Investigators are continuing the search for a college student from Virginia who vanished earlier this month while visiting the Dominican Republic.

Police in the Dominican Republic say the FBI has joined the search for a 20-year-old University of Pittsburgh student who went missing nearly a week ago while on spring break.

At least 250 people, including small children, were seen waiting under the sun for hours, and in some cases, having to sleep two or three nights outside an Orlando Immigration and Customs Enforcement office.
