Moïse, 53, was fatally shot early on Wednesday (local time) at his home by what officials said was a group of foreign, trained killers, pitching the poorest country in the Americas deeper into turmoil amid political divisions, hunger and widespread gang violence.
Colombian Defence Minister Diego Molano said initial findings indicated that Colombians suspected of taking part in the assassination were ex-members of his country's armed forces, and pledged to support the investigations in Haiti.
