Massachusetts Man Indicted for Illegally Possessing Ammunition and Explosives

Press Release

Radioactive material and other hazardous substances, including plutonium, seized from defendant's residence

BOSTON -A Hadley, Mass. man has been indicted by a federal grand jury in Springfield for allegedly possessing ammunition and explosives after being convicted of a crime punishable by more than one year in prison.

Jacob D. Miller, 43, was indicted on one count of being a felon in possession of ammunition and one count of being a felon in possession of explosive materials. Miller was arrested on April 9, 2025 on a criminal complaint charging him with being a felon in possession of ammunition. He remains in federal custody as the Court has taken the matter of pretrial detention under advisement.

On April 8, 2025, following the execution of a search warrant at Miller's Hadley residence, a box of approximately 50 rounds of Federal brand, American Eagle .45 auto, 230 grain ammunition were found in a bedside table, in addition to six firearms found in a hallway safe. Additionally, explosive materials, hazardous chemicals and radioactive materials, including plutonium, were found in Miller's home.

According to evidence presented at a subsequent detention hearing, Miller has exhibited a long-standing and unlawful obsession with explosives, dangerous chemicals and radioactive substances dating back to at least 2002. That year, during a search of Miller's prior residence, blasting caps, bomb-making instructions, military equipment including an apparent rocket launcher, a homemade pipe bomb and a video depicting the Miller igniting several improvised explosive devices, including one that he referred to as a "hand grenade," were recovered. Miller was later convicted in state court of possessing those devices.

According to court records, while still on probation in 2014, the Massachusetts Radiation Control Program issued a cease-and-desist letter to Miller after discovering he was selling depleted uranium on eBay. Despite Miller's claims that he had ceased such activity, he allegedly launched his own online business called "Collect the Periodic Table" in 2017, through which he marketed and sold radioactive materials, including Plutonium-239 allegedly derived from Cold War-era Soviet smoke detectors. It is further alleged that between June and October 2023, Miller conducted at least five PayPal transactions for the sale of plutonium. Additional records of plutonium sales were allegedly recovered from his residence during the 2025 search.

In 2023, Miller allegedly directed an associate to purchase five pounds of hazardous black powder and have it shipped to his residence in Hadley. Witnesses allegedly reported that Miller used the powder to ignite a fireball and detonate a dishwasher in his backyard during gatherings at his residence. During the April 2025 search, remnants of the shipment, including multiple bottles of explosive powder, one of which had been opened, were found.

According to court records, authorities cataloged and secured numerous other potentially hazardous substances found at Miller's residence - including fuels, alkali metals, oxidizers, acids and toxic elements such as arsenic. The Massachusetts Department of Environmental Protection (MassDEP) warned that these substances posed a serious risk to occupants, first responders and the public in the event of a fire, accident, or natural disaster. The Court has since ordered that MassDEP conduct a comprehensive safety evaluation and oversee the removal of hazardous materials from the residence.

According to the charging documents, on Feb. 9, 2004, Miller was convicted in two of in Hampshire Superior Court of one count of possession of child pornography and sentenced to seven years of probation. Miller was also convicted in a separate case in Hampshire Superior Court of two counts of possession of an explosive device and sentenced to two and one-half years in jail and 10 years of probation. As a result of those convictions, Miller is prohibited under federal law from possessing ammunition, firearms and explosives.

The charges of being a felon in possession of ammunition and explosives each provide for a sentence of 15 years in prison, three years of supervised release and a fine of up to $250,000. Sentences are imposed by a federal district court judge based upon the U.S. Sentencing Guidelines and statutes which govern the determination of a sentence in a criminal case.

United States Attorney Leah B. Foley and James Crowley, Acting Special Agent in Charge of the Federal Bureau of Investigation, Boston Division made the announcement today. Valuable assistance was provided by the Hadley Police Department and the Massachusetts State Police. Assistant U.S. Attorney Steven H. Breslow of the Springfield Branch Office is prosecuting the case.

The details contained in the charging documents are allegations. The defendant is presumed innocent unless and until proven guilty beyond a reasonable doubt in a court of law.
