Buffalo Man Gets Nearly 20 Years for Fentanyl Conspiracy

Calvin Elston Jr., 41, of Buffalo, NY, is headed to federal prison for 235 months after being sentenced in a sprawling fentanyl conspiracy that flooded Western New York with deadly synthetic opioids. U.S. Attorney James P. Kennedy, Jr. confirmed the sentencing, handed down by U.S. District Judge Richard J. Arcara, marking the final disposition in a case that exposed a criminal network built on forged prescriptions and cold cash.

Between July 2013 and May 2015, Elston conspired with ten others—including former nurse practitioner Brandon Coburn—to distribute fentanyl, oxymorphone, oxycodone, and amphetamines, all Schedule II controlled substances. Elston obtained prescriptions under his own name and through recruited individuals who never saw Coburn for medical treatment. The operation was a fraud from start to finish: no patients received care, only scripts that turned into street profits.

Elston and co-defendant Jennifer L. Courton orchestrated a ring of runners—including Rodney Courton, John Davis, Samuel Nappo, Tashaira Vazquez, Terrance Williams, Johanna Sanchez-Rodriquez, and Luis Diaz—who cashed in by submitting prescriptions at pharmacies. Each participant was paid for their role, with Coburn pocketing money for every illegitimate prescription written. Over 25 months, Coburn issued 253 prescriptions with zero medical justification.

The Drug Enforcement Administration, under Special Agent-in-Charge Ray Donovan of the New York Field Division, led the investigation that dismantled the ring. The probe revealed a chillingly efficient pipeline: medical credentials exploited, desperate people paid to play patients, and lethal drugs funneled into communities already reeling from the opioid crisis.

All ten defendants have now been sentenced. Coburn received 108 months. Jennifer Courton got 180 months. Others faced time ranging from 18 to 57 months. Elston, as a key operative in the conspiracy, drew the second-longest sentence. The case underscores how healthcare professionals and organized crime can merge in the darkest corners of the drug trade.

This sentencing closes the book on one of Buffalo’s most brazen pharmaceutical fraud rings. But with fentanyl still killing thousands nationwide, law enforcement warns that cases like Elston’s are not anomalies—they’re symptoms of a deeper epidemic. The DEA vows to keep targeting supply chains, one pill, one prescription, one kingpin at a time.
