A recent U.S. indictment claims that Miguel Angel Treviño Morales, also known as "Zeta 40," has maintained control over the Northeast Cartel from within a Mexican prison. Treviño Morales, a co-founder of the infamous Zetas cartel, has been incarcerated since his capture in 2013.
The indictment details how Treviño Morales and his brother Omar—who was arrested in 2015—established the Northeast Cartel as a successor to the Zetas. The brothers reportedly tasked relatives with managing the cartel's day-to-day operations while they remained behind bars. This situation raises serious concerns about security within Mexican prisons, where inmates can often meet with lawyers and family members without sufficient oversight, facilitating communication with the outside world.
