Gulfport man found guilty of running fentanyl operation from federal prison

A federal jury in Gulfport, Mississippi has convicted Marcus Agee, 35, on charges related to fentanyl trafficking. The verdict was reached after a three-day trial that concluded on January 14, 2026.

Evidence presented during the trial showed that Agee operated a drug trafficking conspiracy while serving a prison sentence at the Federal Bureau of Prisons facility in Beaumont, Texas. Authorities stated that Agee used contraband cell phones to communicate with members of the conspiracy through messaging applications, text messages, and video calls. He directed others to make fentanyl sales, transfer proceeds from those sales, and store fentanyl in Gulfport. He also arranged for shipments of fentanyl to be sent to Gulfport for distribution.

Law enforcement officials recovered over 900 grams of fentanyl and more than 15,000 counterfeit pills—some testing positive for fentanyl—linked to Agee’s activities.

Agee is scheduled for sentencing on May 12, 2026. He faces a mandatory minimum sentence of ten years in prison and could receive up to life imprisonment.

The investigation was conducted by the Drug Enforcement Administration with assistance from the Gulfport Police Department, Harrison County Sheriff’s Department, and Federal Bureau of Prisons.

Assistant U.S. Attorneys Hunter McCreight and Jonathan Buckner prosecuted the case.
