This made me remember a news story out of Mississippi last year of hundreds of graves behind a jail with no accountability of whose body is placed there.
It only came to light after much struggle from people searching for missing family members. Basically people in police or jail custody who died were dumped in there under a blanket assumption that no family had claimed them, but no attempts to notify or find family members was made.
