17 charged in California fentanyl trafficking network following HSTF investigation

SAN DIEGO - During the first week of September, 17 alleged members of a San Diego-based fentanyl trafficking organization were charged in federal court with distributing large quantities of fentanyl throughout the city.

On Sept. 3, more than 200 federal, state and local law enforcement officials completed a coordinated takedown, arrested 13 defendants, and executed a search warrant in San Diego. Two defendants had prior arrests within the same week, and two are fugitives.

During this 10-month Homeland Security Task Force investigation, authorities seized more than 27 kilograms of fentanyl, preventing more than 13 million potentially lethal doses from being distributed in San Diego. Furthermore, agents seized more than 14.5 kilograms of cocaine, 0.6 kilograms of heroin, 0.8 kilograms of methamphetamine, and $49,000 in cash.

"This investigation has been a massive, life-saving success, but we are not satisfied yet," said Homeland Security Investigations acting Executive Associate Director John Condon. "The combined effort of the HSTF, HSI San Diego, along with state and local partners has prevented more deadly fentanyl from reaching our neighborhoods, but this work continues. We will carry on using the full strength of this partnership to disrupt and dismantle every drug trafficking organization within our borders."

Court documents state in November 2025, HSI San Diego and the San Diego County Sheriff's Department, as part of the Fentanyl Abatement and Suppression Team, began an investigation into a drug trafficking organization supplying fentanyl to multiple street-level dealers in San Diego. On Nov. 25 that year, agents seized 4.8 kilograms of fentanyl, 0.8 kilograms of methamphetamine, $10,042 in cash and arrested Fabian Iniguez Ontiveros. A search of Iniguez's cell phone revealed dozens of different fentanyl sub-distributors working for this drug trafficking organization.

Through various investigative methods, agents identified the organization's leader and seized drug ledgers showing the organization routinely sold an ounce of fentanyl for $600 to $700, even making up to $20,000 in one night of deliveries. After Iniguez's arrest, agents identified the new principal fentanyl distributor in the United States as Maricielo Ibarra Barrera.

During April and May 2026, investigators infiltrated the organization, participating in multiple fentanyl purchases coordinated by the organization and delivered by Ibarra. Investigators used months of surveillance operations to observe hundreds of instances when Ibarra drove from her residence to various locations around San Diego making multiple brief stops consistent with drug distribution.

From June through August 2026, investigators obtained federal wiretaps targeting cellphones the organization used. During that time, investigators intercepted dozens of calls and texts between members of the organization in the U.S. and Mexico, leading directly to several fentanyl seizures.

On Aug. 17, agents arrested Ibarra and executed a search warrant at her residence, where investigators discovered approximately 1.7 kilograms of fentanyl, 0.6 kilograms of heroin and $15,568 in cash. On Sept. 1, agents arrested two more members of the organization - Richard Alexander Arias Cruz and Juan Manuel Godinez - and seized 14.52 kilograms of cocaine and 20.28 kilograms of fentanyl.

Special agents and task force officers with HSI San Diego's Fentanyl Abatement and Suppression Team led this investigation. HSI San Diego's FAST is a multiagency task force comprising state, local and federal partners. First established in August 2022, FAST focuses on the disruption and dismantlement of criminal organizations that smuggle and distribute fentanyl within San Diego County. FAST targets fentanyl smuggling and distribution networks to counter the rising overdose rate and decrease the availability and accessibility of fentanyl.
