373 pounds of methamphetamine worth over $1 million seized in Lane County, Oregon’s largest ever

Five arrested; firearms, cash also seized

EUGENE, Ore. (KTVZ) — Federal prosecutors announced Monday that a break-up of a Lane County drug ring led to five arrests and Oregon's largest methamphetamine seizure in state history: 384 pounds, worth over $1 million.

Here's the full announcement from the U.S. Attorney's Office in Portland:

On Sept. 15, a coordinated law enforcement operation targeting the leader and several associates of a Lane County drug trafficking cell led to the seizure of 384 pounds of methamphetamine, the largest single methamphetamine seizure in Oregon state history and valued at over a million dollars.

The operation, led by the U.S. Drug Enforcement Administration, with assistance from the Springfield Police Department, Eugene Police Department, and Linn Interagency Narcotics Enforcement Team (LINE), came after the cell’s leader, Martin Manzo-Negrete aka Javier Cardenas-Manzo, a 47-year-old Eugene resident, was charged by federal criminal complaint with possessing with intent to distribute methamphetamine. Manzo-Negrete has a long history of drug trafficking and previously served 14 years in federal prison.

Manzo-Negrete was arrested during the operation and made his first appearance in federal court on September 16, 2021. He was ordered detained pending further court proceedings.

Four of Manzo-Negrete’s associates were also arrested and are facing federal drug charges. They include Eugene residents Gustavo Manzo-Mares, 45; Candice L. Barrett, 52; John C. Willis, 59; and Nathan Lee Daniels, 46. A fifth associate, Frank Buehler, 52, also of Eugene, has been charged, but remains at large.

As part of the operation, law enforcement executed federal search warrants at multiple locations in Lane County. In addition to methamphetamine, they seized 14 firearms—some of which were stolen—and more than $76,000 in cash.

DEA and the Eugene Police Department Street Crimes Unit began investigating the Manzo-Mares cell in October 2020 for its role in trafficking large quantities of methamphetamine from California to Oregon for resale in and around Lane County. The drug trafficking organization transported large quantities of methamphetamine by car from Southern California to Oregon. Once in Oregon, the drugs were stored, divided, and then distributed into the community.

Acting U.S. Attorney Scott Erik Asphaug of the District of Oregon made the announcement.

This case was investigated by the DEA with assistance from Springfield Police Department, Eugene Police Department Street Crimes Unit, and LINE. Assistant U.S. Attorney Joseph H. Huynh is prosecuting the case.

A criminal complaint is only an accusation of a crime, and defendants are presumed innocent unless and until proven guilty.
