Dennis E. McMullen, a 69-year-old from Purdy, Missouri, has been sentenced to 96 months in federal prison for trafficking a cocktail of deadly drugs, including fentanyl, cocaine, and heroin. The bust went down on July 30, 2024, when investigators from the DEA, Ozarks Drug Enforcement Team, and Barry County Sheriff’s Office executed a search warrant on McMullen’s residence. The raid followed a controlled purchase of fentanyl from McMullen, which led to the discovery of a stash of controlled substances, paraphernalia, and a firearm.
Inside McMullen’s kitchen, investigators found plastic baggies containing suspected controlled substances, including a baggie hidden inside a plastic tub of candy. The upstairs bedroom yielded a Jennings model J-22 .22 caliber pistol, several boxes of ammunition, and two additional baggies of a white powder-like substance. A vehicle parked outside also contained a bag of a white powder-like substance.
Lab analysis revealed a staggering array of substances, including 8.1 grams of fentanyl and lidocaine, 31.874 grams of cocaine, and .087 grams of a deadly mix of fentanyl, heroin, cocaine, lidocaine, and xylazine. McMullen pleaded guilty to the offenses on September 29, 2025, and has been sentenced to eight years in federal prison, followed by five years of supervised release.
Chief United States District Judge Brian C. Wimes handed down the sentence, bringing an end to McMullen’s reign as a major player in the Missouri drug trade. The case highlights the ongoing struggle against fentanyl trafficking in the United States, which has claimed thousands of lives in recent years.
