Former Haitian justice ministry official Joseph Felix Badio may have ordered the assassination of Haiti's President Jovenel Moise on July 7, a Colombian police chief said on Friday, citing a preliminary investigation into the murder.

An investigation by Haitian and Colombian authorities, alongside Interpol, into Moise's killing has revealed that Badio appeared to have given the assassination order to former Colombian soldiers Duberney Capador and German Riverafor, three days before the attack, General Jorge Vargas said in an audio message sent to news outlets by the police.

"Several days before, apparently three, Joseph Felix Badio, who was a former official of (Haiti's) ministry of justice, who worked in the anti-corruption unit with the general intelligence service, told Capador and Rivera that they had to assassinate the president of Haiti," Vargas said.
