A Massachusetts man with connections to a Dominican drug trafficking group has pleaded guilty in federal court to distributing fentanyl and methamphetamine in New Hampshire, according to an announcement from U.S. Attorney Erin Creegan.
Jose Luis Guerrero Nunez admitted guilt to one count of conspiracy to distribute controlled substances. Court records show that Guerrero Nunez acted as a leader in a Methuen-based organization that supplied significant amounts of methamphetamine and fentanyl in the New Hampshire seacoast region. In late 2023 and early 2024, he coordinated controlled sales of these drugs with undercover law enforcement officers and was recorded arranging future larger-scale distributions.
One alleged co-conspirator, Juan Carlos De Los Santos Romero, still faces charges. Three others involved—Carlos Alejandro Chevalier Santos, Eddy Mendez Carmona, and Luis Guerrero Cabral—have already pleaded guilty and received sentences.
The investigation was led by the Drug Enforcement Administration with assistance from several local police departments: Seabrook, Hampton, Portsmouth, Methuen, as well as the New Hampshire State Police. Assistant U.S. Attorney Matthew Vicinanzo is prosecuting the case.
This prosecution falls under Operation Take Back America, a national effort using Department of Justice resources to counter illegal immigration, dismantle cartels and transnational criminal organizations, and protect communities from violent crime.
