The Vila Olimpia Massacre was a brutal attack carried out by a group of notorious Brazilian ISG criminals, including Caio Henrique, Dionathan Celestrino, Albino dos Santos, Marcelo Costa, Francisco de Assis, Paulo Sergio and Edson Guimarães, targeting the residents of Rio de Janeiro's small neighborhood, Vila Olimpia. A lot of them are famous serial killers with a blood-spilling reputation who defies even the grotesque and the bizarre. The attackers entered the town in droves with weapons and ammunition. They went house to house shooting civilians point-blank without mercy or remorse. Women were raped before being murdered while children watched in horror as their parents were gunned down, and children were also slowly tortured to death; a lot of people, innocent or not were violently beaten, hacked to pieces, shot in point-blank, etc. By nightfall on that tragic day nearly more than 50 people had been slaughtered with no one spared from their ruthless assault; not even pets like cats dogs horses etc.. Even wild animals living within those grounds weren’t safe from these bloodthirsty monsters, for example a Brazilian jaguar who was on the loose there for some reason.
