Violent Armed Drug Trafficker from Boise's North End Sentenced to 262 Months in Federal Prison
BOISE – Evan Nickolai Ernstson, 48, of Boise, was sentenced to 262 months in federal prison for conspiracy to distribute methamphetamine, Acting U.S. Attorney Justin Whatcott announced today. Senior U.S. District Court Judge B. Lynn Winmill also sentenced Ernstson to serve five years of supervised release upon completion of his prison sentence and pay a $2000 fine.
According to court records, Ernstson, originally from San Francisco, California, led a drug trafficking organization that distributed methamphetamine and cocaine between October 2023 and March 2024 out of a residence and various other locations in Boise’s North End neighborhood. A lengthy investigation by the Drug Enforcement Administration (DEA), which included a wiretap, culminated in the seizure of ten pounds of methamphetamine, a kilogram of cocaine, and four firearms. On March 20, 2024, Ernstson was arrested as he returned to Idaho after picking up a load of methamphetamine and cocaine from the Portland, Oregon area. He was armed with a loaded 9mm handgun.
Law enforcement, while conducting the wiretap, learned that someone stole approximately $65,000 in drug proceeds from Ernstson while he was out of town. DEA Agents intercepted Ernstson’s calls and texts and learned Ernstson planned to kidnap two individuals, zip-tie them and torture them until the money was returned. Agents intervened and prevented the kidnapping and seized approximately $42,000 of the stolen drug proceeds.
Ernstson is the third member of the drug trafficking organization to be sentenced to prison. Co-defendant Eva Spikes pleaded guilty to distributing methamphetamine and was sentenced to five years in prison on November 5, 2024. Co-defendant Leandru Stephens pleaded guilty to distributing methamphetamine and was sentenced to five years in prison on December 11, 2024. The remaining four co-defendants have pleaded guilty to various drug trafficking charges and will be sentenced in May 2025.
The investigation into Ernstson’s drug trafficking organization also resulted in the conviction and sentence of three other individuals involved in drug trafficking. Dustin Wyatt Peymon, 53, of Boise, pleaded guilty to distributing methamphetamine and was sentenced to 33 months in prison on November 6, 2024. Kristine Marie Shern, 28, of Mountain Home, pleaded guilty to misprision of a felony and was sentenced to three years’ probation on February 4, 2025. Brian Earl Polk, 26, of Boise, pleaded guilty to distributing methamphetamine and was sentenced to 77 months in prison and four years of supervised release on April 15, 2025.
“Mr. Ernstson led a drug trafficking ring that not only poisoned Idaho with large quantities of methamphetamine and other drugs, but was poised to kidnap and torture to further his criminal enterprise,” said David F. Reames, Special Agent in Charge, DEA Seattle Field Division. “This lengthy sentence ensures our community’s safety and demonstrates law enforcement’s steadfast resolve to protect our citizens from people like Mr. Ernstson.”
“Our federal and state partners work together tirelessly to ensure that drug traffickers, especially those who are violent or armed, find no safe harbor in Idaho,” stated Acting U.S. Attorney Justin Whatcott.
Acting U.S. Attorney Whatcott commended the work of the Drug Enforcement Administration, the Boise Police Department, the Nampa Police Special Investigations Unit, the Ada County Sheriff’s Office, and the Elmore County Sheriff’s Office, which led to the charges. Assistant U.S. Attorneys Erin C. Blackadar and Christian S. Nafzger prosecuted the case.
This prosecution is part of an Organized Crime Drug Enforcement Task Forces (OCDETF) investigation. OCDETF identifies, disrupts, and dismantles the highest-level drug traffickers, money launderers, gangs, and transnational criminal organizations that threaten the United States by using a prosecutor-led, intelligence-driven, multi-agency approach that leverages the strengths of federal, state, and local law enforcement agencies against criminal networks.
