Carlos Montemayor González, also known as “El Licenciado,” “The Director” and “Fox,” was a Mexican organized-crime figure who became a senior member of a cocaine-trafficking network associated with the Sinaloa and Beltrán-Leyva cartels. U.S. authorities identified him as a key partner of Edgar Valdez Villarreal, known as “La Barbie.”
According to the U.S. Department of Justice, Montemayor operated a legitimate trucking and logistics company in Laredo, Texas, before becoming involved with Valdez Villarreal. Prosecutors said the transportation network was subsequently used to move cocaine from Mexico into the United States and to transport drug proceeds in the opposite direction.
Montemayor's relationship with Valdez Villarreal became particularly important after Valdez emerged as a senior figure within the Sinaloa and Beltrán-Leyva organizations. A 2015 U.S. Justice Department announcement described both men as alleged high-level members of the two organizations and said they had been charged in Georgia with conspiracy to import and distribute cocaine and conspiracy to launder money.
The investigation eventually reached the United States through a federal case centered in Atlanta. Prosecutors said Montemayor's transportation network had been used to distribute cocaine in several American cities. The investigation involved intercepted communications and seizures that helped federal agents establish the structure of the organization, according to the Justice Department.
Montemayor and Valdez Villarreal were arrested in Mexico in 2010. After several years in Mexican custody, both were extradited to the United States in September 2015 to face the federal charges filed against them.
Unlike some criminal figures whose profiles remain based primarily on allegations, Montemayor's U.S. case resulted in a guilty plea. On November 14, 2018, he pleaded guilty to conspiracy to import cocaine, conspiracy to distribute cocaine, possession with intent to distribute cocaine and conspiracy to launder money.
On September 24, 2019, a federal judge in Atlanta sentenced Montemayor to 34 years and three months in prison, followed by ten years of supervised release. The sentence resulted from his guilty pleas to the federal drug-trafficking and money-laundering offenses.
The case also established his connection with Edgar Valdez Villarreal. The Justice Department described Montemayor as the head of the U.S. arm of Valdez's cocaine transportation and distribution network. Valdez himself was later sentenced in 2018 to 49 years and one month in federal prison after pleading guilty to federal drug-trafficking and money-laundering offenses.
Montemayor's story illustrates how legitimate commercial infrastructure can become entangled with international organized crime. His trucking operation initially served ordinary cross-border commerce, but according to the evidence presented by U.S. prosecutors, it later became part of a much larger trafficking network.
For legal accuracy, Montemayor should not simply be described as an “accused” trafficker. His status in the principal U.S. case is that of a convicted defendant who pleaded guilty to federal cocaine-trafficking and money-laundering offenses and received a lengthy prison sentence.
His case remains connected to the broader history of the Sinaloa and Beltrán-Leyva organizations and to the rise of Edgar Valdez Villarreal as one of the most prominent American-born figures within Mexico's organized-crime landscape.
