Green Bay, WI – A major multi-county drug operation in Northeast Wisconsin led to 15 arrests Tuesday following a 14-month investigation into a large-scale trafficking network allegedly tied to Mexican drug cartels, according to the Brown County Sheriff’s Office.
The Brown County Drug Task Force, in coordination with the Lake Winnebago Area MEG Unit, executed 11 search warrants across Bellevue, Green Bay, Lawrence, and Neenah on October 29, 2025. Authorities say the operation dismantled a regional drug trafficking organization responsible for distributing cocaine and marijuana throughout Northeast Wisconsin.
According to the sheriff’s office, agents seized 2 kilograms of cocaine, 7 pounds of marijuana, 21 firearms, 2 vehicles, and $28,400 in cash during the raids.
Investigators also reported 23 additional arrests over the course of the 14-month investigation. Those earlier seizures included 1.2 kilograms of cocaine, 38 pounds of marijuana, 6 firearms, and $18,100 in cash.
The Brown County Sheriff’s Office credited several agencies for assistance, including the Green Bay Police Department, the DEA, FBI, and Wisconsin State Patrol.
Officials said those arrested will appear in court over the coming days. No further details are being released as the investigation remains ongoing.
