A Florissant man is headed to federal prison for a decade after a St. Louis judge said his home had effectively doubled as a stash house for drugs and guns. On Wednesday, U.S. District Judge Matthew T. Schelp sentenced 42-year-old Melvin Nelson to 10 years behind bars after Nelson admitted he was trafficking meth and holding firearms as a convicted felon, following two separate searches that uncovered methamphetamine, fentanyl, multiple guns and nearly $39,000 in cash.
According to a press release from the U.S. Attorney's Office for the Eastern District of Missouri, Nelson pleaded guilty to one count of possession with intent to distribute methamphetamine, one count of possession of one or more firearms in furtherance of a drug trafficking crime and one count of being a felon in possession of a firearm. Prosecutors said he admitted the evidence from a Sept. 4, 2024 warrant at his residence and a later Aug. 26, 2025 federal warrant at the same address. Assistant U.S. Attorney Ricardo Dixon handled the case.
Court records and local reporting say officers first hit Nelson’s home in the 2200 block of Gadbury Drive on Sept. 4, 2024. Inside his bedroom they found a handgun, $38,892 in cash and at least 219 grams of methamphetamine in pill form, with scales and other drug packaging gear discovered in the basement. An AR-style pistol and body armor turned up in the garage, while bags containing cocaine and fentanyl were pulled from the backyard, according to KTTN News. Those items match the inventory listed in the federal case file and in the U.S. Attorney’s release.
Aug. 2025 ATF Search Uncovered Hundreds Of Grams Of Fentanyl
Federal agents were back less than a year later. On Aug. 26, 2025, the Bureau of Alcohol, Tobacco, Firearms and Explosives executed federal arrest and search warrants at the same Florissant home and seized a rifle, a pistol and at least 500 grams of a fentanyl mixture, prosecutors said in the U.S. Attorney's Office release. Officials pointed to the large quantity of drugs and the guns on site as evidence the property was being used to store and package narcotics for sale rather than personal use.
Legal Note
The firearm charges Nelson admitted are typically brought under federal statutes that carry mandatory minimum penalties. Title 18 U.S.C. § 924(c) covers possession of a firearm in furtherance of a drug trafficking crime and 18 U.S.C. § 922(g) bars felons from having guns, according to the Legal Information Institute at Cornell Law School (LII). The investigation involved the Florissant Police Department, the St. Louis County Police Department, the U.S. Marshals Service and the ATF, and Assistant U.S. Attorney Ricardo Dixon prosecuted the case, according to KTTN. Federal firearm and drug laws give judges significant prison time to work with at sentencing, which helps explain the 10 year term Nelson received.
Why This Matters In Missouri
Prosecutors highlighted the volume of drugs seized, including packaged meth and hundreds of grams of fentanyl, as especially alarming in a state that is still battling opioid deaths. Synthetic opioids like fentanyl remain a leading driver of opioid involved fatalities in Missouri, even as preliminary data suggests a modest decline in overall overdose deaths statewide, according to the Missouri Department of Health and Senior Services. Seizures of this size in north St. Louis County keep pressure on law enforcement to disrupt local distribution networks that can fuel overdoses across the region.
Nelson’s sentence includes 10 years in federal prison, to be followed by a term of supervised release once he is out. Federal officials framed the case as a textbook example of local and federal agencies teaming up to pull guns and high potency narcotics out of a neighborhood before they could do more damage.
