Missing American in Dominican Republic: Unpredictable ocean currents, beachfront pose major search challenge

PUNTA CANA, Dominican Republic — Unpredictable currents are known to impact the idyllic resort where University of Pittsburgh student Sudiksha Konanki was last seen before vanishing in the Dominican Republic last week.

Her last known whereabouts came in the early hours of March 6, as she was captured on hotel surveillance camera headed to the beach at the five-star Riu Republica resort in Punta Cana.

Everyone else seen going to the beach with her is accounted for. She never returned.

The resort has been flying red flags for days — indicating strong currents and big waves.

Even when the green flag is up — safe waters — conditions can change without warning, according to Yuri, a local charter boat captain.

"In the Caribbean, all of a sudden the wind comes," he told Fox News Digital. "You have to always be vigilant."

Many of the beaches have netting installed to keep swimmers safe and keep out floating seagrass. However, portions of the beach are unprotected, including several sections of the beach behind the Riu.

There is also a coral reef stretching along the Punta Cana beach that ends near the hotel’s beachfront, allowing for stronger currents, Yuri said. Sharks are uncommon in the area, but not unheard of, he added. In the daytime, they are likely afraid of the sound of motorboats. But the boats aren’t active at night.

The currents are also unpredictable, experts say.

"Punta Cana is located on the Mona Passage, which connects the Caribbean Sea and the Atlantic Ocean between the Dominican Republic and Puerto Rico," explained FOX Weather meteorologist and digital content producer Andrew Wulfeck, who examined coastal records from around the time of Konanki’s disappearance. 

"As is common where two waterways meet, the swell can be erratic and difficult to forecast, unlike the more predictable patterns often seen on beaches along the U.S. East Coast."

Because of the predictability of the coastline of the mainland U.S, he said, authorities know that if someone is washed away, they will typically be carried to the north.

"Unfortunately for authorities on the island of Hispaniola, the erratic nature of the swells there means it is impossible to predict where items may wash up, necessitating the need for heightened vigilance from all beachgoers," Wulfeck said.

In January, four tourists drowned near Punta Cana, when a red flag warned of strong currents and rough seas.

On the morning of Konanki’s disappearance, swells of between 4 and 6 feet were coming from the north and east, he said. However, in the following days, they shifted toward the east and south.

"Let's say, for instance, she was caught up in a rip current, she could have been dragged out and then the current could have carried her somewhere else," he said. "A nearby buoy in the Mona Passage indicates water temperatures are in the low to mid-80s, which can help support a person who might be stranded on a flotation device without the threat of immediate hypothermia."

While early reports suggested she may have drowned, experts say they believe she would have washed ashore or been found by now if that were the case. Authorities are officially urging the public not to jump to conclusions as the investigation unfolds.

They have identified and questioned a person of interest in the case, an American college student who was the last person seen with Konanki the morning she vanished, but it has not been deemed a criminal matter. It is currently a missing person investigation.

Konanki, a junior at the University of Pittsburgh who is from Loudoun County, Virginia, was last seen on security footage walking toward the beach around 4:15 a.m. She was with a group of young people, including five female friends and two young men, one of whom is believed to be a person of interest in the case. They had been drinking at the hotel bar.

The classmates and another man were seen returning to the hotel around 6 a.m.

Hours later another man, believed to be the person of interest, returned alone. Konanki has not been seen again.

Her friends reported her missing around 4 p.m.

Police have spent days searching the coastline with boats, dive teams and helicopters. The FBI is involved, and the sheriff from her Virginia hometown said he would be sending two detectives to assist in the investigation.

Rep. Suhas Subramanyam (D-Va.) told Fox News Digital that he spoke with Konanki's parents after their daughter disappeared.

"I just want to make sure it's a thorough investigation and that we use all the resources that we have at our disposal to bring her home safely," he said.

"I'm a dad and I have two daughters. This is every parent's worst nightmare," he said. "This is a very difficult time, not just for the family, but for the entire community."

"It's a very close-knit community here in Loudoun County."

The representative said that he advocated on behalf of Konanki's parents after the 20-year-old pre-medical student vanished on March 6.

"When I first found out that she was missing, we reached out to the embassies – here and in the D.R. We also reached out to the FBI and asked them to join in the investigation, which they did," he said. "We also worked with our local law enforcement to reach out to Interpol, and they engaged as well."

"We asked for resources, and we've gotten them," he said. "That has been encouraging, and I'm hopeful that all of these resources, and with the attention of high-level people, will lead to a resolution. We're praying every day."
