Anyway, the truth is that even if Bolsonaro while in Congress murdered people with a chainsaw (he wouldn't be the first case), he couldn't be prosecuted for it until he leaves office.
Personally, the story seems a little fishy for me, less the ties of his family to this sort of organized crime (which seem pretty obvious), but rather tie him to this specific case seems non-sense, and less than one week after a witness tied Lula to the murder of his former campaign manager Celso Daniel (which is something the victim's own family already indicated to believe for a long time) seems a hell of a coincidence.
