Eastern Jackson County Man Sentenced for Fentanyl Trafficking, Machine Gun Conversion Devices

KANSAS CITY, Mo. - An Oak Grove, Mo., man was sentenced in federal court today for his role in a fentanyl trafficking conspiracy and possession of machine gun conversion devices.

Kal J. Nay, 22, was sentenced by U.S. District Judge Beth Phillips to 3 years in federal prison without parole.

His co-defendant, Robert J. Turnage, 22, was sentenced on Sept. 24, 2025, to 4 years in federal prison without parole for his role in the fentanyl trafficking conspiracy.

On Oct. 9, 2025, Nay pleaded guilty to conspiracy to distribute fentanyl and possession of machine guns.

Between May 2, 2024, and June 11, 2024, the Jackson County Drug Task Force utilized a Confidential Informant to purchase "M30" pills, which contained fentanyl, from Nay and Turnage. The Confidential Informant purchased 10 pills from Nay on May 2, 40 pills from Nay on May 23, and 20 pills from Nay and Turnage on June 11. On June 18, 2024, members of the Jackson County Drug Task Force were granted a state search warrant to search Nay's residence in Oak Grove. Investigators seized 6 machine gun conversion devices, also known as "switches," that were 3D printed from a 3D printer which was found in the residence. Nay admitted to investigators that he sold fentanyl pills and that he made the "switches" with his 3D printer.

This case was prosecuted by Assistant U.S. Attorney Jessica Jennings. It was investigated by the Jackson County Drug Task Force and the Bureau of Alcohol, Tobacco, Firearms and Explosives.
