Sao Paulo: Brazilian police officer may have taken part in the murders of 13 gay men in a lower-class suburb of Sao Paulo. These murders occurred between February 2007 and August 2008 at Paturis Park, which is a relatively well-known meeting point for gay men in the area. 

No one has been arrested in this case, and the department refuses to share too much information for fear of jeapordizing the accuracy of the investigation. If the policeman turns out to be involved in these murders, this would speaks worlds of not only the civil rights in Sao Paulo but also of the political development.
