ROANOKE Va. (WFXR) — A man pleaded guilty on Friday to a federal firearm offense in connection with the deadly 2019 shooting of a teenager in Roanoke, even though he was previously acquitted in state court of murder and other charges from the same incident.

More than three years later, on Friday, July 15, Demarcus Shaiquan Glenn, 23, of Roanoke “pled guilty in federal court to one count of possessing, brandishing, and discharging a firearm in furtherance of a drug trafficking crime,” according to the U.S. Attorney’s Office for the Western District of Virginia.

Glenn is expected to be sentenced to 12 years in federal prison under a plea agreement, authorities say.

“Drug dealers with firearms should take heed: You cannot shoot someone during a drug deal and then claim self-defense when you are carrying that firearm in furtherance of drug trafficking, a federal crime with a 10-year mandatory minimum,” U.S. Attorney Christopher R. Kavanaugh said. “The cornerstone of keeping our communities safe is prosecuting anyone who discharges a firearm while participating in the drug trafficking trade, and my Office will continue to prioritize and seek federal charges for anyone who does so within the Western District of Virginia.”

The charges are in relation to the deadly shooting of 16-year-old Tyler Polumbo in southwest Roanoke on May 31, 2019.

Court documents show that 16-year-old “T.P.” contacted Glenn about buying two ounces of marijuana, during which time Glenn agreed to the sale and agreed to meet him at “T.P.’s” Denniston Avenue home with $300. However, when Glenn showed up at “T.P’s” home, Glenn pulled out a gun and shot and killed the teenage boy.

On June 11, 2019, police announced they arrested then-20-year-old Glenn in northwest Roanoke.

However, on Oct. 20, 2021, officials say Glenn was found not guilty of the following charges, claiming self-defense:

  • One count of first-degree murder
  • One count of attempted armed robbery
  • Two counts of use of a firearm in the commission of a felony

During the state jury trial, Glenn testified that he was carrying a loaded gun when he met up with “T.P.,” going on to say that it was for protection while he was selling drugs. While under oath, Glenn admitted to shooting “T.P.” during the drug deal.

According to the Department of Justice, “Federal law prohibits drug dealers from possessing, brandishing, and discharging a firearm in furtherance of a drug trafficking crime.”

“The outcome of this investigation is a direct and positive result of state, local, and federal agencies working together to address gun violence in the City of Roanoke,” Roanoke Police Chief Sam Roman said. “Though Glenn was acquitted on charges from our jurisdiction, our public safety partners at the federal level were able to open an investigation and work with our officers and detectives on appropriate, federal charges for this offense.”
