Dominican National Gets 10 Years for Fentanyl Trafficking and Illegal Reentry
A Dominican national who illegally returned to the United States after deportation has been sentenced to a decade in federal prison for selling five kilograms of fentanyl to an undercover agent. The sentencing, handed down in Boston's federal court, highlights the ongoing intersection of drug trafficking and immigration enforcement.

The 10-Year Sentence
On September 30, 2025, U.S. District Court Judge Richard G. Stearns imposed a sentence of 10 years in federal prison on Luis Alberto German-Peguero, 35, a citizen of the Dominican Republic. The sentence also includes a five-year term of supervised release, a period during which German-Peguero will be subject to strict federal monitoring and conditions upon his release from custody. At the conclusion of his prison term, he faces mandatory deportation to the Dominican Republic under federal immigration law. The hearing took place in the U.S. District Court for the District of Massachusetts in Boston.
The 10-year prison term falls within the statutory range for the offenses, which carry significant penalties. Federal judges have discretion under advisory sentencing considerations to weigh factors such as the nature of the crime, the defendant’s personal history, and the need to protect the public. In this case, the court considered the large quantity of fentanyl involved—five kilograms—and the defendant’s prior drug trafficking conviction that had led to his removal from the United States in 2020. The sentence also takes into account German-Peguero’s illegal reentry, a separate federal crime that underscores his disregard for immigration law.
Supervised release will begin after German-Peguero completes his incarceration. During this period, he will be subject to conditions such as regular reporting to a probation officer, restrictions on travel, and potential drug testing. Violations of supervised release can result in additional imprisonment. The mandatory deportation provision means that upon release, German-Peguero will be transferred to the custody of U.S. Immigration and Customs Enforcement for removal proceedings. This outcome reflects the combined enforcement of federal drug and immigration statutes.
The sentencing was announced jointly by U.S. Attorney Leah B. Foley and Ted E. Docks, Special Agent in Charge of the FBI’s Boston Division. Assistant U.S. Attorney Stephen W. Hassink, of the Narcotics & Money Laundering Unit, prosecuted the case as part of an Organized Crime Drug Enforcement Task Forces (OCDETF) investigation, which targets high-level drug trafficking and criminal networks.
What Led to the Prison Term
The case against German-Peguero centered on a single large-scale drug transaction. On March 22, 2023, he sold five kilograms of fentanyl to an undercover law enforcement agent in Peabody, Massachusetts. Fentanyl is a synthetic opioid that is up to 100 times more potent than morphine and has been a major driver of overdose-related public safety concerns across the country. Five kilograms is a distribution-level quantity, far beyond personal use, indicating an intent to supply the drug to others. Undercover operations like this one are a common tool used by federal agents to build cases against suspected traffickers while avoiding the risks of street-level enforcement.
The transaction was not an isolated incident; it was part of a broader conspiracy that German-Peguero later admitted to in court. The charge of conspiracy to distribute fentanyl indicates that prosecutors believed he worked with others to move the drug, though the public release does not name any co-conspirators. The sale amount—five kilograms—placed the offense in the highest tier of federal drug penalties. Even without federal sentencing requirements being mentioned in the release, the volume alone is a strong aggravating factor in sentencing.
German-Peguero’s arrest came less than a month later. On April 14, 2023, authorities took him into custody in Newton, Massachusetts. During that arrest, law enforcement also determined that he was present in the United States illegally, having reentered after a prior deportation. This discovery added a second major federal charge to the drug case.
The Guilty Plea and Charges
In June 2025, German-Peguero pleaded guilty to three federal charges: conspiracy to distribute and possess with intent to distribute 400 grams or more of fentanyl; distribution and possession with intent to distribute 400 grams or more of fentanyl; and illegal reentry of a deported alien. By pleading guilty, he admitted to the factual basis of those offenses, which avoided a trial but did not prevent a substantial prison term.
The threshold of 400 grams of fentanyl is significant in federal drug cases. While the press release did not cite specific federal sentencing requirements penalties, quantities of that magnitude generally trigger heightened sentencing ranges. The plea may have reflected an acknowledgment of overwhelming evidence, including the undercover sale and subsequent investigation. However, no details were released about any cooperation or plea agreement that might have influenced the sentence.
The illegal reentry charge is a separate offense under 8 U.S.C. § 1326, which makes it a felony for a previously deported alien to enter, attempt to enter, or be found in the United States without permission. German-Peguero’s prior removal in November 2020 after a state drug conviction made this a straightforward case for federal prosecutors. The charge underscores the federal government’s focus on individuals who not only violate drug laws but also disregard immigration orders.
Illegal Reentry Background
German-Peguero’s immigration and criminal history played a key role in the case. According to the FBI release, he is a citizen of the Dominican Republic. In November 2020, he was removed from the United States following a state drug trafficking conviction in Plymouth Superior Court, for which he served more than one year in prison. That state-level offense, like the current federal case, involved serious drug trafficking, indicating a pattern of criminal activity.
After that removal, German-Peguero was legally barred from reentering the country without express permission. Federal law requires that non-citizens convicted of aggravated felonies, such as drug trafficking, are subject to permanent inadmissibility. Yet, sometime after his 2020 deportation, he managed to return to the United States and assume a residence in Chelsea, Massachusetts, where he lived unlawfully until his arrest in 2023.
The fact that he not only reentered but also resumed serious drug trafficking while unlawfully present raises questions about how he was able to cross the border undetected and establish himself in a community. The public release does not detail the manner of his reentry—whether by land, sea, or through a port of entry with fraudulent documents. It is also unclear how long after his removal he returned or how he supported himself before the undercover sting. These unresolved questions are common in illegal reentry cases, where proving the act of reentry is often easier than reconstructing the entire timeline.
The Undercover Operation and Arrest
The FBI and its task force partners targeted German-Peguero through an undercover operation, a hallmark of organized crime and drug enforcement. On March 22, 2023, an undercover agent met with the defendant in Peabody, north of Boston, and purchased five kilograms of fentanyl. The FBI release does not describe how the undercover agent initially connected with German-Peguero, but such operations typically involve informants, surveillance, or online investigations.
Less than a month later, on April 14, 2023, German-Peguero was arrested in Newton, a suburb west of Boston. The arrest may have followed further investigation and surveillance to build a solid case. At the time of arrest, authorities confirmed his unlawful presence in the United States, leading to the additional immigration charge.
No other individuals were publicly named in connection with the case, suggesting that German-Peguero may have been the primary target of the investigation, or that ongoing inquiries remain sealed. The FBI’s Boston Division, often involved in cross-border drug cases due to Boston’s port and proximity to drug trafficking routes, led the multi-agency effort. The case fell under the Organized Crime Drug Enforcement Task Forces (OCDETF) program, which coordinates federal, state, and local resources to disrupt major trafficking organizations.
Prosecutors and FBI Statement
The sentencing was announced jointly by United States Attorney Leah B. Foley for the District of Massachusetts and Ted E. Docks, Special Agent in Charge of the FBI’s Boston Division. While the press release did not provide direct quotes from these officials, their joint announcement signals the importance placed on the case by both the Department of Justice and the FBI. The prosecution was handled by Assistant U.S. Attorney Stephen W. Hassink of the Narcotics & Money Laundering Unit, a specialized unit experienced in complex drug and financial crime cases.
The release also emphasized that the case was part of an OCDETF operation, which targets high-level criminal organizations that threaten the United States. OCDETF uses a prosecutor-led, intelligence-driven, multi-agency approach to identify, disrupt, and dismantle these organizations. This case fits the OCDETF mission, as fentanyl trafficking often involves transnational networks with ties to foreign suppliers and distribution cells within the United States. German-Peguero’s unlawful reentry from the Dominican Republic after a prior drug conviction is precisely the kind of scenario that OCDETF is designed to address.
The announcement serves to inform the public of a significant sentence while also demonstrating the ongoing collaboration between federal agencies. It underscores the federal priority on combating fentanyl distribution, which has been a national public health crisis, and on enforcing immigration laws against repeat offenders.
The OCDETF Connection
The Organized Crime Drug Enforcement Task Forces (OCDETF) program was established in 1982 and is the premier tool for federal drug enforcement. OCDETF combines the efforts of multiple agencies—including the FBI, DEA, ATF, ICE, U.S. Marshals, and others—with prosecutorial leadership to go after the most significant drug trafficking and money laundering organizations. According to the Department of Justice website cited in the release, OCDETF “identifies, disrupts, and dismantles the highest-level criminal organizations that threaten the United States using a prosecutor-led, intelligence-driven, multi-agency approach.”
German-Peguero’s case, while not naming the specific OCDETF strike force, fits the typical profile of a targeted operation: a foreign national with a prior removal, a large fentanyl transaction, and an undercover sting. The OCDETF framework allows for a coordinated response that might include immigration consequences, asset forfeiture, and international cooperation—though none were detailed in the public release.
By designating this case under OCDETF, federal authorities signaled that they viewed German-Peguero as part of a larger drug trafficking threat, even if no co-conspirators were charged publicly. The program’s emphasis on dismantling entire organizations suggests that the investigation may continue, potentially uncovering more links in the supply chain. For now, the only outcome visible to the public is the decade-long prison term and eventual deportation.
Unanswered Questions
While the FBI release provides a clear account of the sentence and the basic facts, several aspects remain unknown. First, how did German-Peguero reenter the United States after his 2020 removal? The release gives no indication of whether he crossed the border clandestinely, used a fraudulent visa, or reentered through a port of entry under an assumed identity. Understanding the method of reentry could highlight vulnerabilities in border security that such cases often expose.
Second, the source does not disclose the origin or purity of the fentanyl. Fentanyl trafficked in the United States often comes from China or Mexico, but the release does not state where this five kilograms came from or how it was transported to Massachusetts. Additionally, the undercover operation raises questions about whether German-Peguero was a major distributor or a mid-level broker. Did he have suppliers? Did he have a network of customers? The conspiracy charge implies others were involved, but no other defendants are named.
Third, the time line between his reentry (after November 2020) and his undercover sale in March 2023 leaves a gap of potentially over two years. How did he support himself during that period? Was he involved in other criminal activity before the sting? The public record is silent.
Finally, the sentencing itself leaves open questions. Will German-Peguero appeal? Will he cooperate with authorities in exchange for a reduced sentence or other considerations? Will his deportation actually occur upon completion of his sentence, or will there be legal challenges? These are typical unknowns in federal criminal cases, and updates may follow as the case proceeds through post-sentencing and immigration processes.
