Jonathan Ernspiker, a 42-year-old resident of Louisville, Kentucky, has been sentenced to 15 years in federal prison followed by six years of supervised release. The sentencing follows his conviction for firearms trafficking, distribution of methamphetamine, possession of a firearm in furtherance of a drug trafficking crime, and possession of a firearm by a convicted felon. Authorities said Ernspiker conspired to sell 18 firearms and about 58 grams of methamphetamine to a confidential law enforcement source on November 20, 2024.
The announcement was made by U.S. Attorney Kyle G. Bumgarner for the Western District of Kentucky and Special Agent in Charge John Nokes from the ATF Louisville Field Division.
United States Attorney Kyle Bumgarner stated, “Ernspiker’s 15-year sentence demonstrates that the United States Attorney’s Office and ATF have absolutely no tolerance for drug trafficking and illegal firearms trafficking. Drug trafficking and illegal firearms trafficking significantly contribute to the violence plaguing our community. Hopefully, Ernspiker’s sentence sends a strong deterrent message to others engaged in or contemplating engaging in similar conduct.”
ATF Special Agent in Charge John Nokes added, “Firearms trafficking undermines the basic safeguards that are in place to keep weapons out of the hands of criminals. When combined with the distribution of dangerous narcotics such as methamphetamine, it creates an environment that threatens the safety and stability of communities throughout the Commonwealth. Jonathan Ernspiker’s significant prison sentence sends a clear message: the ATF, the U.S. Attorney’s Office, and our local law-enforcement partners remain fully committed to aggressively pursuing and prioritizing investigations of this nature.”
Due to prior felony convictions in Bullitt County Circuit Court—including charges for being a convicted felon in possession of a firearm (2017), possession and manufacturing methamphetamine (2013), fleeing police (2013), criminal mischief (2008), and other drug-related offenses—Ernspiker was prohibited from possessing firearms at the time of his arrest.
Federal sentences do not allow parole.
The case was investigated by the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF). Assistant U.S. Attorney Joshua R. Porter prosecuted with support from Paralegal Specialist Adela Alic.
This prosecution is part of Operation Take Back America, an initiative led by the Department of Justice aimed at combating illegal immigration, eliminating cartels and transnational criminal organizations (TCOs), and reducing violent crime nationwide.
