Change the OP to reflect what you can corroborate with strong evidence or conclusive proof.
There is absolutely no way Bruno would be a scammer.
If the account was/is under the control of someone else that if fine flag it until we get it sorted.

There is no evidence to say Bruno himself scammed you. Best not to claim that or even simply it.

Flagging the account is fine. Better to wait for some more investigative work before bruno is a scammer.

How hard can it be to confirm someone died?

Bruno would have found out and posted conclusive proof by now.
