A cartel leader tied to Laredo will spend almost 19 years in prison. His name is Roberto Lopez. He is 46 years old. Agents also knew him by two names: "Shrek" and "NWA."

A federal court in Atlanta gave Lopez his sentence. The date was September 9, 2026. The judge gave him 18 years and 10 months in prison. After that, he must be watched by the government for five more years.

Lopez worked for a drug boss named Edgar Valdez Villarreal. Most people know Valdez by his nickname. They call him "La Barbie." In the early 2000s, Valdez was a top enforcer for two cartels: Sinaloa and Beltran-Leyva. He fought in a bloody drug war. The other side was the Gulf Cartel and the Zetas. Like Lopez, Valdez got his start in Laredo. He later built a huge drug network. A court sent Valdez to prison in 2018. He got 49 years.

Lopez was one of Valdez's top men. He ran the trucking and money side of the group. He paid truck drivers. He paid workers at stash houses. He packed up cash. He moved it across the border. Agents caught him on wiretaps. He talked about drug loads. He talked about cash runs.

The group moved a lot of drugs. It shipped up to 300 kilograms of cocaine every week. That is about 660 pounds. Some went to Atlanta. Some went to Memphis. In just six months, the group moved 1,500 kilograms of cocaine in Atlanta alone. That is more than 3,300 pounds.

The cash moved fast too. Each trip back to Mexico carried at least $1 million in cash.

The group also moved guns into Mexico. It sent more than 1,000 rifles. It sent 100 to 200 machine guns. Those guns had been changed to fire like military weapons. The group also sent ammo drums. It sent silencers. It sent night vision goggles. It sent body armor and helmets.

A grand jury charged Lopez back on December 15, 2009. He ran to Mexico once the case fell apart. He hid there for years. Mexican police finally caught him in Mexico City. That was June 27, 2024. Mexico sent him to the United States on August 12, 2025.

Lopez pleaded guilty on May 19, 2026. He admitted to a plot to sell cocaine. He also admitted to a plot to launder money. Money laundering means hiding where drug cash really comes from. It makes dirty money look clean.

Prosecutors say Lopez was a top lieutenant for a second man too, Carlos Montemayor. Montemayor ran a trucking business in the U.S. A court sentenced Montemayor in 2019. He got 34 years and three months.

U.S. Attorney Theodore Hertzberg talked about the case. He said Lopez was once "the head of domestic transportation" for cartels that "poured drugs into our community." He said his office will "never cease" efforts to catch cartel fugitives.

A DEA leader named Michael Connolly also spoke. He is the acting special agent in charge in Atlanta. He said the sentence shows what happens "when agencies work together."

The DEA led the case. The U.S. Marshals helped. So did a Justice Department office that handles cases overseas. Two federal lawyers tried the case in court: Garrett Bradford and Elizabeth Hathaway. A former U.S. Attorney named John Horn also worked the case.

Federal officials say this case is part of a bigger push. It is called the Homeland Security Task Force. Many federal agencies work together on it. Their goal is to catch cartel fugitives and stop drug networks that reach into the United States.

Lopez and Valdez both got their start in the same border city. This case has deep South Texas roots, even though the courtroom sat almost 900 miles away in Atlanta.
