University of Pittsburgh student Sudiksha Konanki went missing in the Dominican Republic after allegedly being swept away by a wave. The last person to see her, Joshua Riibe, claims he saved her from rough waters but lost sight of her when she went to retrieve her belongings.

Joshua Steven Riibe, 24, has been identified as the man seen hugging and walking hand-in-hand with the 20-year-old student just hours before she vanished in the Dominican Republic.

Joshua Riibe, a 24-year-old tourist from Iowa, has come under the spotlight, with investigators naming him a 'person of interest.'

An international search continued Friday for a University of Pittsburgh student who vanished while on a spring break trip to the Dominican Republican earlier this month. Sudiksha Konanki, 20, was last seen on March 6 with a group of friends heading to a beach in Punta Cana.

A person of interest has been named in the ongoing investigation into the disappearance of 20-year-old Sudiksha Konanki, a pre-med student at the University of Pittsburgh who went missing while vacationing with friends in the Dominican Republic.

Investigators are still searching for Sudiksha Konanki, a University of Pittsburgh student who went missing while on a spring break trip with her college friends in the Dominican Republic last week.
