Man Admits Being Caught with MCD-Equipped Guns Three Times in St. Louis

ST. LOUIS - A man caught three times with firearms equipped with devices that convert them into machine guns pleaded guilty Wednesday to gun charges.

Deverin Myers, 22, of University City, pleaded guilty to two counts of possession of a machine gun and one count of receiving a firearm while under indictment.

On Aug. 21, 2024, St. Louis Metropolitan Police Department detectives spotted Myers, who had a pistol equipped with a red machinegun conversion device (MCD) sticking out of his pocket, and other armed men in the 2900 block of James "Cool Papa" Bell Avenue. Myers was arrested and police recovered a Shadow Systems MR920 .40 S&W caliber pistol, loaded with 24 rounds of ammunition. Myers knew that he had an MCD, as he had arrested in possession of an MCD in 2023 and was charged in St. Louis Circuit Court with possession of an illegal weapon in 2024. An MCD converts a semi-automatic firearm into a fully automatic firearm.

On Aug. 18, 2025, SLMPD officers observed a blue Audi parked in front of a vacant property in the same block of James "Cool Papa" Bell Avenue. When officers approached, the vehicle sped off, violating stop signs and traffic signals. The Audi became disabled in the 3400 block of North 22nd Street and the driver and Myers ran away. Myers discarded a micro-Draco pistol as he ran, and officers later found a Glock 19 pistol equipped with an MCD and loaded with 35 rounds of ammunition in the same location. The Draco pistol had been bought five days earlier, after Myers was indicted and arraigned on the 2024 charge.

At sentencing, Myers faces up to 10 years in prison for the machine gun charges and up to five years in prison on the other gun charge.

The St. Louis Metropolitan Police Department and the Bureau of Alcohol, Tobacco, Firearms and Explosives investigated the case. Assistant U.S. Attorney Jennifer Szczucinski is prosecuting the case.
