Guillermo Cano Isaza was a Colombian journalist. The editor of the daily "El Espectador," he was murdered in front of the paper's offices by two hitmen linked to Colombia's drug cartels. It was assumed that the attack was in reprisal for a campaign he had launched in the paper to denounce the influence of drug traffickers in the country's politics. The same building was destroyed in a bomb attack three years later. Wikipedia
