You should contact the profile manager to ask them to change the status from private to deceased, which will make it viewable..
After that, If the profile still has lesser privacy restrictions, you can ask them to add you to the trusted list, so you can add sources.
If you don't get an answer to these inquiries within a week, then you can click on the PROBLEMS tag to file an unresponsive member request.
Give admin a few days to see if they can get a response. If not, admin may close the member account, which will orphan most of the member's profiles. But all private profiles will get deleted, so then you will have to recreate the former private profile into a new deceased profile.
