For Immediate Release
U.S. Attorney's Office, District of Colorado

DENVER – The United States Attorney’s Office for the District of Colorado announces Tanya Bui, age 24, of Littleton has been sentenced to 10 years and 10 months in federal prison. She pleaded guilty to possession of fentanyl with intent to distribute, as well as possession of a firearm in furtherance of a drug trafficking offense. 

According to facts contained in the plea agreement, on January 27, 2021, investigators searched the defendant’s Littleton residence as part of an investigation of a homicide that occurred in Denver in August of 2020. The defendant’s bedroom was located in the basement of the residence and was searched. In the nightstand drawer next to her bed was a clear plastic bag with 692 fentanyl pills. On top of the defendant’s dresser was a loaded magazine. In the defendant’s closet were jars of marijuana, a loaded firearm, a scale with apparent drug residue, plastic baggies, a large trash bag containing marijuana, two boxes of ammunition and $6,825 in cash. In addition, a search warrant was obtained for her social media accounts, which showed she was using her juvenile brother to aid her in distributing marijuana, fentanyl and firearms to various customers, including juveniles.

Chief Judge Philip A. Brimmer sentenced Bui to 130 months in prison on July 15, 2022.

“This defendant’s outrageous actions, including dealing drugs to juveniles, are worthy of a lengthy prison sentence,” said U.S. Attorney Cole Finegan. “We appreciate the diligent work of our partners at the ATF and the Denver Police Department.”

“Firearms and Fentanyl are the tools of violent crime. This investigation was not possible without our local law enforcement partners, and we are grateful to the prosecutors in acquiring a lengthy sentence,” said ATF Special Agent in Charge David S. Booth.

This case was investigated by the Bureau of Alcohol, Tobacco, Firearms and Explosives and the Denver Police Department’s Homicide Unit. The case was prosecuted by Assistant United States Attorney Celeste Rangel.
