The mayor of Colombia says that a body has been found in the search for an employee of the missing American Airlines flight

A body was found during the search for an American Airlines flight attendant who disappeared while sleeping in Medellin, Colombia, said the city’s mayor on Friday.

Eric Fernando Gutierrez Molina, 32, a US citizen and resident of North Texas, went missing Saturday evening after spending time with a co-worker on the plane. The two flight attendants visited a bar in the Medellin neighborhood of El Poblado, which is popular with foreign tourists, according to family and friends and Colombian officials.

Gutierrez Molina was to work on a flight from Medellin to Miami on Sunday. His longtime partner, Ernesto Carranza, told CBS News that he he was worried when he could not find her on Sunday morning.

Fico Gutierrez, the mayor of Medellin, said on Friday that a “lifeless body” was found between the municipalities of Jerico and Puente Iglesias during the search for Gutierrez Molina.

“There are many chances that it is this person,” he said in a social media post, adding that the body is being taken to the coroner’s office in Medellin for identification. “We express our solidarity with his family and friends. I have just conveyed the sad news to his father, who is in Medellin.”

Fico Gutierrez said the investigation is ongoing. Additional details were not immediately available.

In an internal report sent to American Airlines employees on Saturday, the airline said it was “heartbreaking to share the news” of Gutierrez Molina’s death, although there was no word on whether it had received confirmation from Colombian authorities that the body found was his. The airline said it was “engaged” with Colombian authorities as the investigation continued.

“We are doing everything we can to support his family as they mourn the loss of their son and brother and bring them back home to be placed in their final resting place,” said the airline. “Our thoughts are with his colleague, his loved ones, and the entire flight crew at this very difficult time.”

Carranza told CBS News that, after not being able to find him, Gutierrez Molina’s phone was seen ringing in two locations in Medellin that were not near his hotel.

“Both of these places were not close to where he was supposed to sleep,” Carranza said.

Adding to the mystery is that another flight attendant who went out with Gutierrez Molina on Saturday said she doesn’t remember parts of the night, her friend, Sharom Gil, told CBS News.

In a statement provided to CBS News Texas, American Airlines said it is “cooperating closely with local law enforcement officials in their investigation and we are doing everything we can to support the family of our crew member at this time.”

When reached by CBS News Texas, the U.S. Embassy in Colombia said it was “restricted from speaking about multiple cases due to federal privacy laws.”

The State Department also said in a statement to CBS News Texas that it is “aware” of “reports” of Gutierrez Molina’s disappearance and is “closely monitoring the situation.”

“The Trump administration has no higher priority than the safety and security of the American people, and the State Department stands ready to provide all diplomatic assistance to Americans in need abroad,” the State Department said Thursday.
