A report may have been made in a different country, to a police force distant from where the body was found, or may have been recorded many years before, archived and forgotten. Perhaps there has been no report at all because nobody realised the person was missing, or there was no one who cared sufficiently to raise the alarm. Some may see that as a sad indictment of society but the fact is that some people do not want to interact with others or to be part of a community, and as long as they are doing nothing illegal, their right to privacy and anonymity has to be respected.
