The Sconi

A Madison man has been found guilty of drug trafficking offenses, including distributing cocaine, heroin, and fentanyl. Gregory P. Robinson, 41, was convicted after a three-day trial in federal court. The jury delivered the verdict after two hours of deliberation.

Acting U.S. Attorney Chadwick M. Elgersma announced the conviction. Evidence presented at the trial showed Robinson sold drugs to an undercover officer on four occasions in June 2024. These transactions involved cocaine, fentanyl, and heroin.

Law enforcement executed a search warrant on June 25, 2024, at Robinson's hotel room where they discovered over 500 grams of cocaine and heroin and more than 40 grams of fentanyl. They also found drug packaging materials and a money counter.

Testimonies from the Wisconsin State Crime Laboratory confirmed the substances' chemical composition while a Drug Enforcement Administration witness stated that the quantities indicated intent to distribute rather than personal use.

Chief U.S. District Judge James D. Peterson has set sentencing for October 2, 2025. Robinson faces up to 20 years for each distribution charge and maintaining a drug premises charge, with a minimum of five years for possession with intent charges.

The investigation was conducted by multiple agencies including the Madison Police Department and the Drug Enforcement Administration with assistance from ATF Madison Crime Gun Task Force. The case is prosecuted by Assistant U.S. Attorneys Colleen Lennon and William M. Levins.
