Colombia should ensure that the investigation into the attack on a leading investigative journalist thoroughly examines possible motives related to his work and identifies all responsible parties, Human Rights Watch said today. On the evening of May 1, 2013, gunmen opened fire on the car driven by Ricardo Calderón, an editor at Semana magazine, Colombia’s main newsweekly, as it was stopped on a road between Ibagué and Bogotá. Five bullets penetrated the body of the vehicle, but Calderón escaped without injuries.
