CARTAGENA, Colombia — For a champion of peace, Leyner Palacios faces a lot death threats. The latest menacing message came in February, when Mr. Palacios, 47, was warned he had 12 hours to leave the region where he was born on Colombia’s Pacific Coast, and to “never come back.”The last time he had received a similar warning, in March 2020, one of his bodyguards was killed. So Mr. Palacios, who served on Colombia’s Truth Commission, announced on Twitter he was going into hiding for a while. “I do not want them to see my coffin full of my unjustly murdered body,” he wrote. “I have understood that the threat is the door to the cemetery.”The 11-member commission spent four years investigating every aspect of Colombia’s conflict, which was fought between government forces, left-wing guerrillas and right-wing paramilitary groups from 1958 to 2016.
