BOISE, Idaho - Ubaldo Soto-Diaz, an illegal alien from Mexico, but residing in Portersville, California, was sentenced to 25 years in prison for conspiracy to distribute methamphetamine and heroin. Chief U.S. District Judge David C. Nye also ordered Soto-Diaz to pay a $2,000 fine and serve five years of supervised release following his prison sentence. Soto-Diaz pleaded guilty to the charge on July 18, 2019.

According to court records, Soto-Diaz admitted that between Aug. 28, 2018, and Jan. 28, 2019, he conspired with six other defendants to distribute methamphetamine and heroin. Soto-Diaz was found to be the leader and organizer of an extensive criminal organization that was responsible for distributing high potency methamphetamine, manufactured in Mexico and then transported from California to Idaho. During their investigation of Soto-Diaz and his organization, DEA agents seized over thirty pounds of 100 percent pure methamphetamine and almost two pounds of black tar heroin.

According to court records, Soto-Diaz had previously been convicted of transporting a controlled substance in 2000 and possession of controlled substances for sale in 2009. He was deported to Mexico on May 17, 2010. He was found to be illegally present in the United States on May 26, 2010, and was convicted of illegal entry. He again illegally returned to the United States and was convicted of possession of controlled substances for sale and unlawful possession of a firearm in 2012. At the time Soto-Diaz conspired to distribute methamphetamine and heroin to Idaho, he was illegally living in Portersville, California.
