Oliva Solarte, 61, talks to a policeman after arriving in Mosquera, Cundinamarca province, near Bogota July 16, 2009. Solarte has spent twelve days walking 500km (248 miles) from Aguachica in Cesar province as a protest to call for the release of her son Jorge Trujillo, a policeman who was kidnapped by FARC rebels ten years ago.
