The boyfriend of a missing American Airlines flight attendant who vanished during a Colombia layover says he is “shattered” by the disappearance, as officials confirm there are suspects in his case.

Eric Fernando Gutiérrez Molina, a 32-year-old Dallas–Fort Worth–based crew member, was last seen in Medellín, Colombia, after arriving on a flight from Miami for an overnight stop, according to officials. He was scheduled to return to the U.S. the following day but never reported for duty, raising immediate alarm among colleagues and loved ones.

Friends and investigators say Gutiérrez Molina went out Saturday night in the popular El Poblado nightlife district with coworkers. At some point, he met two men at a club, and the group decided to continue socializing elsewhere. He later sent a message sharing his location at an Airbnb, but all communication stopped shortly afterward, which loved ones say is unlike him.

“I want to believe that he’s alive, and I want to continue believing that he’s alive, but throughout each day you wake up not knowing anything, and it makes the days go by longer and slower,” Ernesto Carranza, Gutierrez Molina’s longtime partner, told CBS News Thursday.

Sharom Gil, Gutiérrez Molina’s best friend, added, “I’m missing a part of me … He’s the most joyful person to ever to be around. We’re so lost right now.”

One of Gutiérrez Molina’s coworkers was later found disoriented and required medical attention. Family members and friends now fear Gutiérrez may have been drugged, possibly with scopolamine, often referred to as “devil’s breath,” a substance known to cause confusion, memory loss, impaired judgment, and even unconsciousness.

Authorities in Colombia have identified multiple suspects who may be connected not only to Gutiérrez’s disappearance but also to similar robberies involving the drug, CBS reported.

Missing persons reports have been filed in both the U.S. and Colombia, and the U.S. Embassy has been notified. American Airlines said it is working closely with authorities and supporting the flight attendant’s family as the investigation continues.

Officials say the search remains active, with local law enforcement and international agencies working to trace phone data, surveillance footage and witness accounts.

The disappearance comes as a U.S. State Department travel advisory for Colombia remains in effect, urging Americans to “reconsider travel” amid ongoing concerns over widespread violent crime.

Anyone with information on Gutiérrez Molina’s whereabouts is asked to contact the police.
