PORT-AU-PRINCE, Haiti — The commander in charge of guarding the Haitian president’s home quickly became a suspect in the assassination of President Jovenel Moïse last month when his security team inexplicably melted away, enabling hit men to enter the residence with little resistance and kill the president in his own bedroom.
But current and former officials say that the commander, Dimitri Hérard, was already a suspect in a separate case that the United States Drug Enforcement Administration has pursued for years: the disappearance of hundreds, if not thousands, of pounds of cocaine and heroin that were whisked away by corrupt officials only hours before law enforcement agents showed up to seize them.

Haitian officials, including the country’s prime minister, have acknowledged that the official explanation presented in the days after the assassination — that Mr. Moïse was gunned down in an elaborate plot to seize political office — does not entirely add up, and that the true motive behind the murder has not been uncovered.

“The port is an open sewer,” Mr. Greco said.
Van Williams, another United Nations anti-narcotics supervisor based in Haiti at the time, agreed.
“There was very little importance placed on the docks, which I found very strange,” Mr. Williams said. “Corruption in Haiti from the top on down is so rampant.”
