Authorities in Virginia have identified a person of interest in connection to University of Pittsburgh student Sudiksha Konanki’s mysterious disappearance last week in the Dominican Republic.

Iowa resident Joshua Riibe “has been interviewed at length,” Thomas Julia, a spokesperson for the sheriff’s office in Loudoun County, where the missing college student is from, told Fox News Digital.

However, Riibe has not been accused of foul play in what is “still a missing person case, not a criminal case,” the sheriff’s spokesperson stressed.

“Sheriff [Michael] Chapman wants to make sure the investigation is comprehensive and includes all possible assets and techniques,” Julia said.

“We are working closely with the FBI on all of this, and they are working with the Dominican National Police.”

Riibe was seen with the still-missing student on surveillance footage as they walked with friends toward the beach area around 4:15 a.m. Thursday, according to the Dominican Republic National Police. 

Footage obtained by Noticias SIN showed Konanki seemingly clinging to Riibe, a fellow guest at the Caribbean resort, as the group walked onto the beach. 

Konanki and several friends were on the beach before most of the group called it a night and headed back to their hotel, leaving the young woman on the sand along with her male companion, according to Dominican media. 

Riibe is a former wrestler and football player at Central Lyon High School in Rock Rapids, Iowa, and a senior at St. Cloud State University in Minnesota, his LinkedIn bio states. Fox News reported he was 24, but online records suggest he is 22.

He traveled to the Dominican Republic for his spring break trip.

Police did not make clear if Riibe and Konanki knew each other before meeting on the Caribbean Island.

Konanki, a 20-year-old pre-med student, was on spring break with five friends at the Riu Republic Resort in Punta Cana on March 6 when she vanished. She was last seen on the beach and Riibeis believed to be the last person to see her alive.

Riibe gave authorities three different accounts of what happened after the two were alone on the beach, first telling cops he threw up from the rough surf and went back to shore – but asked Konanki if she was OK, according to local reports. 

In the second version, he allegedly said he felt sick to his stomach and left the water, at which point he last saw the missing woman in knee-deep surf before he passed out.

He then told authorities he saw the Indian citizen and permanent US resident walking along the shore before he passed out on the sand. 

Dominican police have not said if they suspect foul play, but said Riibe is cooperating with their investigation. 

Local authorities have speculated that the spring breaker from Chantilly, Virginia, likely drowned after jumping into the ocean.

Her father, Subbarayudu Konanki, called on authorities Monday to expand search efforts over his “growing suspicion” that she was kidnapped, since her body never washed ashore. 

Police in Punta Cana said Tuesday they are reinterviewing Konaki’s five travel companions, hotel employees and others who were with her in the early hours at the ritzy resort. 

The investigation is being led by a “high-level commission” of local and US agencies, including the FBI, officials said. 

The search entered its fifth day Tuesday, with missing person posters describing the young woman as 5 feet 3 with black hair and brown eyes.
