Buffalo Man Pleads Guilty in Cartel-Linked Cocaine Ring

Buffalo man Pethrod Dunnigan, 40, pleaded guilty to conspiracy to distribute five kilograms or more of cocaine and money laundering conspiracy, federal prosecutors announced today. The charges, tied to a sprawling drug trafficking ring with links to a Mexican drug cartel, carry a mandatory minimum of 10 years in prison, up to life, and a $20,000,000 fine.

Dunnigan admitted to conspiring between 2012 and March 2016 with Jose Manuel Lua-Guizar, Gerardo Ballardo, Enrique Munoz, Max Riestra, and others to distribute massive quantities of cocaine shipped from California. He paid $35,000 per kilogram and stored the drugs in an abandoned apartment at a Delaware Avenue building in Buffalo — a stash house in the heart of the city’s underworld pipeline.

The operation moved millions. Most of the illicit proceeds were laundered through structured deposits under $10,000 at multiple Bank of America branches across Buffalo — a deliberate tactic to evade federal reporting thresholds. Dunnigan personally made multiple such deposits, helping funnel over $1,000,000 in drug money. Investigators recovered a ledger detailing the cash drops from a stash house in California, where they also seized 21 kilograms of cocaine, three kilograms of heroin, and shipping materials.

On at least one occasion, Dunnigan escalated the scheme: he shipped approximately $500,000 in U.S. currency back to California by hiding bundles of cash inside a small refrigerator packed inside a wooden crate. The shipment, disguised as ordinary freight, exemplified the sophistication of the trafficking network’s logistics.

This case targets a seven-defendant organization that distributed drugs across New York, New Jersey, Illinois, Colorado, and Ohio. Four have already been convicted. Charges remain pending against the others. Authorities stress that an indictment is not a conviction — all defendants are presumed innocent until proven guilty in court.

The plea results from a joint investigation by the Drug Enforcement Administration, Immigration and Customs Enforcement’s Homeland Security Investigations, and the IRS Criminal Investigation Division, with support from ICE-HSI Los Angeles. Sentencing for Pethrod Dunnigan is set for May 8, 2018, at 3:00 p.m. before U.S. District Judge Elizabeth A. Wolford.
