There have been several obstructions and irregularities in the investigation into the murders, originating in the police, parliament, and the executive branch. In 2000, supporters of chief suspect Dany Toussaint, some of them armed, threatened to set fire to the courthouse, and in 2001, Toussaint (then a sitting senator for the Fanmi Lavalas party) claimed parliamentary immunity from appearing in court, which the senate refused to revoke. The president of the Senate, Yvon Neptune, pronounced that a “little judge” could not summon a senator. The Minister of Justice at the time, Gary Lissade, had previously been Dany Toussaint's attorney. The first judge in the Jean Dominique case, Claudy Gassant, was subject to repeated threats to his safety, and in 2002, Aristide refused to renew his mandate. In March 2003, Judge Bernard Saint-Vil concluded that a small group of low-level criminals were responsible for the murder, but that there was insufficient evidence to indict Dany Toussaint—findings that Dominique's widow Michèle Montas contested in an appellate court, demanding that the intellectual authors of the crime be found and punished. In December 2004, more than 75% of documents relating to the investigation disappeared from the Cour de Cassation (Haiti's Supreme Court). In addition, several suspects and witnesses died under mysterious circumstances. Most recently, in March 2015 Aristide's former chief of security Oriel Jean was gunned down by unknown assailants, after which journalist Guy Delva released an interview in which Jean suggested that Aristide had ordered Dominique's assassination. To date, the authors of the crime have never been brought to justice.
