EVANSVILLE— Two men have been sentenced to a combined 16 years in federal prison for their roles in a drug trafficking operation responsible for pumping thousands of counterfeit fentanyl pills from Arizona into Evansville.

Deriontai Mathis, 31, of Evansville, has been sentenced to 11 years in federal prison followed by five years of supervised release after pleading guilty to possession with intent to distribute fentanyl, two counts of possession of a firearm by a convicted felon and conspiracy to distribute fentanyl.

Ernest Gilbert, 38, of Arizona, was sentenced in July of 2024 to five years in federal prison followed by three years of supervised release after pleading guilty to distribution of fentanyl and conspiracy to possess with intent to distribute 400 grams or more of fentanyl.

According to court documents, between September and November of 2022, Mathis and Gilbert conspired together to buy and sell thousands of fentanyl-laced counterfeit oxycodone pills. Gilbert, who resided in Arizona, would obtain the pills, ship or otherwise transport them to Indiana, and then fly to Indiana and drive the pills to Mathis in Evansville.

On November 10, 2022, during a search of Mathis’s residence, investigators recovered nine plastic bags containing ten thousand counterfeit M-30 fentanyl pills hidden inside of a child’s toy car, a camouflaged backpack that contained $56,800.00 in cash, a body armor vest and nine firearms. During a search of another residence Mathis used to store his contraband, officers recovered three additional handguns and a 12-gauge shotgun.

In 2015, Mathis was convicted for being a drug abuser in possession of a firearm, thereby prohibiting from ever legally possessing a firearm again.

This investigation also led to the discovery that Jeremial Leach was a customer of Mathis, purchasing counterfeit fentanyl pills for $10 per pill. In May of 2024, Leach was sentenced to 20 years in federal prison for dealing fentanyl resulting in at least three overdoses and a teen’s death.

“The sentences imposed here should serve as a warning: these poisons kill—and selling them will earn you decades in federal prison,” said John E. Childress, Acting United States Attorney for the Southern District of Indiana. “Our office remains committed to working hand in hand with our state, local and federal partners in order to keep our communities safe, hold drug traffickers accountable, and stop the flow of deadly substances into our neighborhoods.”

The Drug Enforcement Administration, Bureau of Alcohol, Tobacco, Firearms and Explosives, Evansville-Vanderburgh County Drug Task Force and Evansville Police Department investigated this case. The sentences were imposed by U.S. District Judge Richard L. Young.

Acting U.S. Attorney Childress thanked Assistant U.S. Attorney Lauren Wheatley, who prosecuted this case.
