This July 13, 2016 photo shows a crime scene at the entrance of a home in Nova Iguacu, greater Rio de Janeiro, Brazil. The man who lived there with his family was removed by gunmen and killed on the spot. Police believe the killing was a gang hit related to a change of leadership in the area. On the eve of hosting the world's largest sporting event, Rio's decade-long push to curb violence in hundreds of slums appears to be crumbling. Overall murders are on the rise in the first half of 2016. (Photo by Felipe Dana/AP Photo)
