Ecuadorian presidential candidate Fernando Villavicencio stood up to organized crime just days before he was assassinated in Quito at a campaign event Wednesday. According to the Ecuadorian newspaper El Comercio, at least six people have been arrested for their alleged participation in Villavicencio's murder. Not long after the shooting, a criminal group known as Los Lobos claimed responsibility for the act and issued a death threat to another Ecuadorian presidential candidate, businessman Jan Topic. Police and emergency workers stand outside the clinic where presidential candidate Fernando Villavicencio was being treated. We suffered it with the assassination of Luis Donaldo Colosio," he said, recalling the Institutional Revolutionary Party candidate assassinated in Tijuana in 1994.
