Derrick Carl Andrew Chatman, Firearms Trafficking, Oklahoma 2024

TULSA, Okla. – A Broken Arrow man has been indicted for allegedly selling a machinegun conversion device to a minor while serving a firearm and drug sentence.

Derrick Carl Andrew Chatman, 24, is charged with Possession of a Firearm by Person Under Indictment, Transfer or Possession of a Machinegun, and Firearms Trafficking.

The unsealed complaint alleges that in July, the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) was contacted by the Tulsa Police Department about recovering a firearm with an attached machinegun conversion device commonly known as a “switch.” A parent found the gun and ammunition in their juvenile’s bedroom. With the parents’ permission, the juvenile spoke with law enforcement and disclosed that he purchased the firearm at a gun show at the fairgrounds.

While at the gun show, the juvenile met a man he could buy a switch from, later identified as Chatman, who sold the switch to the juvenile. Video surveillance from the gun show also shows Chatman purchasing a firearm.

During a search of Chatman’s home, law enforcement allegedly found a gun, several rounds of ammunition, and a box with a shipping label from China that contained firearm switches.

Court records show that Chatman was charged in July 2024 with two counts of unlawful possession of a controlled drug with intent to distribute, possession of a firearm while committing a felony, and other crimes. In December 2024, Chatman pleaded guilty, was sentenced, and remains under the State’s supervision.

The ATF and the Tulsa Police Department are investigating the case. Assistant U.S. Attorney Aaron Jolly is prosecuting the case.

A criminal complaint is merely an allegation. The defendant is presumed innocent until proven guilty beyond a reasonable doubt in a court of law.
