Fentanyl Dealer Sentenced to More Than a Decade in Federal Prison
A Dubuque, Iowa man who distributed fentanyl for more than a year and illegally held a loaded firearm has been sentenced to 137 months in federal prison, according to a public release from the Federal Bureau of Investigation and court records. The sentence, handed down on May 18, 2026, by United States District Court Chief Judge C.J. Williams, follows the defendant's guilty plea in December 2025 to multiple federal charges, including conspiracy to distribute 40 grams or more of fentanyl and being a prohibited person in possession of a firearm.

The Sentence
Derrick Deonte Moore, 31, of Dubuque, was sentenced to a term of 137 months—just over 11 years—in federal prison. The sentence was imposed by Chief Judge C.J. Williams of the United States District Court for the Northern District of Iowa in Cedar Rapids. Moore had entered a guilty plea on December 22, 2025, to conspiracy to distribute 40 grams or more of fentanyl, possession with intent to distribute fentanyl, possession of a firearm by a prohibited person, and distribution of fentanyl.
In addition to the prison term, Moore was ordered to serve a five-year period of supervised release after he completes his incarceration. Supervised release is not the same as parole; it is a period of monitoring by federal probation officers that follows a prison sentence and imposes conditions such as regular check-ins, drug testing, and restrictions on travel and association. There is no parole in the federal system, meaning Moore will be required to serve at least 85% of his 137-month sentence before any good-time credit can reduce his time in custody. Officials with the United States Marshals Service are holding Moore until he can be transported to a federal prison facility.
The Case Behind the Prison Term
According to prosecutors and evidence presented during plea and sentencing hearings, between July 1, 2022, and October 10, 2023, Moore worked with others to distribute fentanyl in the Dubuque area. The conspiracy involved at least 40 grams of fentanyl, a quantity that triggers stricter penalties under federal law. Moore admitted his role in the conspiracy and the distribution charges during his guilty plea. The conspiracy involved the sale of pills containing fentanyl, a powerful synthetic opioid that has been at the center of a nationwide overdose crisis. Moore's actions were not isolated: he distributed fentanyl on multiple dates and, in at least two instances, his product was connected to nonfatal overdoses in October and December of 2023.
Moore's plea agreement resolved all charges against him, and he admitted to the core allegations. The government's case included evidence that Moore sold ten fentanyl pills to another person on September 6, 2023, and again on October 10, 2023. These transactions, along with the items recovered from his home, formed the basis for the distribution and possession charges.
What Investigators Found in Moore's Home
A critical turning point in the investigation came in March 2023, when investigators executed a search warrant at Moore's Dubuque residence. Inside the home, they found Moore himself, along with more than $2,500 in cash. The search uncovered 234 fentanyl pills hidden inside a stuffed animal—an attempt, investigators said, to conceal drugs from routine discovery. An additional five fentanyl pills were found in a bag inside Moore's bedroom closet. The cash found on Moore, over $2,500, was may have proceeds from drug sales. The presence of a scale alongside the drugs indicated that Moore was involved in measuring and packaging fentanyl for distribution.
The same closet also held a loaded .45 caliber pistol. Next to it, investigators seized a scale, a variety of prescription drugs, and marijuana. The combination of drugs, drug-packaging paraphernalia, and a firearm painted a picture of a small-scale but active fentanyl operation run out of a private home.
The pills recovered from the stuffed animal and closet matched the type of fentanyl pills Moore was later accused of selling. Authorities tied the March 2023 search directly to the ongoing distribution conspiracy, indicating that Moore had been actively selling fentanyl both before and after the search.
The Firearm Charge
Moore's possession of the loaded .45 caliber pistol was illegal for a specific reason: he was a "prohibited person" under federal law. The term applies to individuals who cannot lawfully possess a firearm because of prior felony convictions or certain misdemeanor convictions involving domestic violence. According to court records cited by prosecutors, Moore had prior felony and domestic abuse assault convictions, which barred him from owning or handling any firearm. Being a prohibited person due to prior felony and domestic abuse assault convictions meant Moore was breaking federal law simply by having the firearm in his possession, regardless of whether he used it.
The firearm charge illustrates a pattern that federal officials have emphasized: the intersection of drug trafficking and illegal gun possession. The presence of a loaded weapon near fentanyl and distribution tools raises concerns about violence and the potential harm to the community. While there is no public suggestion from authorities that Moore used the gun during a specific drug transaction, its location and the circumstances of the case were enough to add a significant federal charge.
Nonfatal Overdoses Linked to Moore
Two nonfatal overdoses in October and December 2023 were directly linked to fentanyl that Moore distributed, prosecutors said. The timing of those overdoses—after the March 2023 search of his home—indicates that Moore continued to sell fentanyl even after law enforcement had seized drugs and a firearm from his residence. Federal prosecutors highlighted these overdoses as a key aggravating factor in the case, emphasizing the real-world harm caused by fentanyl distribution. Although the victims survived, such incidents demonstrate the dangerous nature of the drug.
Federal officials have increasingly used overdose-linked prosecutions to hold dealers accountable. In cases where a death occurs, charges can escalate to distribution resulting in death or serious bodily injury, which carry a federal sentencing requirements of 20 years. In this case, because the overdoses were nonfatal, Moore faced the charges he pleaded to: conspiracy and distribution, among others. Still, the link between his conduct and the overdoses was noted by the court as a serious aggravating factor.
The Multi-Agency Investigation
The prosecution involved a wide-ranging collaboration among federal, state, and local law enforcement agencies. The case was prosecuted by Special Assistant United States Attorney Michael S.A. Hudson and Assistant United States Attorney Dan Chatham of the Northern District of Iowa. The investigation was carried out by:
- Federal Bureau of Investigation (FBI)
- Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF)
- Dubuque Drug Task Force
- Dubuque Police Department
- Dubuque County Sheriff's Office
- Iowa Division of Criminal Investigation Criminalistics Laboratory
The involvement of multiple agencies highlights the coordinated approach often used in drug trafficking cases that cross jurisdictional lines or involve federal firearm statutes. The Dubuque Drug Task Force, a specialized unit that combines resources from various local law enforcement agencies to target drug trafficking, played a key role in the initial investigation and search. The participation of the Iowa Division of Criminal Investigation Criminalistics Laboratory indicates that forensic analysis was performed on the seized substances to confirm they were fentanyl.
Operation Take Back America
The Department of Justice identified Moore's case as part of Operation Take Back America, a nationwide initiative that marshals federal resources to target illegal immigration, cartels, transnational criminal organizations, and violent crime. Operation Take Back America emphasizes aggressive prosecution of drug trafficking networks and firearm offenses. Under this initiative, the Department of Justice prioritizes resources for combating violent crime and drug trafficking networks. The designation of Moore's case under Operation Take Back America underscores the federal government's focus on fentanyl-related offenses.
It is not unusual for a federal case to be designated under a broader national operation, particularly when it involves fentanyl, a substance frequently associated with cartel-linked supply chains. However, specifics about whether Moore's supply originated from a larger trafficking organization were not detailed in the public release.
The Sentencing Determination
During the sentencing hearing, Chief Judge C.J. Williams heard evidence and arguments before imposing the 137-month prison term. Under federal law, judges consider the advisory sentencing considerations, the nature and circumstances of the offense, and the defendant's background. The public release did not disclose the specific guideline range or the judge's reasoning, but the sentence reflects a significant prison term for the combined drug and firearm offenses. Moore's prior felony and domestic abuse assault convictions may have played a role in the sentence length, as prior criminal history can increase the guideline range. However, without access to the presentence report, the exact justification remains confidential.
Why This Sentencing Matters
The case underscores several public safety issues that have drawn sustained attention from law enforcement and community leaders in Iowa and across the country. First, fentanyl remains a primary driver of overdose-related public safety concerns, and even small quantities can have deadly consequences. The fact that Moore's distribution led to two nonfatal overdoses—and that he continued selling after a law enforcement search—demonstrates the persistence of some low-level dealers.
Second, the presence of a loaded firearm near drugs and the proceeds of drug sales is a recurring element in federal prosecutions. When a prohibited person possesses a gun, it elevates the danger and the potential for violence. Federal law treats such possession seriously, often adding years to a sentence.
Third, the case highlights the role of local task forces and FBI field offices in pursuing mid-level drug cases that might otherwise remain under the radar. While much public attention focuses on large cartel busts, many federal prosecutions stem from targeted work like the Dubuque investigation.
Moore's sentence of more than a decade in prison sends a direct message: individuals who repeatedly distribute fentanyl and illegally arm themselves will face significant prison time. The sentence serves as a warning to others involved in similar activities that federal authorities will pursue and prosecute such crimes vigorously. However, deterrence alone cannot solve the underlying demand and addiction issues that fuel such markets.
What Remains Publicly Unknown
Despite the detail in the release, several aspects of the case are not publicly known. The government did not disclose the exact nature of Moore's prior felony and domestic abuse assault convictions. It is unclear whether other individuals named in the conspiracy have been charged or convicted. The release implies that Moore worked with others, but no additional defendants are identified.
The source of Moore's fentanyl supply was not revealed. Whether pills came from a local or interstate network, or whether Moore acted as a middleman for a larger distributor, remains an open question. Likewise, whether the two overdose victims survived without permanent harm was not stated.
Additionally, the public release did not disclose the specific terms of the supervised release that Moore will face, which will be set by the probation office closer to his release date.
Finally, the specific reasons for the 137-month sentence—whether it fell within a recommended guideline range or reflected an upward or downward departure—were not detailed. Federal sentencing is complex, and judges consider many factors before imposing a term. The supervised release conditions for Moore after his prison term will may have be determined closer to his release date.
