The Loudoun County Sheriff's Office in Virginia said an individual is considered a person of interest by U.S. investigators in the case and was interviewed at length.

A 'person of interest' has been named — but no charges have been filed — amid the search for missing college student Sudiksha Konanki, 20, who vanished during a spring break trip to the Dominican Republic.

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 in the Dominican Republic tourist town of Punta Cana, police said Tuesday.
