Main Facts
A convicted felon from Massachusetts has pleaded guilty in federal court to an extraordinary array of charges linking international nuclear smuggling, illicit hazardous materials distribution, firearms violations, and child sexual abuse material (CSAM).
Jacob D. Miller, 44, entered a guilty plea in the U.S. District Court for the District of Massachusetts. The plea resolves a multi-agency federal investigation that exposed an online business operation through which Miller illegally imported radioactive plutonium from the Russian Federation and sold it, along with other highly toxic chemicals, to domestic and international buyers.
According to the U.S. Attorney’s Office for the District of Massachusetts, Miller pleaded guilty to five distinct federal counts:
- One count of importing nuclear material without lawful authority;
- One count of mailing hazardous materials;
- One count of being a felon in possession of ammunition;
- One count of being a felon in possession of explosive materials; and
- One count of possession of child pornography.
The case has drawn significant attention from national security experts, postal inspectors, and nuclear non-proliferation officials due to the ease with which weapons-grade or highly radiotoxic elements were smuggled across international borders and distributed through standard commercial mail channels. Miller has remained in federal custody since his arrest in April 2025. His sentencing is scheduled for January 21.

The 2004 Prior Convictions
On February 9, 2004, Miller was convicted in a Massachusetts state court on two separate criminal matters. In the first case, he was convicted of possessing child pornography and sentenced to seven years of probation. In the second case, which involved two counts of possessing an explosive device, Miller was sentenced to two and a half years in jail followed by ten years of probation. Under federal law, these felony convictions permanently barred Miller from legally possessing firearms, ammunition, or explosive materials.
The Launch of "Collect The Periodic Table" (2017)
Following his release from state custody and the completion of his supervision, Miller established an e-commerce business called "Collect The Periodic Table" (CTPT). The business marketed itself to chemistry enthusiasts, element collectors, and educational institutions, offering physical samples of various elements from the periodic table.
To expand his market reach beyond his proprietary website, Miller utilized Bonanza, an online third-party retail marketplace. On October 12, 2017, Miller began using these platforms to sell and ship thallium—a highly toxic heavy metal historically used as a rodenticide and classic homicidal poison—to customers worldwide.
The Russian Plutonium Pipeline (2020–2025)
In late 2020, Miller expanded his inventory to include radioactive isotopes. According to federal prosecutors, Miller established a supply chain with an unnamed source in Russia to illegally import plutonium.

Between December 30, 2020, and March 31, 2025, Miller successfully bypassed international customs controls to have plutonium shipped directly from Russia to his residence in Massachusetts. Once received, Miller portioned the radioactive material and sold it to approximately 67 customers across the United States and abroad. To fulfill these orders, Miller packaged the plutonium and deposited it into the United States Postal Service (USPS) network, despite federal regulations strictly prohibiting the mailing of hazardous radioactive materials.
Investigation, Raid, and Arrest (April 2025)
Federal law enforcement authorities, including the FBI and the U.S. Postal Inspection Service, intercepted shipments and compiled evidence of Miller’s illicit supply chain. On April 9, 2025, federal agents executed a coordinated raid on Miller’s Massachusetts residence and arrested him.
During the search, investigators recovered:
- Six firearms;
- Numerous rounds of live ammunition, including .45-caliber rounds;
- A box containing multiple bottles of explosive powder;
- Digital devices, including a laptop and a cellular telephone, containing active files of child sexual abuse material. Forensic analysis revealed that Miller had accessed these illicit files as recently as April 8, 2025—the day before his arrest.
On April 17, 2025, a federal grand jury in Boston returned a formal indictment against Miller. He has remained detained without bail as a flight risk and a danger to the community.
Supporting Data
The scale of Miller’s operations highlights significant vulnerabilities in domestic postal security and international customs enforcement.
Illicit Chemical and Radiological Sales Data
Court documents detail the volume of transactions processed by Miller through CTPT and Bonanza over several years:
| Substance | Hazard Classification | Customer Count | Operational Period | Primary Delivery Method | Sourcing Origin |
|---|---|---|---|---|---|
| Thallium | Highly Toxic Heavy Metal | ~71 customers | Oct 12, 2017 – Apr 5, 2025 | U.S. Mail (USPS) | Unspecified |
| Plutonium | Highly Radioactive Actinide | ~67 customers | Dec 30, 2020 – Mar 31, 2025 | U.S. Mail (USPS) | Russian Federation |
Toxicological and Radiological Profiles of Seized Materials
Plutonium
Plutonium is a synthetic, highly radioactive element. While certain isotopes are utilized in nuclear reactors and scientific instruments, plutonium-239 is a key fissile material used in nuclear weapons.
Even in microscopic quantities, plutonium poses severe radiological hazards. It is an alpha-emitter; if inhaled or ingested, plutonium particles lodge in lung, bone, or liver tissue, exposing surrounding cells to continuous, high-energy ionizing radiation. This dramatically increases the risk of fatal cancers and systemic radiation poisoning. Because of these extreme risks, the import, export, and transfer of plutonium are strictly controlled under international treaties and federal laws, including the Atomic Energy Act.
Thallium
Thallium is a soft, malleable heavy metal that is highly toxic to human biology. Often referred to as the "poisoner’s poison" because of its colorless, odorless, and tasteless properties when dissolved in water, thallium interferes with cellular potassium absorption, leading to multi-organ failure, severe neurological damage, alopecia, and death.

The U.S. Environmental Protection Agency (EPA) and the Department of Transportation (DOT) classify thallium as a hazardous material subject to stringent transport and disposal protocols.
Seized Contraband and Digital Evidence
- Ammunition & Explosives: Investigators seized a box of Federal American Eagle .45-caliber ammunition alongside six unregistered firearms. The explosive powders recovered were chemically volatile and stored in residential conditions without safety permits.
- Digital Forensic Data: Forensic imaging of Miller’s laptop and mobile phone confirmed the presence of CSAM. The metadata indicated ongoing access, downloading, and possession of these files up to the eve of his arrest.
Official Responses
The guilty plea has elicited strong reactions from federal prosecutors and regulatory agencies, who emphasized the intersection of national security threats and exploitative crimes in this case.
Department of Justice Statement
The U.S. Attorney’s Office for the District of Massachusetts emphasized the severity of Miller’s actions in bypassing critical national security protocols.
"The defendant operated an illicit, unregulated marketplace from his home, importing dangerous radioactive materials from an adversarial nation and distributing them through the public mail system," prosecutors stated. "By shipping radioactive plutonium and highly toxic thallium to dozens of individuals globally, the defendant showed a complete disregard for public safety and international law, compounded by his continued possession of highly exploitative child sexual abuse material."
FBI Boston and Joint Terrorism Task Force
The FBI’s Boston Field Office, which led the physical raid and investigation alongside hazardous materials experts, underscored the danger posed by the unregulated distribution of nuclear isotopes.
Agents noted that the possession of explosive materials and firearms by a previously convicted felon—especially one with a prior conviction for possessing explosive devices—represents an acute domestic security threat. The FBI confirmed that specialized teams were deployed during the April 2025 raid to safely secure, test, and transport the radioactive and explosive compounds found in Miller’s home.
Postal Inspection Service Action
The U.S. Postal Inspection Service issued a warning regarding the exploitation of public infrastructure for trafficking hazardous materials. Representatives noted that the USPS employs advanced screening and detection systems, but acknowledged that decentralized, small-scale shipments of elemental isotopes present unique detection challenges. The agency reiterated
that shipping prohibited hazardous substances like plutonium and thallium through the mail constitutes a federal felony that carries severe statutory penalties.
Implications
The conviction of Jacob D. Miller highlights critical vulnerabilities in e-commerce, global logistics, and national security.

National Security and the Nuclear Black Market
The fact that a private citizen in Massachusetts could systematically import plutonium from Russia over a four-year period—amidst historically high geopolitical tensions and strict export controls—exposes a significant gap in international customs and border protection screening.
While the quantities sold to "Collect The Periodic Table" customers were likely small elemental samples, the unregulated circulation of plutonium is a major concern for non-proliferation officials. Even small amounts of radioactive isotopes can be gathered to construct radiological dispersal devices, commonly known as "dirty bombs."
Vulnerabilities in E-Commerce and Postal Systems
The case exposes the difficulties online marketplaces face in monitoring the sale of hazardous materials. Platforms like Bonanza and direct domain registrars are often used by illicit sellers who disguise toxic chemicals or radioactive elements as benign educational or novelty items.
Furthermore, the reliance on the USPS to deliver these materials puts postal workers, sorting facility staff, and delivery personnel at risk of accidental exposure to toxic thallium dust or radiation.
Legal and Sentencing Outcomes
Miller’s sentencing on January 21 will address a complex set of federal guidelines.
- The charge of importing nuclear material without authority carries severe statutory maximum penalties, reflecting its national security implications.
- Felon in possession of firearms, ammunition, and explosives charges carry substantial prison terms, especially given Miller’s 2004 conviction for possessing explosive devices.
- The possession of child pornography charge carries mandatory minimum sentences and requires a period of supervised release that could extend to a lifetime.
Given his prior criminal record and the combination of radiological trafficking and child exploitation charges, prosecutors are expected to seek a lengthy federal prison sentence.
