PORTSMOUTH — While on parole for Portsmouth drug and sex-assault charges, Grant Michallyszyn was staying in a Nashua motel where he was trafficking fentanyl and possessed two handguns, U.S. Attorney Scott Murray announced.

Michallyszyn, 22, pleaded guilty Monday to possession of fentanyl with intent to distribute and "possession of a firearm in furtherance of a drug trafficking crime," both federal crimes, Murray announced.

"The illegal sale of fentanyl poses a serious and well-known risk to public health and safety," Murray stated. "When fentanyl dealers use firearms to further sales, the danger to the public is greatly increased. Accordingly, the aggressive prosecution of armed fentanyl dealers will continue to be a priority for the U.S. Attorney’s Office." 

Murray said police executed a search warrant at the Nashua motel and found Michallyszyn with two handguns, nine rounds of ammunition, digital scales and "various drugs, including over 39 grams of fentanyl."

"Under federal law, it is unlawful to possess a firearm to protect one’s drug trafficking activities or the location from which one distributes narcotics," he said.

Michallyszyn is scheduled to be sentenced June 10.

When he lived on Fleet Street in Portsmouth in 2013, he was charged with drugging and raping a minor. Both crimes occurred in a wooded area adjacent to South Cemetery according to an affidavit by Portsmouth detective Robert Munson. His affidavit stated police learned about the crimes through a Crime Stoppers tip and the victim’s history of text messages substantiated the allegations. When he was arraigned, Michallyszyn told a judge he had a drug addiction and asked to go to a treatment center instead of jail.

“I’m not a danger to the community,” he said. “I gave the girl a low dose. I’m going to plead guilty to that. I’m not trying to back out.”

Joseph Bonavolonta, special agent in charge, FBI Boston Division, stated, "Today, Mr. Michallyszyn finally accepted responsibility for illegally possessing firearms to protect his stash of narcotics in pursuit of his drug trafficking activities. This case is another example of how the FBI will continue to work in lock-step with our law enforcement partners to eliminate guns, drugs and violence from our neighborhoods."
