Haitian national police have arrested Mesac Damas, 33, who is wanted by police in the deaths of five children and their mother in Naples.
Mario Andresol, the head of the HNP, told The Miami Herald that Damas was arrested Monday morning in Tabarre, a community near Port-au-Prince airport.
Florida authorities were searching for Damas on Sunday, a day after his wife and their five young children were found dead in their home. Officials and the family of the husband believed he had traveled to Haiti. News reports said his car was found at Miami International Airport.
"People think that Haiti is a place that you can just run to and it is not. If we have information, we will act," Andresol said.
Never miss a local story.
Haiti's police force has been criticized in years past for being corrupt and inept. But in recent years, the United States, Canada and the United Nations have spent millions on training and equiping the police department.
"We are trying to build a strong police force here," Andresol said. "It is young, but we are working."
