Moïse was killed on July 7, when armed men raided his private home. His wife, Martine Moïse, was seriously wounded but is recovering.
Police have detained more than 40 suspects, but there's still no clarity about who was behind the plot to kill him. Among the detainees are 18 former Colombian soldiers and 20 Haitian police officers.
Recently installed Prime Minister Ariel Henry had pledged to hold elections as soon as possible and said his government wanted a free and transparent vote.
The poorest country in the Western Hemisphere, Haiti has been struggling with political instability for decades. During his government, Moïse faced protests from people demanding he to step down while gang violence wracked parts of the country.
Political tensions increased in February when some opposition leaders claimed Moïse’s legal term had expired. Moïse argued his term ended in February 2022 since he wasn’t sworn in until 2017.
