Vanguard correspondent Mariana van Zeller and producers Darren Foster and Alex Simmons have been reporting on Rio de Janeiro's efforts to secure the 'Cidade Maravilhosa.' On April 7, 2011, they were with Brazilian police when the first reports of a school shooting came over the radio. According to UNESCO, Brazil ranks second in the world for gun deaths -- but this mass shooting was outside the normal scope of violence here. On the local news, it is being compared to Columbine. 'Vanguard,' airing weekly on Current TV Mondays at 9/8c, is a no-limits documentary series whose award-winning correspondents put themselves in extraordinary situations to immerse viewers in global issues that have a large social significance. Unlike sound-bite driven reporting, the show's correspondents, Adam Yamaguchi, Kaj Larsen, Christof Putzel and Mariana van Zeller, serve as trusted guides who take viewers on in-depth real life adventures in pursuit of some of the world's most important stories.
