D’Lani Sweeney joins NewsNation to discuss the disappearance of 20-year-old Sudiksha Konanki, a University of Pittsburgh student who vanished nearly five days ago while on spring break in Punta Cana, Dominican Republic. Konanki was last seen leaving a hotel bar with friends before heading to the beach. While most of the group later left, she stayed behind with a man — who eventually left without her. Sweeney, who was at the same resort that day, says the waves were dangerously high and has video evidence to support her claim.
