OKLAHOMA CITY, OK – Collin Shane Kirby, 21, of Oklahoma City, and Shane Michael Burgess, 24, of Mustang, Oklahoma, have both pleaded guilty to distributing a controlled substance analogue. 

According to public records, on December 12, 2025, Kirby sold pills to Burgess that contained N-Propionitrile Chlorphine, a synthetic opioid known as cychlorphine. That same day, Burgess resold the pills he bought from Kirby to another individual. Court records show the individual died as a result of using the cychlorphine distributed by Burgess and Kirby.

In July and August, Kirby and Burgess were charged by separate superseding informations with distribution of a controlled substance analogue. Both have since pleaded guilty and admitted their roles in distributing the cychlorphine that ultimately resulted in at least one individual’s death. Kirby also specifically admitted to distributing cychlorphine to another individual, a minor, on February 7, 2026.

At sentencing, Burgess and Kirby each face up to 20 years in federal prison and fines of up to $1,000,000.

These cases are the result of investigations by the Drug Enforcement Administration Oklahoma District Office and the Oklahoma Bureau of Narcotics and Dangerous Drugs.
