The FBI has now closed its investigation into two suspicious bottles that shutdown Tri-State airport last week.
A FBI spokesperson says additional tests found only water and soap in both bottles. At first, bomb sniffing dogs detected a trace of explosives, but investigations say further tests found nothing dangerous.
The passenger carrying them was Rima Qayyum of Barboursville.
She was detained and interviewed by the FBI for several hours last Thursday, but never charged with a crime.
The next day she drove to see her parents in Michigan.
