Ya, I think it is safe to rule out that series of events before we find the other black box. And by the way the survivability of that box is iffy. There is a reason why the bodies are smashed to smithereens and are mostly gone.
I am usually on board requests to not rush to judgement but not here, we have enough evidence to conclude beyond all reasonable doubt that the FO is a killer.
