A federal court sentenced two individuals to prison for their roles in a large-scale cocaine trafficking operation that investigators tracked back to Mobile. Adan Ubaldo Sepulveda-Ruiz received a 25-year prison term, while Juan Ali Popoca-Flores was sentenced to 68 months.
Why it matters
The sentencing concludes an investigation into a significant cross-state drug operation that supplied the Mobile area with large quantities of cocaine. Authorities utilized a drug ledger to document the distribution of thousands of kilograms of the illegal substance.
Adan Ubaldo Sepulveda-Ruiz was sentenced to 25 years in prison, while Juan Ali Popoca-Flores received a 68-month term. Both defendants are subject to removal proceedings following the completion of their prison sentences.

FBI
The federal agency conducted the investigation that linked the drug operation in Mobile to the defendants arrested in Texas.
The details

The sentencing for the two defendants was announced on October 30, 2026.
Legal Context
The case follows the federal sentencing guidelines for continuing criminal enterprise and large-scale drug distribution offenses. It reflects the broader federal effort to dismantle high-volume drug networks operating across state lines.
The dismantling of this drug operation helps mitigate the flow of illegal narcotics into the local area. This prosecution reflects a continued emphasis by federal authorities on targeting the logistical supply chains that feed local drug distribution.
The takeaway
Large-scale drug operations often face disruption when law enforcement identifies the primary supply network following local arrests. Authorities emphasize that monitoring drug ledgers and financial proceeds remains a critical tactic in building cases against trafficking organizations.
