Vincent was arrested days after the attack alongside another Haitian-American, James Solages. Both men initially said they were hired by the conspirators as interpreters.

At the time of the attack, the gunmen reportedly masqueraded as DEA agents, though the DEA later said neither Vincent nor Solages were acting on behalf of the agency.

A court filing, signed by Vincent, said he had provided material support and services to the plot, including advice about the political landscape and meetings with key community leaders.

At these meetings, the filing said, Vincent often wore a U.S. State Department pin leading people to believe he was employed by the U.S. government.

Vincent traveled to Haiti early in 2021 to back Florida-based pastor and co-defendant Christian Sanon's bid to replace Moise, according to the filing, and on the night of the attack was a passenger in a vehicle Solages drove to the president's home.

Vincent's guilty plea follows those by former Haitian Senator Joseph Joel John, retired Colombian army colonel German Rivera and Haitian-Chilean citizen Rodolphe Jaar, the latter accused of helping supply guns and vehicles for the attack.
