- A Colombian official confirms the plane had no fuel
- An air traffic controller says she's received threats since the crash
"I can affirm with absolute certainty that, for my part, I did what was humanly possible and technically required to preserve the lives of these users of air transport," Yaneth Molina wrote in an email to fellow air traffic controllers. "Unfortunately, my efforts were unfruitful, because of the reasons that you all know."
Molina's email was published Thursday by CNN affiliate Cablenoticias
, and Carlos Llanos, president of the Colombian Association of Air Traffic Controllers, confirmed its authenticity to CNN.
The plane crashed Monday night near Medellin, Colombia, killing more than 70 people, including members of the Brazilian soccer team Chapecoense
Colombian authorities say they've confirmed the plane had no fuel when it crashed.
"We initiated a process of investigations to establish the motives as to why they had no fuel," said Freddy Bonilla, the Colombian Civil Aviation Authority's air safety secretary.
In a purported recording
of the conversation between Molina and the doomed charter flight, the plane's pilot can be heard saying that the aircraft is "in total electric failure and without fuel," according to two sources familiar with the investigation who heard audio recordings.
In her email, Molina thanked colleagues for their support. She also wrote that she'd received threats since the crash from "ignorant people who are unaffiliated with this profession."
