There is an overlap between underground cave systems and disappearances
Even in a hyper-connected world such as the present one, people keep disappearing without a trace. Missing person cases are tough because the victim’s families never get closure. This next pic illustrates a possible connection between disappearances and cave systems.
It seems that more people vanish without a trace in areas where there are more caves. Of course, we cannot be sure that these two things are truly related, given that the regions with the most missing person cases include some of the most populated cities in the country.
