SACRAMENTO, Calif. —Jamar Deontae Barnes, 43, of Stockton, was sentenced today by U.S. District Judge Dale A. Drozd to 16 years and eight months in prison for conspiracy to manufacture and distribute pills laced with fentanyl, methamphetamine, and other drugs, and possession with intent to distribute methamphetamine-laced pills, Acting U.S. Attorney Michele Beckwith and Drug Enforcement Administration Special Agent in Charge Bob P. Beris announced. 

According to court documents, from at least September 2015 through May 2019, Barnes conspired with his twin brother, Jamaine Dontae Barnes, and others, to make and sell thousands of drug-laced pills. Barnes and his co-conspirators made the pills using pill presses, which are machines that compress powders into pills of various shapes and sizes. They made pills that appeared to be legitimate prescription pills but in fact contained fentanyl, furanyl fentanyl, heroin, and other synthetic opioids. They also made pills that appeared to be traditional Ecstasy pills but in fact contained methamphetamine. On May 16, 2019, law enforcement searched Jamar Barnes’ Stockton residence and seized a pill press machine as well as powders and pills containing methamphetamine and furanyl fentanyl. 

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.
