Authorities are searching in the tourist town of Punta Cana for any signs of 20-year-old Pitt student Sudiksha Konanki, who disappeared while on spring break.

The search for a missing University of Pittsburgh student who disappeared last week while on a spring break trip to the Dominican Republic entered its fourth day on Monday. Authorities are searching by land,

Dominican officials involved in the investigation told ABC News Sunday that Konaki likely died by drowning after jumping in the ocean, but her father, Subbarayudu Konanki, suspects his daughter may have been abducted. Her body has yet to be discovered.
