Diplomats say the death of Col. Jean-Claude Paul, a suspected drug trafficker who died after eating what police believe was poisoned pumpkin soup, may help ease tensions between the United States and Haiti.

Police Chief Georges Valcin said Monday that officers arrested Mireille Delinois, Paul's former wife, and two servants shortly after his death Sunday.Radio Haiti Inter quoted Valcin as saying the three were suspected of poisoning Paul's pumpkin soup. No motive was disclosed.

Paul, Delinois and Paul's brother, Antonio, were indicted in March by a federal grand jury in Miami on charges they smuggled more than 200 pounds of Colombian cocaine to the United States in 1986 through a landing strip at Paul's farm.
