A Rhode Island and former Massachusetts woman was sentenced Monday in federal court in Boston for her role in a conspiracy to distribute and possess, with intent, 400 grams or more of fentanyl and 500 grams or more of a mixture or substance containing methamphetamine.
According to the Massachusetts Department of Justice, U.S. District Court Judge Indira Talwani sentenced 31-year-old Denise Guyette to 11 years in prison and five years of supervised release. Guyette pled guilty in September 2025 to conspiracy to distribute 400 grams or more of fentanyl and 500 grams or more of a methamphetamine-containing combination or substance. Guyette was indicted by a federal grand jury in February 2023, alongside co-conspirators Gerardo Garza and Nathan Boddie.
Guyette worked with Garza, Boddie, and others to trade numerous controlled narcotics, including methamphetamine, fentanyl pills, and cocaine, throughout Massachusetts, Rhode Island, and abroad. The drug trafficking group frequently used the mail to transport drugs from Arizona to Massachusetts, concealing them in parcels containing children’s things such as toy trucks, Halloween decorations, and Disney merchandise. Between May and October 2022, investigators recovered seven parcels containing more than 900 grams of methamphetamine, hundreds of counterfeit fentanyl tablets, and suspected dimethyltryptamine, a highly potent hallucinogenic.

Guyette was arrested on February 8, 2023, with nearly 6.5 kilos of pure methamphetamine and over 2,700 counterfeit fentanyl tablets weighing more than 300 grams in her bedroom safe. A digital scale, as well as various Rhode Island and Massachusetts driver’s licenses, Social Security cards, and credit cards in other people’s names, were discovered during a search of Guyette’s home.
Boddie and Garza both pleaded guilty. On September 19, 2023, Boddie was sentenced to 84 months in jail and three years of supervised release. Garza is awaiting his sentence date.
