University of Pittsburgh student Sudiksha Konanki, 20, disappeared on March 6, 2025, during a spring break trip to Punta Cana, Dominican Republic. She was last seen near the Riu República Hotel. 
Joshua Riibe, a 22-year-old student from Iowa, is a person of interest in the case. Riibe claims he and Konanki entered the ocean together, were caught by a strong wave, and he managed to rescue her back to knee-deep water. Afterward, he became ill and, upon recovering, noticed Konanki was missing.
Surveillance footage captured Konanki and Riibe walking toward the beach around 4:15 a.m. on March 6. Riibe was later seen returning alone around 8:55 a.m. 
Authorities have not ruled out foul play in Konanki’s disappearance.
