Brothers Robert T. Guerrero, Jr., 36, and Jason Daniel Guerrero, 34, who co-owned and operated head shops in Nampa and Kuna, were sentenced Tuesday to more than a year in prison in U.S. District Court in Boise.
They both pleaded guilty to one count of offering drug paraphernalia for sale and one count of money laundering.
Robert Guerrero was sentenced to 18 months, while his younger brother received a 15-month sentence.
The brothers co-owned and operated RG Distributing, Inc., which did business as the Smoke Shack, 124 13th Avenue South, Nampa, and Smoke Shack 2, 482-A W. Main Street in Kuna.
In addition to selling drug paraphernalia, the Guerreros also manufactured and distributed the illegal drug "spice," a synthetic form of marijuana, the federal prosecutor's office said in a press release. With some of the $120,000 in cash gained from drug paraphernalia sales, each of the brothers purchased diamond jewelry.
The Guerreros were two of 18 people charged in 2012 as part of "Operation Not for Human Consumption," which targeted illegal sales of drug paraphernalia and spice at 13 Treasure Valley businesses.
