Brownsville Pyrotechnician Admits to Illegal Explosives Operation

BROWNSVILLE, MINNESOTA – Kenneth Ray Miller, 58, of Brownsville, is facing federal sentencing after admitting today to a years-long scheme manufacturing and selling dangerous explosive materials across state lines. Miller pleaded guilty before Judge Patrick J. Schiltz in Minneapolis, U.S. District Court, effectively ending a case that began with a tip-off sparked by a harmless-seeming magazine article.

The case unraveled in the spring of 2019 when the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) received word of a Popular Science feature detailing Miller’s pyrotechnic hobby on his Brownsville property. What initially appeared as an eccentric pastime quickly turned sinister as investigators discovered Miller’s prior felony convictions – convictions that explicitly barred him from possessing firearms and engaging in the manufacture and sale of explosive materials. He wasn’t just building fireworks; he was operating an illegal, unregulated explosives business.

According to court documents filed in the case, between 2013 and March 3, 2020, Miller manufactured and distributed smoke-generating devices containing electric igniters (commonly known as electric matches) and a highly volatile chlorate explosive mixture. These weren’t simple smoke bombs. These devices were sold to customers nationwide, all without the necessary licenses, permits, or any authorization whatsoever from the ATF. Miller brazenly skirted federal regulations, putting public safety at risk for profit.

The investigation revealed a sophisticated, albeit illegal, operation. Miller wasn’t simply tinkering in his garage. He was actively manufacturing and selling these explosive components, effectively becoming an unlicensed dealer in dangerous materials. The ATF’s investigation uncovered a network of customers who unwittingly purchased potentially unstable and illegally produced devices. The full scope of the damage and potential misuse of these materials is still being assessed.

Federal prosecutors, led by Assistant U.S. Attorney Emily A. Polachek, built a solid case based on evidence gathered through meticulous investigation. The ATF was supported by a multi-agency task force including the Houston County Sheriff’s Office, the St. Paul Police Department, the U.S. Environmental Protection Agency, the Minnesota Department of Natural Resources, and the Minnesota Department of Public Safety (State Fire Marshal). The collaborative effort highlighted the seriousness of the threat posed by Miller’s operation.

While MILLER’s guilty plea closes this chapter, his sentencing date remains unconfirmed. The Grimy Times will continue to follow this case and provide updates as they become available. Given the nature of the charges – manufacturing and dealing in explosive materials – a substantial prison sentence is widely anticipated. This case serves as a stark reminder that even seemingly harmless hobbies can quickly escalate into serious federal crimes, and that authorities are actively working to dismantle illegal explosives operations nationwide.
