A federal grand jury returned an indictment Thursday against two residents of Kern County, charging them in a conspiracy to distribute heroin, cocaine, and methamphetamine.

Mario Alvarez-Muniz, 49 and a citizen of Mexico living in Taft, and Darrell Leon Jennings, 49 of Bakersfield, were charged with conspiring to distribute heroin, cocaine, and meth and possession with intent to distribute heroin and cocaine.

Alvarez-Muniz was also charged with disturbing methamphetamine.

The Department of Justice released a press release detailing the case:

“According to court documents, Alvarez-Muniz, a self-employed tow truck driver, obtained heroin, cocaine, and methamphetamine from Mexico for distribution here. Jennings is a self-employed truck driver who assisted Alvarez-Muniz in transporting heroin and cocaine to Bakersfield for shipment to Chicago. Alvarez-Muniz was arrested in Bakersfield after delivering two pounds of methamphetamine during an undercover drug transaction and orchestrating a shipment of six kilograms of heroin and 11 kilograms of cocaine seized from Jennings’ truck.”

If convicted, Alvarez-Muniz and Jennings face a minimum statutory penalty of 10 years in prison and a maximum penalty of life in prison, along with a $10 million fine.
