The confiscation of an Iowa college student’s passport during an investigation in the Dominican Republic serves as a warning for Americans traveling overseas. An expert advises that travelers should be careful to safeguard their travel documents.

In the previous month, 22-year-old Joshua Riibe had his passport and cellphone taken by investigators trying to unravel the last known activities of missing spring breaker Sudiksha Konanki. Hotel security cameras showed that Riibe was one of the last people to interact with Konanki before she vanished from a Punta Cana beach following a night out with friends.

Following Konanki’s disappearance, Riibe was kept at the Riu Republica Hotel under the supervision of local officials, although authorities noted he was never considered a suspect.

Riibe, a student at St. Cloud State University in Minnesota, remained in the Dominican Republic, unable to travel back to America, for approximately two weeks before he was able to head home.

The family’s fight to bring Keith home, while also grappling with the death of Fitzsimons, led Gladdin down a path of teaching parents how to instill travel safety habits in their families. 

“Travel is one of the most eye-opening things we can do,” Gladdin said. “But help them make educated choices. I’m not against travel, but I’m for educated travel.” 

Gladdin also points parents toward federal resources aimed at keeping Americans safe while traveling abroad. The State Department’s Smart Traveler Enrollment Program provides vacationers with the opportunity to register their trips with the government, in the event something goes wrong. 

“[Officials] can quickly update and get in contact with you regarding any safety or security information – whether it’s like an impending cyclone or a terrorist threat – that they need to get you out of a country quickly, if they know you’re there,” Gladdin said. 

Fox News Digital reached out to the State Department for comment. 

Gladdin’s passion for travel safety and educating parents was born from tragedy, but she insists it does not have to be that way for other families. 

“Lying on the floor of my sister’s closet, choosing out her funeral dress rather than helping to choose her wedding dress – there are no positives in that,” Gladdin told Fox News Digital. “I think finding purpose in what you’re going through, [by] leaning towards problems that are surrounding you and [finding] what you can do to help solve them. My family created a purpose in Nicole’s death by looking at the problem of travel safety and doing whatever we could to solve it.”
