The aim of this article is tho present a work based on published data about one of the types of homicide and suicide, known as homicide/suicide, H/S. How to understand something, a drama, in wich the main actors are dead? The way to understand the H/S is not to begin based on a wide theory without factual-empirical basis, but to construct a theory based on empirical data. As there is not H/S information, researches or database in Brazil, this article is based on international information and references.
