ST. LOUIS – A previously convicted felon from St. Louis County was sentenced in federal court Tuesday for a 2024 drug robbery and carjacking.

Prosecutors with the U.S. Attorney’s Office for the Eastern District of Missouri said Walter C. Moore, 20, committed the robbery on April 25 outside his home.

In February 2025, Moore pleaded guilty to being a felon in possession of a firearm, possession of a machine gun, robbery, carjacking, and brandishing a firearm in furtherance of a crime of violence.

Police and prosecutors said Moore arranged to buy $900 of Oxycodone from the victim, who drove to Moore’s home in her 2014 Mazda 6. The seller invited Moore to sit in her car to complete the sale. Moore then pulled out a handgun from a black bag, grabbed the Oxycodone pills, and ordered the victim from her car.

Moore got in the driver’s seat and left while the victim ran to a nearby home to seek help.

The victim’s phone was still in the Mazda, which St. Louis County police used to locate the vehicle. Police claim Moore tried to run away on foot but was apprehended after a brief chase.

Police searched Moore’s black bag and found the Oxycodone pills, a Glock pistol equipped with a switch, an extended magazine, and a laser sight.

Law enforcement eventually searched Moore’s phone and discovered several pictures of Moore holding multiple firearms. As a convicted felon, Moore is not allowed to own or possess a gun.

In the aforementioned case, Moore drove a stolen car to his girlfriend’s home in University City in June 2023 and fired a gun into the air outside the residence. He led police on car chase, which he streamed on Instagram, and texted a death threat to his girlfriend. After being arrested and booked, police said Moore called a friend and said that he’d kill his girlfriend once he got out of jail.

On March 18, 2024, Moore was convicted of unlawful use of a weapon, first-degree harassment, tampering with a motor vehicle, and resisting arrest.

A U.S. District Court judge sentenced Moore to 15 years in federal prison for the robbery and carjacking.
