Brooklyn , New York ( VBS.TV ) -- Throughout the 1990s , São Paulo 's House of Detention contained about 8,000 of Latin America 's most violent criminals . Better known as Carandiru , it was once the largest prison on the continent . On October 2 , 1992 , a massive fight broke out in the Brazilian complex among the prisoners . It ultimately resulted in 111 inmate deaths . That day , there were 84 state military police officers present , and 102 bullets were fired . The nine guys who were n't shot in their vital organs got knifed , but the cops ( none of whom were killed , by the way ) swore that the prisoners were already carved up by the time guards arrived . In the archival images we collected , we see one inmate partially decapitated and another with a hole in his chest the size of a tennis ball . That does n't exactly scream self-defense . ( The footage is graphic , so be warned . ) See the rest of Carandiru 's Bloody Memories at VBS.TV . Ronaldo Mazotto de Lima worked at the prison for over a decade . He was also one of the first people to witness the aftermath of the carnage that 's now referred to as the Carandiru Massacre . After the jail 's destruction , Mazotto de Lima transferred to a minimum-security prison in Serra Azul . He brought more than his experience to the new job . He also took along some of the only surviving evidence of the massacre : More than 2,000 photos , 300 personal effects and 10 hours of grisly video footage . It was all taken shortly after the violence subsided , and he wants to be sure that history does n't forget what he witnessed . So we asked him to help us understand . An edited version of this article originally appeared in Vice magazine .
