BOGOTÁ, Colombia — Several of the central figures under investigation by the Haitian authorities in connection with the assassination of President Jovenel Moïse gathered in the months before the killing to discuss rebuilding the troubled nation once the president was out of power, according to the Haitian police, Colombian intelligence officers and participants in the discussions.
The meetings, conducted in Florida and the Dominican Republic over the last year, appear to connect a seemingly disparate collection of suspects in the investigation, linking a 63-year-old doctor and pastor, a security equipment salesman, and a mortgage and insurance broker in Florida.
All have been identified by the Haitian authorities as prominent players in a sprawling plot to kill the president with the help of more than 20 former Colombian commandos and seize political power in the aftermath. It is unclear how the people under investigation could have accomplished that, or what powerful backers they may have had to make it possible.
But interviews with more than a dozen people involved with the men show that the suspects had been working together for months, portraying themselves in grandiose and often exaggerated terms as well-financed, well-connected power brokers ready to lead a new Haiti with influential American support behind them.
Christian Emmanuel Sanon, a doctor and pastor who divided his time between Florida and Haiti, conspired with the others to take the reins of the country once Mr. Moïse was killed. During a raid of Mr. Sanon’s residence, they say, the police found six holsters, about 20 boxes of bullets and a D.E.A. cap — suggesting that it linked him to the killing because the team of hit men who struck Mr. Moïse’s home posed as agents of the Drug Enforcement Administration. Mr. Sanon is now in custody.
Haitian officials are investigating whether the president’s own protection force took part in the plot as well, and on Thursday they detained the head of palace security for Mr. Moïse. Colombian officials say the palace security chief made frequent stopovers in Colombia on his way to other countries in the months before the assassination.
The Haitian authorities offered little explanation as to how Mr. Sanon — who did not hold elected office — planned to take over once the president was killed. It was also difficult to understand how he might have financed a team of Colombian mercenaries, some of whom received American military training when they were members of their nation’s armed forces, to carry out such an ambitious assault, given that he filed in Florida for Chapter 7 bankruptcy protection in 2013.
But the interviews show that several of the key suspects met to discuss Haiti’s future government once Mr. Moïse was no longer in power — with Mr. Sanon becoming the country’s new prime minister.
“The idea was to prepare for that eventuality,” said Parnell Duverger, a retired adjunct economics professor at Broward College in Florida, who attended about 10 meetings on Zoom and in person with Mr. Sanon and other experts to discuss Haiti’s future government.
street protests demanding his removal — would eventually have no choice but to step down. Mr. Duverger, 70, described the meetings as cabinet-style sessions intended to help Mr. Sanon form a potential transition government once that happened.
