United States Drug Enforcement Administration

SACRAMENTO, Calif. —Jamaine Dontae Barnes, 42, of Stockton, pleaded guilty on Tuesday to running a continuing criminal enterprise, multiple counts of manufacturing and distributing pills laced with fentanyl, methamphetamine, and other drugs, illegal firearms possession, and international money laundering, U.S. Attorney Phillip A. Talbert and Drug Enforcement Administration Acting Special Agent in Charge Bob P. Beris announced. 

One of Barnes’ subordinates, Kavieo Daeshaun Lee Wiley, 28, of Stockton, also pleaded guilty Tuesday to conspiracy to distribute fentanyl, methamphetamine, heroin, and U-47700 (a synthetic opioid), and possession of a firearm in furtherance of drug trafficking.

According to court documents, from at least September 2015 through May 2019, Barnes led a Stockton-based pill-trafficking operation that regularly made and sold thousands of drug-laced pills. Barnes and his subordinates made the pills using pill presses, which are machines that compress powders into pills of various shapes and sizes. Barnes made pills that appeared to be legitimate prescription pills but in fact contained fentanyl, furanyl fentanyl, heroin, and other synthetic opioids that Barnes mixed into them. Barnes also made pills that appeared to be traditional Ecstasy pills, but in fact contained methamphetamine and other illegal stimulants. For years, Barnes obtained pill pressing equipment, materials, and illegal drugs from China, and at his direction, his subordinates made illegal international money transfers to purchase these materials.

In April and May 2019, investigators obtained a court-authorization for a federal wiretap and intercepted communications over Barnes cellphone. During this wiretap investigation, law enforcement seized thousands of methamphetamine-laced pills. On May 16, 2019, during search warrants executed at multiple locations across Stockton that Barnes and his subordinates used to manufacture, store, and distribute pills, investigators seized two pill press machines and other pill manufacturing equipment and materials; thousands of fentanyl-laced and methamphetamine-laced pills; powders containing fentanyl, methamphetamine, and other illegal drugs; and three firearms possessed by Barnes.

This case is the product of an investigation by the Drug Enforcement Administration, with assistance from Homeland Security Investigations, the U.S. Marshals Service, the U.S. Postal Inspection Service, the Bureau of Alcohol, Tobacco, Firearms and Explosives, the California Highway Patrol, the San Joaquin METRO Narcotics Task Force, the Tri-County Drug Enforcement Team (TRIDENT) Task Force, the Stockton Police Department, the Sacramento County High Intensity Drug Trafficking Area (HIDTA) Task Force, and the San Joaquin County Sheriff’s Office. Assistant U.S. Attorneys David W. Spencer and Emily G. Sauvageau are prosecuting the case.
