DENVER — The United States Attorney’s Office for the District of Colorado announced Friday that a convicted fentanyl dealer who was arrested by undercover officers near the Colorado State Capitol last year has been sentenced to more than nine years in federal prison.
Derris Mayberry, a 37-year-old resident of Denver, has been sentenced to spend 110 months in federal prison following his February 2025 convictions in two trials for charges related to possession with intent to distribute fentanyl and being a felon in possession of a firearm.
Mayberry was arrested on March 22, 2024, in an alley near the Colorado State Capitol during an undercover operation, according to a news release.
Prosecutors stated that a woman led police to Mayberry, where officers witnessed an exchange and later apprehended him at a nearby bus stop.
Police said Mayberry had a loaded revolver at the time of his arrest. They also found additional fentanyl pills and the $20 from the drug deal.
Denver Police Chief Ron Thomas expressed satisfaction with the outcome, stating, “What began as great, proactive police work ended with an armed dealer of dangerous narcotics being sentenced to prison to a lengthy term,” in a news release.
Thomas stated that the Denver Police Department remains “committed to stopping the availability of dangerous drugs in Denver.”
