A Haitian judge has indicted 51 people for their roles in the 2021 assassination of President Jovenel Moïse, including his wife, Martine Moïse, who is accused of being an accomplice, despite being seriously wounded in the attack.

A 122-page copy of the indictment by Judge Walther Voltaire that was provided to The New York Times does not accuse her of planning the killing nor does it offer any direct evidence of her involvement.

Instead, it says that she and other accomplices gave statements that were contradicted by other witnesses, suggesting that they were complicit in the killing. The indictment also cites one of the main defendants in the case in custody in Haiti, who claimed that Mrs. Moïse was plotting with others to take over the presidency.

The accusations echo those contained in a criminal complaint filed by a Haitian prosecutor and submitted to Mr. Voltaire. The official charge against Mrs. Moïse is conspiracy to murder.

A lawyer for Mrs. Moïse, Paul Turner, did not immediately respond to a request for comment.

But Mr. Turner, who is based in South Florida, had earlier denied the accusations in the criminal complaint.

“She was a victim, just like her children that were there, and her husband,” he told The Times. Mr. Turner said his client is in hiding and her current location is unknown to all but a few people.
