Multi-Kilogram Fentanyl Seizure in Homeland Security Task Force Investigation Nets Guilty Plea by Fort Walton Beach Man

Pensacola, Florida - Aubrey Darnell Joseph Sr., 36, of Fort Walton Beach, Florida, pleaded guilty in federal court to conspiracy to distribute and possess with intent to distribute 400 grams or more of fentanyl and possession with intent to distribute 400 grams or more of fentanyl. John P. Heekin, United States Attorney for the Northern District of Florida announced the charges.

U.S. Attorney Heekin said: "President Donald J. Trump designated fentanyl as a weapon of mass destruction because of the utter devastation it has wrought on communities nationwide, and this criminal was caught peddling large quantities of this deadly drug to make a profit off of the death and despair it inflicts. Thanks to the outstanding investigative work of our state and federal law enforcement partners, supported by the Gulf Coast High Intensity Drug Trafficking Area Task Force, his days of threatening the health and safety of our communities are now at an end."

Court records establish that between 2024 and 2026, the defendant participated in a conspiracy to obtain and distribute large quantities of fentanyl in the Northern District of Florida. In April 2026, federal authorities executed a search warrant at the defendant's house in Fort Walton Beach, during which nearly two and a half kilograms of fentanyl, an industrial sized press and multiple press plates, and almost $5,000 in cash were found and seized.

The defendant faces a minimum mandatory sentence of 10 years' imprisonment, and up to life imprisonment, on each count.

The case was investigated by the Drug Enforcement Administration and the Okaloosa County Sheriff's Office, with assistance from the Gulf Coast High Intensity Drug Trafficking Area (HIDTA) Task Force. The case is being prosecuted by Assistant United States Attorneys Jessica S. Etherton and Alicia H. Forbes.
