On Wednesday, May 20, 2020 a search warrant was served on a large-scale marijuana operation at 4955 Neighbors Blvd, located northwest of Palo Verde Valley College in the Blythe area. The grow operation covered over 200 acres, with approximately 360 green houses along with numerous other fixed and mobile structures. The search warrant was authored in response to information of a marijuana cultivation operation being run under the guise of a legal hemp operation. The Riverside County Agriculture Commission conducted a preliminary investigation which provided data the product being grown on the property was in fact marijuana.

The Riverside County Sheriff’s Department Emergency Services Team (EST) secured the property and detained more than 90 people. Deputies from the RSD- Colorado River Station coordinated the eradication effort with Department members from the Thermal and Palm Desert Station, as well as the Bureau of Land Management, Animal Control and Code Enforcement.

For three days, all participating agencies under the supervision of the Colorado River Station personnel with the assistance of the Palo Verde Irrigation District eradicated and removed over 114,049 marijuana plants and other materials used in the marijuana cultivation. The environmental impact of the illegal operation is yet to be determined and is still being evaluated.

The Special Investigations Bureau (SIB) assumed control of the criminal investigation of those detained for the illegal grow operation. SIB has task force officers from participating federal agencies, including Customs Border Protection (CBP) and Homeland Security Investigations (HSI). Those agencies sent additional resources to assist in processing those detained and to determine those responsible for running the illegal grow operation. Two principal suspects who owned and operated the land were taken into custody by Homeland Security Investigations. The remaining people detained were released from Sheriff’s custody. The investigation is ongoing.

Anyone with information regarding this investigation is encouraged to contact Sergeant Michael Yarbrough with the Special Investigations Bureau- Marijuana Eradication Team at 760-921-7900.
