Madison, WI - Chadwick M. Elgersma, United States Attorney for the Western District of Wisconsin, announced the successful conclusion of a multiyear drug trafficking investigation in Dane County, following the sentencing of the last of thirteen defendants.

U.S. Attorney Elgersma praised the tireless efforts of the law enforcement agents throughout the State who worked together to dismantle this large-scale narcotics distribution organization. "These thirteen convictions mark a decisive blow against a multi-state criminal organization that threatened the safety of our communities. The success of this investigation is the direct result of a coordinated effort between federal, state, and local law enforcement partners who worked together, through a whole of government strategy, to dismantle a high-level fentanyl trafficking operation. I commend the investigators who worked tirelessly to protect families and hold the individuals who sell this poison accountable."

The investigation revealed a large-scale drug trafficking organization led by Lloyd McKire-Bennett that was responsible for bringing kilograms of fentanyl pills into Madison from Arizona. Law enforcement began investigating the organization in January 2022, following the seizure of two mail packages that each contained a kilogram of fentanyl pills (almost 20,000 pills in total). Both packages were mailed by individuals in Arizona to addresses in Madison.

The year-long investigation involved twenty-three controlled purchases of fentanyl pills, the seizure of a third drug-laden mail package (which contained 1.75 kilograms of fentanyl pills), arrests and warranted searches of residences and vehicles where narcotics and firearms were seized. As part of the investigation, officers seized almost 5 kilograms of fentanyl pills, 10 firearms, and over $97,000 in U.S. currency.
