Description: Portland, OR - Final Defendant Sentenced in Nayarit, Mexico-Based Heroin Trafficking Conspiracy

Misraim Israel Briones Pasos aka Mario Ozuna, 36, of Tepic, Nayarit, Mexico, was sentenced today to 151 months in prison for his role in a vast conspiracy responsible for trafficking hundreds of pounds of black tar heroin from Nayarit, Mexico to the Portland metropolitan area.

“Most of the heroin in this country came here across our porous Southern Border," Attorney General Sessions said. "Traffickers from Nayarit, like these defendants, have become notorious across the United States for their effectiveness in dispensing cheap and powerful heroin. We will never know the full extent of the consequences of their actions. The sentences handed down in this case, though they cannot compare with the damage done to our nation by the defendants, will help keep the people of this country safe. I want to thank our fabulous OCDETF members with the DEA, Homeland Security Investigations, the FBI, the IRS, the Marshals Service, and local police for their hard work, as well as Assistant U.S. Attorneys Thomas Edmonds and Steven Mygrant. They have done us all a service by taking heroin traffickers off of our streets.”

“At a time when communities are reeling from the effects of the opioid crisis, there are criminal organizations whose sole purpose is to profit off addiction. At its peak, this network was bringing up to 10 pounds of heroin into the Portland area every week – nearly 45,000 single doses,” said Billy J. Williams, U.S. Attorney for the District of Oregon. “Much of what law enforcement does to disrupt and dismantle these organizations is unknown to the public. The resolution of this case gives us a rare glimpse into the extraordinary work of law enforcement to bring every last person involved in a network’s operations to justice.”

“Lives are being lost at an alarming rate everyday due to opioid affliction,” said Keith Weis, Special Agent in Charge for the Drug Enforcement Administration (DEA) in Seattle. “We must be steadfast in stopping those most responsible for this shameful profiteering.”

According to court documents, investigators first learned of the conspiracy when a confidential informant provided a tip that co-defendant Cory Jaques was selling heroin and oxycodone from his residence in southwest Portland. Using controlled buys, surveillance and phone toll analysis, investigators determined that Jaques was receiving heroin from Briones Pasos and another co-defendant Melchor Luna Rodriguez. A federal wiretap investigation was opened in the fall of 2014.

Investigators later learned that Briones Pasos’ managed one of several heroin cells in the Portland area sourced by a single Nayarit-based supplier. The supply cell, managed by codefendants Christopher Guillen Robles and Paul Guillen, was responsible for bringing as much as 10 pounds of heroin into the metropolitan area every week. By early 2015, investigators had revealed the cells’ transportation methods and the movement of money via banks, bulk cash smuggling and wire transfers.

In February 2015, a federal grand jury in Portland returned a multi-count indictment implicating 22 defendants. Soon thereafter, investigators executed search and arrest warrants at 24 locations across four states. By February 2018, all principal targets had been convicted and the court had ordered more than $1.4 million in forfeiture money judgments.
