A Jamestown man has pleaded guilty for selling fentanyl in the city.

U.S. Attorney Michael DiGiacomo announced that 48-year-old Joseph Thayer pleaded guilty to narcotics conspiracy, which carries a mandatory minimum penalty of 10 years in prison and a maximum of life.

Assistant U.S. Attorneys Joshua A. Violanti and Louis A. Testani, who are handling the case, stated that Thayer conspired with his roommate, Justin Yuchnitz, to sell heroin and fentanyl supplied by Jaquez Thomas. Thayer was aware that Thomas’s source of supply was Joseph Zaso. During the conspiracy, Yuchnitz amassed a $4,500 dollar debt to Thomas and Zaso, which Thayer tried to assist Yuchnitz in paying off.

Thayer is responsible for distributing at least 462 grams of fentanyl.

Defendants Yuchnitz and Zaso were previously convicted and are awaiting sentencing. Charges remain pending against defendant Thomas.

This case is part of Operation Take Back America, a nationwide initiative that marshals the full resources of the Department of Justice to repel the invasion of illegal immigration, achieve the total elimination of cartels and transnational criminal organizations, and protect our communities from the perpetrators of violent crime. Operation Take Back America streamlines efforts and resources from the Department’s Organized Crime Drug Enforcement Task Forces and Project Safe Neighborhood.

The plea is the result of an investigation by the Jamestown Police Department, under the direction of Chief Timothy Jackson, the Drug Enforcement Administration, under the direction of Special Agent-in-Charge Frank A. Tarentino III, New York Field Division, and the Chautauqua County Sheriff’s Office, under the direction of Sheriff James Quattrone.

Sentencing is scheduled for Feb. 24 at 10 a.m. before Judge Sinatra.
