SANTO DOMINGO, Dominican Republic (AP) — The father of a 20-year-old University of Pittsburgh student Sudiksha Konanki, who went missing in the popular Dominican Republic tourist town of Punta Cana while on spring break with friends, said he has asked authorities to widen their investigation.

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.
