Lawton Man Sentenced to Serve More Than Five years in Federal Prison for Possessing Machinegun Conversion Device (DOJ)

OKLAHOMA CITY - JEREMIAH ALEXANDER DEARING, 21, of Lawton, has been sentenced to serve 70 months in federal prison for unlawful possession of a machinegun, announced U.S. Attorney Robert J. Troester.

According to public records, on October 9, 2024, Dearing participated in a recorded video jail call with an inmate at the Grady County Jail. During that call, officers with the Lawton Police Department (LPD) observed Dearing display an AK47-style pistol and flash multiple gang signs. As Dearing's age prohibited him from legally carrying such a firearm under Oklahoma state law, LPD detectives sought and obtained a search warrant for his residence. Law enforcement executed that warrant and discovered five firearms in Dearing's bedroom, including a privately manufactured firearm that did not have a serial number. All of the firearms were chamber-loaded and equipped with high-capacity magazines. Officers also seized a machinegun conversion device (MCD). When installed, the MCD converts a semi-automatic weapon into a fully automatic machinegun. Law enforcement also recovered approximately 92 fentanyl pills from the residence.

On December 3, 2024, a federal Grand Jury charged Dearing with unlawful possession of a machinegun. Dearing pleaded guilty on February 11, 2025, and admitted to possessing a machinegun.

At the sentencing hearing on August 22, 2025, U.S. District Judge Patrick R. Wyrick sentenced Dearing to serve 70 months in federal prison, followed by three years of supervised release. In announcing his sentence, Judge Wyrick noted the significant public safety concern posed by Dearing's conduct and the need to promote respect for the law.

This case is the result of an investigation by the Bureau of Alcohol, Tobacco, Firearms and Explosives and the Lawton Police Department. Assistant U.S. Attorney Danielle M. Connolly prosecuted the case.

This case is part of Project Safe Neighborhoods (PSN), a program bringing together all levels of law enforcement and the communities they serve to reduce violent crime and gun violence, and to make our neighborhoods safer for everyone. This case is also part of "Project Switch Off," the Western District of Oklahoma's local implementation of PSN. "Project Switch Off" targets illegal machinegun conversion devices to address the significant danger these illegal devices present and to remove them from our streets.
