The FBI is working with Dominican authorities in the investigation of recent tourist deaths, according to the US Embassy in the Dominican Republic.
The FBI is assisting in further toxicology analysis of the deaths that took place at the Bahia Principe in La Romana. The agency said the results could take up to a month.
The Embassy in Santo Domingo said in a statement last week that the two governments are working together to ensure that US travelers are safe.
"The safety and security of US citizens that live in, work in, and visit the Dominican Republic remains our highest priority. These incidents are tragic and we offer our deepest condolences to those personally impacted," Ambassador Robin Bernstein said according to the statement.
Officials ask that the public be patient as the investigations unfold.
