The FBI is testing samples taken from a minibar at one of the hotels used by some of the nine American tourists who died of unclear causes in the Dominican Republican over the past 13 months, Dominican officials told CNN on Wednesday. The samples were taken from the Bahia Principe Hotel, and Ministry of Health communications director Carlos Suero said anytime a person dies in a hotel room, they test samples collected from the room's minibar, sink, and shower for bacteria. In several cases, families of the deceased say their loved one had a drink from the minibar before their death. Dominican officials are adamant these were isolated cases and there's no reason for worried people to cancel their vacations.
