She happened to know him better than anyone else.Martine Moise, the first lady of Haiti, was found bleeding on the floor next to the body of her husband, Jovenel Moise, on July 7. But she survived the mysterious attack -- and is now lighting a fire under the search to bring the killers to justice.In an interview in South Florida on Sunday, Mrs. Moise -- still in mourning black, her arm bandaged from wrist to shoulder -- described chilling details of the attack to CNN and demanded the world's help in solving the murder."Someone gave the order, and someone paid the money. Those are the people that we are searching for. I want the United Nations Security Council's help to find those people," she said.Mrs. Moise is the only eyewitness to her husband's assassination. She is also the only other known victim, her elbow and forearm shattered in a hail of bullets as attackers entered the presidential suite.She first knew something was wrong that night when she and her husband heard automatic gunfire outside their home around 1 am. Once they realized that the gunmen had entered the house, they tried to hide on the floor behind their bed, she said.Even then, however, Moise did not believe what was about to happen."At that time, I didn't even think that they were going to be able to get into the room where we were, because we had about 30 or 50 security guards (at the house)," she said.Yet they did, in a massive security failing that Haitian authorities still have not explained. At least two top security chiefs are currently in prison, including presidential security chief Dimitri Herard and coordinator of palace security Jean Laguel Civil.
