HSI San Diego, multiagency case sends trafficker to 19.5 years in prison for supplying weapons and ammunition to Sinaloa Cartel

SAN DIEGO — Keith Octavio Rodriguez Padilla, a prolific firearms trafficker, was sentenced in federal court Jan. 13, to 19.5 years in custody for his role in supplying weapons and tens of thousands of rounds of ammunition to the Sinaloa Cartel.

This case is part of a long-running investigation targeting the Valenzuela Transnational Criminal Organization (TCO), which was a significant component of the Sinaloa Cartel. Homeland Security Investigations (HSI) investigated this case with assistance from multiple federal, state and local law enforcement partners*.

“Today’s sentencing is a direct result of the hard work and collaboration between HSI and our law enforcement partners. This extensive investigation highlights our unwavering commitment to protecting our country and communities from the dangers of illegal firearms trafficking,” said Shawn Gibson, Special Agent in Charge of HSI San Diego. “We will continue to work tirelessly to ensure that the drug trafficking organizations are disrupted and held accountable.”

“Guns and ammunition smuggled into Mexico support cartels and empower drug traffickers,” said U.S. Attorney Tara McGrath. “This case continues to deal blow after blow to that infrastructure, sending a clear message: DOJ will prosecute every angle of cartel operations — from drug importation to money laundering to arms trafficking — to combat death and destruction on both sides of the border.”

The Valenzuela TCO was one of the largest importers of cocaine into the United States. The TCO sourced cocaine and other controlled substances (including fentanyl, heroin, methamphetamine, and marijuana) from South America and Mexico, transported the drugs to multiple locations along the U.S.-Mexico border using commercial trucking companies, smuggled the drugs into the country, and distributed them throughout the United States. The TCO then smuggled the bulk cash proceeds from its drug trafficking activities back to the TCO’s leadership in Mexico.

According to court records, throughout 2020, the Valenzuela TCO, including one of its leaders, Jorge Alberto Valenzuela Valenzuela, was engaged in violent conflict with another component of the Sinaloa Cartel led by Ivan Archivaldo Guzman-Salazar. During this conflict, Jorge’s brother and previous TCO leader, Gabriel Valenzuela-Valenzuela, was killed. This led the Valenzuela TCO to procure large quantities of firearms, ammunition, tactical gear, armored vehicles, and ballistic vests. A considerable number of these items were sourced from within the United States and clandestinely smuggled into Mexico, using numerous arms trafficking networks.

During the multi-year investigation, agents identified Keith Octavio Rodriguez Padilla as a firearms and ammunition trafficker and broker for the TCO. Rodriguez Padilla and his co-conspirators worked with high-ranking organization members to supply firearms to the TCO. These firearms ranged from .50 caliber rifles, submachine guns, and grenade launchers to assault style rifles (AK-47s, AR-15s, FN SCARs) and handguns. In addition to the weapons, Rodriguez Padilla and his co-conspirators supplied tens of thousands of rounds of ammunition to the TCO. Some of these weapons and ammunition were acquired in the United States, including from California, Arizona, and Nevada, and then smuggled through the Ports of Entry in San Diego and Arizona to Mexico.

For example, on Nov. 20, 2020, DEA and HSI agents initiated surveillance at a commercial truck yard being operated by the Valenzuela TCO in the Otay Mesa area of San Diego. Agents ultimately obtained a search warrant for this truck yard and during the search, seized approximately $3,078,880 in bulk U.S. currency, approximately 685 kilograms of cocaine, 24 kilograms of fentanyl, and a pickup truck with a trap gas tank the size of half the truck bed were discovered. The truck yard contained numerous tractors-trailers, along with numerous other vehicles. Inside one of the trailers, agents seized approximately 20,000 rounds of .50 caliber ammunition, along with approximately 427 ballistic plate carriers, approximately 1,000 rounds of .40 caliber ammunition, and approximately 104 magazines for .50 caliber ammunition. Agents learned that Rodriguez Padilla had purchased the .50 caliber ammunition on behalf of the TCO.

To date, this investigation has resulted in charges against 109 defendants and the seizure of approximately 2,000 kilograms of cocaine and fentanyl, more than $16 million in cash, and 21,000 rounds of ammunition.

“Weapons trafficking fuels drug-related violence,” said DEA Special Agent in Charge Brian Clark. “Money and greed are the foundation of the Sinaloa cartel business model and Padilla provided a lifeline by trafficking firearms. This sentence underscores our commitment to aggressively pursue the Sinaloa Cartel at every level, to include all facilitators who profit from drug-related violence. Strong relationships between law enforcement agencies have proven invaluable as we work together to save lives.”

“This multi-year investigation and lengthy federal prison sentence highlights the hard work, dedication, and cooperation of multiple law enforcement agencies to disrupt and dismantle violent transnational criminal organizations,” said FBI Acting Special Agent in Charge Travis Holland. “Today’s sentence serves as a reminder, we will continue to leverage the strength of federal, state, and local law enforcement to bring justice against the Cartels and individuals working on their behalf.”

“Mr. Padilla’s role in trafficking weapons and ammunition not only facilitated violence between cartel organizations, but also facilitated the endangerment of American citizens as these transnational criminal organizations bring dangerous and deadly drugs into the United States,” said Special Agent in Charge Tyler Hatcher, IRS Criminal Investigation, Los Angeles Field Office. “This sentencing demonstrates the result of well-coordinated investigations and the effectiveness of our partnered investigations. Protecting American citizens is the number one priority for every law enforcement organization, and IRS-CI is proud to be a partner in this investigation.”

This case is being prosecuted by Assistant U.S. Attorneys Matthew J. Sutton and Mikaela Weber.

This prosecution is part of an Organized Crime Drug Enforcement Task Forces Strike Force Initiative, which provides for the establishment of permanent multi-agency task force teams that work side-by-side in the same location. This co-located model enables agents from different agencies to collaborate on intelligence-driven, multi-jurisdictional operations to disrupt and dismantle the most significant drug traffickers, money launderers, gangs, and transnational criminal organizations.
