]
