After two people in the building reproached him, the man withdrew a pistol and opened fire. When police arrived, they found four people with gunshot wounds lying in the building’s courtyard, and shot at the gunman. Paramedics found the gunman dead, along with two other people, the police said. One of three people who sustained injuries died en route to the hospital.
Two things with this very recent shooting outside Mexico's National Palace that is the Presidential Residence for Mexico, is that this event unfolded shortly after the bilateral meeting on Mexican cartel's between AG Barr and Mexico's President. Matter of fact this shooting outside Mexico's National Palace took place three days after the meeting.
We know four individuals were killed in this shooting in Mexico, but the second thing is this may change the minds of Mexico's leadership including it's President if this ends up being cartel related. The most interesting part about this shooting is that this was very shortly after both AG Barr and Mexico's President held bilateral meetings involving discussions on Mexican cartel's. For a strange reason this shooting isn't being covered in the news.
