Phoenix, AZ – A routine Arizona Department of Public Safety (AZDPS) inspection turned into a major drug bust after troopers discovered 233 pounds of cocaine hidden inside a semi-trailer traveling along Interstate 17 on October 24, 2025. Authorities say the seizure marks one of the largest narcotics interceptions in the state this year.
The Incident: Cocaine Hidden Inside Semi-Trailer
According to the Arizona Department of Public Safety, Canine District troopers conducted a commercial vehicle inspection on a semi-trailer during a highway patrol stop on Interstate 17 north of Phoenix.
During the inspection, a K-9 unit alerted to the presence of narcotics, prompting officers to search the vehicle more thoroughly. They discovered an aftermarket compartment built into the trailer that contained 233 pounds of cocaine.
Officials estimate the street value of the seized drugs at approximately $3 million. The troopers immediately detained the driver, who was later booked on multiple felony charges, including possession and transportation of a narcotic drug for sale.
Investigation and Evidence Collected
Investigators believe the cocaine was being transported from California to New Jersey as part of a larger interstate trafficking operation. Authorities say the driver was acting as a courier for an organized drug network moving shipments across multiple states.
“This seizure reflects the vigilance and determination of our troopers in disrupting drug trafficking operations and protecting our communities from the spread of dangerous drugs,” the AZDPS said in an official statement.
The discovery of a custom-built compartment inside the trailer indicated a sophisticated concealment method, designed to avoid detection during inspections. Forensic teams have since taken custody of the evidence, and federal agencies are expected to assist in tracing the cocaine’s origin and intended recipients.
Court Proceedings and Charges Filed
The suspect’s name has not yet been released pending further investigation. Authorities confirmed that the driver faces several Class 2 felony charges under Arizona law, which could carry decades in prison if convicted.
In Arizona, possession of more than nine grams of cocaine for sale is considered an aggravated felony, and federal prosecutors may also pursue interstate trafficking charges due to the drugs’ intended cross-country route.
The Maricopa County Attorney’s Office is reviewing the case and coordinating with the Drug Enforcement Administration (DEA) to determine whether additional suspects will be charged.
Statements and Law Enforcement Response
Officials praised the troopers’ quick response and attention to detail during the inspection.
“Our troopers are on the front lines every day, monitoring Arizona’s major corridors for criminal activity,” an AZDPS spokesperson said. “This arrest sends a clear message — those transporting narcotics through our state will be caught and prosecuted.”
The AZDPS has been increasing drug interdiction patrols along Interstates 10, 17, and 40, routes frequently used by traffickers moving shipments between the West Coast and the East Coast.
According to state records, Arizona highways have seen a 40% increase in narcotics seizures in 2025 compared to the previous year.
Background and Broader Context
Arizona remains a major transit corridor for drug trafficking networks operating between California, Mexico, and eastern states. The state’s proximity to border crossings and access to major interstate highways makes it a critical passage point for large shipments of cocaine, fentanyl, and methamphetamine.
Authorities have emphasized that highway drug seizures not only disrupt criminal organizations but also prevent thousands of doses from reaching communities across the country.
The AZDPS continues to collaborate with the DEA, Homeland Security Investigations (HSI), and local police departments to share intelligence and intercept trafficking routes.
Ongoing Developments and Next Steps
The investigation into the interstate cocaine shipment remains ongoing. Detectives are working to identify additional individuals and organizations linked to the transportation route. The seized drugs have been sent for laboratory analysis, and officials expect further arrests as the probe expands.
Authorities said the incident underscores their ongoing commitment to combat large-scale narcotics smuggling through Arizona’s major transport networks.
Conclusion
The 233-pound cocaine seizure on I-17 highlights the crucial role of vigilant troopers in disrupting cross-country drug networks. With an estimated street value of $3 million, the bust stands as a major victory in Arizona’s fight against organized narcotics trafficking.
