As part of a nine-month federal, state and local investigation, four more co-conspirators have pleaded guilty to a variety of federal drug trafficking and money laundering charges.
Thirteen defendants included in the organization have pleaded guilty so far.
U.S. Attorney for Idaho Wendy Olson said 31-year-old Isidoro David Herrerra, 22-year-old Alberto Abarca, 29-year-old Nicolas Olsen, all of Idaho Falls, and 26-year-old Ana Valdez-Ceja of Shelley pleaded guilty as part of a plea agreement in U.S District Court in Pocatello on Wednesday.
According to a news release, the four, as part of a large drug trafficking organization, obtained more than half a million dollars selling methamphetamine.
Prosecutors said several defendants made false loan application to local banks to further the laundering of that money.
They're scheduled for sentencing this spring.
