Two Major Drug Trafficking Convictions Result in Lengthy Prison Sentences in Adams County

Brighton, CO – District Attorney Brian Mason announced today two significant drug trafficking convictions and prison sentences secured by the District Attorney’s Office Drug Trafficking Unit and its investigative partners.  

24CR1171 – Alfonso Duran 
Following a months-long investigation by the DEA Colorado Springs Office and the Southern Colorado Drug Task Force, Alfonso Duran, 44, was arrested and charged in connection with large-scale cocaine distribution in the Aurora area. 

Investigators conducted multiple controlled purchases of cocaine from Duran between August 2023 and March 2024. On March 21, 2024, Duran delivered approximately 5 ounces of cocaine to an undercover investigator. 

24CR1349 – Alfonso Duran 
On April 22, 2024, Duran agreed to sell 20 ounces of cocaine to an undercover investigator. When he arrived he was placed under arrest and a search of his vehicle and residence resulted in the seizure of approximately 2 kilograms of suspected cocaine, along with digital scales, packaging materials, prepaid phones, and records consistent with drug trafficking. 

On September 26, 2025, Duran pleaded guilty to Possession with Intent to Manufacture or Distribute a Controlled Substance (DF1) and Possession with Intent to Manufacture or Distribute a Controlled Substance (DF2). On January 9, 2026, Adams County District Court Judge Mark Warner sentenced him to 16 years in the Colorado Department of Corrections. Duran has multiple prior felony drug convictions.  

25CR2158 – Kenney Pavon-Espinal 
In July 2025, Kenney Pavon-Espinal, 27, was arrested at Me Gusto Es 2 Restaurant in unincorporated Adams County while attempting to deliver 100 counterfeit oxycodone pills containing fentanyl to undercover detectives. 

The arrest followed a month-long investigation by the North Metro Task Force during which Pavon-Espinal allegedly sold over 50 grams of counterfeit pills and more than 11 grams of powdered fentanyl in Thornton and surrounding areas. The controlled purchases were arranged with undercover officers, and all seized substances tested positive for fentanyl, a powerful synthetic opioid known to be highly addictive and potentially lethal even in very small amounts. 

On January 9, 2026, Pavon-Espinal pleaded guilty to Distribution of a Controlled Substance (DF1). Adams County District Court Judge Arturo Hernandez sentenced him to 8 years in the Colorado Department of Corrections. 

"These convictions reflect our ongoing commitment to removing dangerous drugs from our communities and holding drug traffickers accountable,” said District Attorney Brian Mason. “Cocaine, fentanyl, and counterfeit pills pose a real and immediate threat to the lives of our families and neighbors. We will continue working with our law enforcement partners to dismantle these operations and get these dangerous drug dealers off our streets." 

These cases were prosecuted by Senior Deputy District Attorney Mike Freeman of the 17th Judicial District Attorney’s Office Drug Trafficking Unit. 

*While both cases involve serious narcotics offenses, they are entirely unrelated; they are being announced at the same time due to their resolution dates.
