Atlanta, GA – Roberto Lopez, an alleged lieutenant for the Sinaloa and Beltran-Leyva Cartels known by aliases including “Shrek,” “La Barbie,” and “NWA,” was extradited from Mexico and detained in Atlanta this week to face federal charges. Officials say Lopez ran a large cocaine-smuggling network, supplied weapons to cartel enforcers, and moved millions in cash across the U.S.-Mexico border.
The arrest and arraignment mark a major step in a long-running investigation into transnational trafficking that federal prosecutors say funneled drugs and weapons through U.S. cities including Atlanta and Memphis. Lopez pleaded not guilty and was detained by a U.S. magistrate judge pending further proceedings.
How ‘Shrek’ Was Captured and Extradited
Lopez, who had reportedly been hiding in Mexico for over a decade, was located, detained, and extradited to the United States to face charges that include cocaine importation, distribution, and money laundering. He was arraigned in federal court on Friday and remains in custody after being detained by U.S. Magistrate Judge Linda T. Walker.
Alleged Crimes and Federal Charges
Federal prosecutors describe Lopez as a logistics and arms supplier for high-level cartel leaders. The formal allegations include:
- Conspiracy to import and distribute cocaine — counts that carry a potential statutory maximum of life imprisonment for each drug count.
- Money laundering — a charge that carries up to 20 years in prison.
- Smuggling weapons — accused of moving hundreds of machine guns, assault weapons and more than 1,000 rifles into Mexico from the United States.
Role in Cartel Operations
According to authorities, Lopez served as the chief armorer and transportation head for enforcers such as Edgar Valdez-Villareal (aka “La Barbie”) and partnered operators including Carlos Montemayor. Prosecutors say the network moved as much as 300 kilograms of cocaine per week to U.S. cities, while coordinating large cash flows back to Mexico.
Investigators allege Lopez also handled operational logistics — paying truck drivers and stash-house operators, repackaging and transporting cash, and providing weapons and equipment that prosecutors say helped fuel cartel violence.
Reactions from Federal Authorities
“Lopez allegedly moved tons of cocaine and millions of dollars through Atlanta and other cities while supplying machine guns and other tools of war to fuel cartel bloodshed in Mexico,” said U.S. Attorney Theodore S. Hertzberg.
“This violent cartel member is part of a ruthless criminal network that profits from drugs, guns, and bloodshed,” said Robert J. Murphy, Special Agent in Charge of the DEA Atlanta Division.
Evidence and Notable Allegations
Officials have tied Lopez to several specific activities:
- Management of a vast cocaine smuggling network serving cities in the U.S.
- Procurement and smuggling of weapons and tactical gear into Mexico.
- Alleged involvement in distributing a video of an assassination of a cartel rival.
What Happens Next?
Lopez has pleaded not guilty. Federal prosecutors will continue preparing for trial, and the defendant remains detained. If convicted on the major counts, Lopez faces severe penalties including potential life sentences on drug charges plus additional time for money laundering.
Authorities say the case remains part of broader efforts to dismantle transnational trafficking networks that use U.S. infrastructure to move drugs, cash, and weapons.
