Contrary to Netflix's dumb English re-title, the mystery is "solved" in the first ep, aside from the question of accomplices and one in particular, and the rest make no real effort to answer that (not entirely the filmmakers' fault) nor many other obvious questions. But it's quite amusing and interesting how venal and incompetent cops, lawyers, and reporters from Portugal, Italy, and now France have come off in these recent Netflix docs, more so than even their worst American counterparts.
