Nine American tourists have died in the last year in the Dominican Republic

A New Jersey man has become at least the ninth US tourist to die in the Dominican Republic in a string of deaths the FBI is investigating.

Relatives of Joseph Allen, 55, say he was healthy and had been a frequent visitor to the Caribbean island nation.

Several of the tourists who died over the past year drank from their hotel minibar before falling ill, say family.

The FBI is helping local authorities with toxicology tests. No link has been established between the deaths.
