SAN ANTONIO - High-ranking drug cartel kingpin for Los Zetas was sentenced to seven consecutive life imprisonment sentences on Wednesday.

A federal judge sentenced 34-year-old Marciano Millan-Vasquez to seven consecutive life imprisonment sentences for committing and aiding and abetting the commission of numerous murders and other acts of violence, drug trafficking and weapons trafficking in Northern Mexico in furtherance of a drug distribution operation.

“Without mercy or compunction he brutally murdered anyone and everyone as it suited him and his cartel, at times inflicting the cruelest of pain, forcing relatives to watch their loved ones murdered before he turned his blades on them,” stated United States Attorney Richard L. Durbin, Jr. “Today’s sentence marks an end to his reign of terror over the drug plaza in Piedras Negras.”

During a three-week trial in July 2016, Millan-Vasquez, known as "Chano," who controlled the region of Piedras Negras for Los Zetas was found guilty on all charges including killing while engaged in drug trafficking; conspiracy to distribute and import marijuana; distribution of controlled substances outside the U.S. intending that they be imported into the U.S.; employing minors in a drug crime; conspiracy to distribute cocaine; conspiracy to distribute methamphetamine; conspiracy to possess firearms in furtherance of a drug trafficking crime; and, making a false statement to a federal official.

During that trial, former Zetas members testified that the cartel was responsible for a bloody massacre in Piedras Negras in 2011.
