¿Dónde están?()

October the 2nd of 1968 is still a reference date of the modern history of Mexico. However, we began a search for the bereaved (direct relatives of the deceased). It has been a pending investigation, in 46 years of history, no one has approached them. Researchers, historians, writers, activists, journalists, government, etc., no one had visited these directions, despite being public and accessible to anyone. The ultimate question is where are they?
