Just so we are clear about this - I have no intentions of contacting Bruno's relatives, nore would I have phoned his number when it was made available earlier in this thread) - If there is agreement about the funds I am holding on behalf of the Known Alts Group, then I will either transfer the funds to the 1F wallet address as Bruno requested, or, if it looks as though the funds are going to remain untouched, I would look to do something else such as forward to the funeral home that posted the obituary, or at worst, the hospital that last treated him.
It might sound cheesy, but the funeral home also had a "buy a tree" link, so that might also be something worth doing.
