California Man Sentenced to 8 Years in Prison for Conspiracy to Distribute Methamphetamine

BOISE – Efrain Guzman-Castro, 42, of Woodland, California, was sentenced yesterday in United States District Court to 96 months in prison for conspiracy to distribute methamphetamine and distribution of methamphetamine, U.S. Attorney Wendy J. Olson announced. Chief U.S. District Judge B. Lynn Winmill also ordered that Guzman-Castro serve four years of supervised release and forfeit $2,986 in drug proceeds.


According to evidence presented in court, Guzman-Castro conspired with others to distribute large quantities of methamphetamine in the state of Idaho in early 2016. Guzman-Castro arranged with co-conspirators for delivers of methamphetamine in the Canyon County, Idaho, and Malheur County, Oregon, area. Investigating officers discovered the conspiracy and were able to make several controlled purchases of methamphetamine from Guzman-Castro and his co-conspirators.


Co-conspirator, Cinthia J. Velazquez, 28, of Woodland, California, also pleaded guilty to conspiracy to distribute methamphetamine and distribution of methamphetamine on December 12, 2016, and she is scheduled to be sentenced on March 13, 2017, before Chief U.S. District Judge B. Lynn Winmill.


The case was investigated by the Idaho State Police, the Drug Enforcement Administration, and the Nampa Police Department.
