Gregory P. Robinson, Cocaine, Heroine, Fentanyl Trafficking, Wisconsin 2024

A Madison man has been convicted of distributing cocaine, heroin, and fentanyl in Wisconsin. Gregory P. Robinson, 41, was convicted following a three-day trial in federal court in Madison.

The jury reached a verdict today after just over two hours of deliberation. The guilty verdict is announced by Chadwick M. Elgersma, Acting U.S. Attorney for the Western District of Wisconsin.

The government presented evidence at trial that Robinson sold controlled substances to an undercover police officer in Madison on four occasions in June 2024. Robinson sold cocaine on June 3; cocaine and fentanyl on June 6; and cocaine, fentanyl and heroin on June 13 and June 20.

On June 25, 2024, law enforcement executed a search warrant at the hotel room where Robinson was staying. In the room, officers located more than 500 grams of cocaine, heroin, and more than 40 grams of fentanyl. Officers also located drug packaging materials, ingredients to manufacture crack cocaine, a money counter, and U.S. currency.

A witness from the Wisconsin State Crime Laboratory confirmed the chemical composition of the controlled substances. A witness from the Drug Enforcement Administration testified that the quantities of cocaine and fentanyl found in the hotel room were consistent with an intent to distribute the drugs rather than an intent to use the drugs personally.

Gregory P. Robinson is facing a maximum penalty of 20 years in federal prison for each drug distribution charge and the maintaining a drug involved premises charge. For each possession with intent charge, he faces a mandatory minimum penalty of 5 years in prison and a maximum penalty of 40 years in prison.

Gregory P. Robinson is scheduled to be sentenced on October 2, 2025. The case was investigated by the Madison Police Department, Dane County Narcotics Task Force, and the Drug Enforcement Administration with assistance from the ATF Madison Crime Gun Task Force.

The prosecution is being handled by Assistant U.S. Attorneys Colleen Lennon and William M. Levins.
