As the search for a missing American college student who vanished off a beach in the Dominican Republic continues, a retired FBI special agent says investigators can learn lessons from past cases like Natalee Holloway.

“One mistake foreign authorities often make is relying too much on voluntary cooperation from persons of interest,” Jason Pack, a retired FBI supervisory special agent, told Fox News Digital.

“The FBI should be urging Dominican officials to immediately seize electronic devices, examine travel history, and conduct forensic analysis on locations where she was last seen,” Pack continued.

Pack, who is also a former leader of the FBI’s Child Abduction Rapid Deployment Team and an acting legal attaché, said the FBI can’t take over the investigation but will use diplomatic channels to push Dominican authorities to prioritize key investigative steps, provide forensic assistance, and coordinate intelligence-sharing that could uncover new leads.

Konanki was last seen on surveillance camera with five other people entering the beach at the Riu República Hotel in Punta Cana after 4:15 a.m. Thursday, the Dominican National Police said in a statement.

Surveillance video, obtained by Noticias SIN, captured the group striding towards the beach at the five-star resort. The footage is the last time authorities tracked Konanki before the Virginia resident disappeared.

Konanki’s disappearance has sparked widespread speculation about the events leading up to it, prompting law enforcement in both the Dominican Republic and the U.S. to investigate.

Since her daughter’s murder, Beth Holloway has been advocating on her behalf and said that the disappearance of Konanki, 20, should be a warning for travelers.

“I have created the full-circle safety plan for travelers and citizens of all ages to remind them to spend as much time planning the end of their outing as they do planning where to go, what to wear and who they are going with,” Holloway said.

While early reports suggested Konanki 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.

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.
