Damn, they just kill people so casual like checking out a book, like it`s no big deal. Cancelled my trip to Sao Paulo and instead going to Italy !! After I booked my hotel in Sao Paulo, I read a review that some woman posted saying there were signs all over the hotel property that said beware of being robbed, even in broad daylight.
This murder was gang related. In Europe are plenty of scumbags too, thieves and assassins. Good luck.
