DENVER – The United States Attorney’s Office for the District of Colorado announces that Derris Mayberry, 37, of Denver, was sentenced to 110 months in federal prison after being convicted by federal juries in two trials of one count of Possession with Intent to Distribute Fentanyl and one count of Felon in Possession of a Firearm.

According to the facts established at the trials, on the evening of March 22, 2024, a woman approached an officer conducting surveillance for an undercover operation and offered the officer “dope.”  She then told the officer that she knew someone who could get “blues,” meaning fentanyl pills.  The woman ultimately led undercover police officers to an alley near the Colorado State Capitol where Mayberry was waiting.  An audio recording captured the undercover officer negotiating the price and amount of fentanyl pills.  The officers then observed the woman make a hand-to-hand exchange with Mayberry, immediately after which the woman handed four fentanyl pills to the undercover officer in exchange for $20.  Law enforcement contacted Mayberry shortly thereafter at a bus stop only feet away from where the deal had taken place.  During a pat down, law enforcement found a loaded .22 caliber revolver in his shorts pocket.  Mayberry had previously been convicted of multiple felonies and, therefore, was prohibited from possessing the loaded revolver.  During a search incident to his arrest, law enforcement found additional fentanyl pills and the $20 used by the undercover officer to purchase the drugs.

“Illicit fentanyl destroys lives,” said Acting U.S. Attorney J. Bishop Grewell. “Our office will continue to prioritize putting fentanyl traffickers behind bars.”

“Felons illegally possessing firearms and distributing deadly drugs like fentanyl pose a serious and immediate threat to public safety,” said ATF Acting Special Agent in Charge Chris Ashbridge. “We are grateful for our local and federal partners who are unified in our commitment to pursue these violent criminals and hold them accountable for their actions.”

“What began as great, proactive police work ended with an armed dealer of dangerous narcotics being sentenced to prison to a lengthy term,” said Denver Police Chief Ron Thomas. “The Denver Police Department, in partnership with the Bureau of Alcohol, Tobacco, Firearms, and Explosives and U.S. Attorney’s Office, remain committed to stopping the availability of dangerous drugs in Denver.”

United States District Judge Daniel D. Domenico presided over the sentencing. The Denver Police Department VICE unit and the Bureau of Alcohol, Tobacco, Firearms, and Explosives handled the investigation.  Assistant United States Attorneys Theodore O’Brien and Celeste Rangel handled the prosecution.
