Lieutenant in Sinaloa and Beltran-Leyva Cartels Detained in Atlanta After Years of Hiding in Mexico

ATLANTA - Roberto Lopez, a/k/a Shrek, a/k/a NWA, was arraigned and detained in federal court on Friday following his transfer from Mexico to face federal charges of cocaine importation and distribution and money laundering. Lopez, who was hiding in Mexico for more than a decade before his capture, allegedly smuggled hundreds of machineguns and assault weapons and helped manage a vast cocaine smuggling network in support of high-level cartel leaders.

“Lopez allegedly moved tons of cocaine and millions of dollars through Atlanta and other cities while supplying machineguns and other tools of war to fuel cartel bloodshed in Mexico,” said U.S. Attorney Theodore S. Hertzberg. “Though it took years to find and arrest him, he will now finally be held accountable for his crimes.”

“This violent cartel member is part of a ruthless criminal network that profits from drugs, guns, and bloodshed,” said Robert J. Murphy, the Special Agent in Charge of the DEA Atlanta Division. “DEA will not stop until every member of these organizations is taken off of our streets.”

According to U.S. Attorney Hertzberg, the charges, and other information presented in court: In the early 2000s, Edgar Valdez-Villareal, a/k/a “La Barbie,” was an infamous and ruthless enforcer for the Sinaloa and Beltran-Leyva Cartels in their war against the Gulf Cartel and the Zetas. Valdez also partnered with U.S.-based trucking businessman Carlos Montemayor to operate a distribution network that moved up to 300 kilograms of cocaine per week to Atlanta, Memphis, and other cities while smuggling cash back to Mexico in shipments carrying no less than $1 million per load. In just a six-month period, the organization distributed 1,500 kilograms of cocaine in Atlanta alone.

In 2018, a federal judge in Atlanta sentenced Valdez to 49 years and one month in prison to be followed by 10 years of supervised release. In 2019, Montemayor was sentenced to 34 years and three months in prison to be followed by 10 years of supervised release.

Lopez is alleged to have been the primary lieutenant for Valdez and Montemayor’s network, handling various logistics, including payments to truck drivers and stash house operators and the repackaging and transportation of money over the border. Lopez is also alleged to have been in charge of supplying weapons and other equipment to the cartels, obtaining high-powered rifles, silencers, ammunition, magazines, night vision goggles, ballistic vests, helmets, and other gear in the United States and smuggling them into Mexico. He also allegedly developed skills to convert semiautomatic rifles to function as fully automatic machineguns and manufactured silencers for handguns. He is estimated to have smuggled over 1,000 rifles, 100-200 converted machineguns, and over 1,000 magazines and ammunition drums into Mexico from the United States. As part of the cartel’s intimidation campaign and reign of terror, Lopez is also alleged to have played a critical role in distributing a video of the assassination of one of Valdez’s rivals to media and law enforcement in the United States and Mexico.

U.S. Magistrate Judge Linda T. Walker detained Lopez, 45, of Texas, on Friday after he pled not guilty to charges of conspiring to import, possess with intent to distribute, and distribute cocaine; possessing cocaine with intent to distribute; distributing cocaine; and conspiring to commit money laundering. A federal grand jury indicted Lopez for those crimes on December 15, 2009, nearly 16 years ago. Lopez faces a statutory maximum of life imprisonment for each of the drug counts and up to 20 years of imprisonment for the money laundering count.

In determining the actual sentence, the Court will consider the United States Sentencing Guidelines, which are not binding but provide appropriate sentencing ranges for most offenders.

Members of the public are reminded that the indictment only contains charges. The defendant is presumed innocent of the charges, and it will be the government’s burden to prove the defendant’s guilt beyond a reasonable doubt at trial.
