Derris Mayberry, a 37-year-old resident of Denver, has been sentenced to 110 months in federal prison. The sentence follows his conviction by federal juries on charges of possession with intent to distribute fentanyl and being a felon in possession of a firearm.
The events leading to the conviction occurred on March 22, 2024. A woman approached an officer involved in an undercover operation and offered drugs. She informed the officer about someone who could supply fentanyl pills, known as "blues." This led officers to an alley near the Colorado State Capitol where Mayberry was present. An audio recording documented the negotiation between Mayberry and the undercover officer regarding the price and quantity of fentanyl pills. Following this exchange, law enforcement apprehended Mayberry at a nearby bus stop. During a pat-down search, officers discovered a loaded .22 caliber revolver in his pocket. Due to previous felony convictions, Mayberry was prohibited from possessing firearms. Further searches revealed additional fentanyl pills and $20 used in the drug transaction.
Acting U.S. Attorney J. Bishop Grewell stated, “Illicit fentanyl destroys lives,” emphasizing their focus on incarcerating fentanyl traffickers.
ATF Acting Special Agent Chris Ashbridge remarked on the threat posed by felons illegally possessing firearms and distributing drugs like fentanyl, expressing gratitude for collaborative efforts with local and federal partners.
Denver Police Chief Ron Thomas praised the proactive police work that led to removing an armed narcotics dealer from the streets, highlighting ongoing efforts with partner agencies to curb dangerous drug availability in Denver.
The sentencing was overseen by United States District Judge Daniel D. Domenico. The investigation involved collaboration between the Denver Police Department VICE unit and the Bureau of Alcohol, Tobacco, Firearms, and Explosives. The prosecution was managed by Assistant United States Attorneys Theodore O’Brien and Celeste Rangel.
