MEDELLÍN, COLOMBIA — Authorities identified the body found in Colombia as that of missing U.S. flight attendant Eric Fernando Gutiérrez Molina. The 32-year-old American Airlines flight attendant disappeared in Medellín, Colombia, during a layover after a night out with a fellow flight attendant Saturday evening.

Colombian authorities confirmed to the family that Gutiérrez Molina's body was found Friday in the northeast region of Colombia, his sister said. Federico Gutiérrez said a lifeless body had been found between the municipality of Jericó and Puente Iglesias, according to a social media post.

"There is a very high probability that it is this person. The lifeless body is being transported to legal medicine in Medellín for identification and recognition," Federico Gutiérrez, Mayor of Medellín, wrote in a social media post. "We express our solidarity to his family and friends. I have just personally delivered the painful news to his father, who is in Medellín."

Federico Gutiérrez said authorities suspected foul play and that officials had very clear leads on those responsible, according to a social media post. Manuel Villa said at a news conference that Gutiérrez Molina was in Colombia on business.

Gutiérrez Molina and a co-worker were in Itagüí, Colombia, according to the news conference. They left an establishment to go to a second location with others in Itagüí. Villa said the co-worker arrived back at her hotel disoriented, and Gutiérrez Molina had not been seen since then, according to the news conference.

Their investigation determined that Gutiérrez Molina and the woman encountered people with a history of committing theft who used scopolamine, an anti-nausea medication that can cause drowsiness and confusion, according to the news conference. Villa said the investigation continues.

Gutiérrez Molina was a U.S. citizen and resident of North Texas. The family said Gutiérrez Molina was born and raised in El Salvador before coming to the U.S. and becoming a citizen, according to a GoFundMe post.

"It is with profound sadness we share the passing of Fernando Gutierrez. Fernando's personality will always be remembered as a ball of sunshine as he entered and exited a room," according to a GoFundMe post. "He will always be remembered as a docile, charismatic, goofy man who always provided a helping hand."

American Airlines said it was heartbroken by the tragic passing of its colleague, according to an American Airlines statement. "Our thoughts and support are with his family, loved ones and colleagues during this difficult time, and we are doing all we can to assist Colombian law enforcement in its investigation," the company said in a statement.
