A fentanyl cook recently gave an interview in which he detailed how long he was trained for, the process to make the lethal drug and measures taken when cartels believe authorities are getting close to finding them.
In an interview with Mexican journalist Oscar Balderas, the cook, who was masked and kept his identity hidden, said he began drug dealing when he was 12. He was arrested for the first time two years later and, after getting out, was taken to Mexico City at age 17 to become a cook.
