I don't believe that is happening, given the information I have at present. And I don't want to call the funeral home anymore unprompted because it starts to seem obsessive and like I'm heckling them. They offered to pass my name and number along to his sisters, which I appreciated, but I doubt I'll be hearing more about the issue, as he hasn't been on good terms with his siblings since he was 20ish.
If someone who knew him better would like to write an obituary I am fine with that, and I would be willing to submit it to the local newspapers. Someone perhaps who was linked to him on Facebook who could get in touch with his wellness contact at his work. Or at least such a person could serve as a better conduit of information.
