CONCORD, N.H. – A Massachusetts man pleaded guilty in federal court to a drug trafficking conspiracy, U.S. Attorney Erin Creegan announces.

Roberto Ramon-Avalo, 27, pleaded guilty to one count of conspiracy to distribute controlled substances, specifically methamphetamine and fentanyl. U.S. District Court Chief Judge Samantha D. Elliott scheduled Avalo’s sentencing for November 9, 2026.

According to the court documents and statements made in court, beginning in early 2024, the DEA began an investigation into an unknown individual who was selling multiple-ounce quantities of methamphetamine in the Rochester, New Hampshire area. During the investigation, two DEA cooperating sources (or “CS”) communicated with another individual to purchase methamphetamine and fentanyl. Each time, Avalo traveled to New Hampshire to deliver the drugs at the agreed upon price. In December 2025, DEA obtained a search warrant for a suspected drug house in Boston that Avalo and another individual were using to conduct their drug trafficking activity. In the residence, DEA found items used to package and mix narcotics and approximately 5 pounds of methamphetamine and other controlled substances. After Avalo’s arrest, DEA found more controlled substances in a drug hide built into the dash of his car, including more than 200 grams of methamphetamine and more than 700 grams of fentanyl.

The charge of conspiracy to distribute a controlled substance carries a sentence of up to 20 years’ incarceration, not less than 3 years of supervised release, and a fine of up to $1,000,000. Sentences are imposed by a federal district court judge based upon the U.S. Sentencing Guidelines and statutes which govern the determination of a sentence in a criminal case.

The Drug Enforcement Administration investigated this case. The Portsmouth Police Department, Somersworth Police Department, and the New Hampshire State Police provided valuable assistance. Assistant U.S. Attorneys Matthew T. Hunter and Charles DeJoie are prosecuting the case.  

This prosecution is part of the Homeland Security Task Force (HSTF) initiative established by Executive Order 14159, Protecting the American People Against Invasion. The HSTF is a whole-of-government partnership dedicated to eliminating criminal cartels, foreign gangs, transnational criminal organizations, and human smuggling and trafficking rings operating in the United States and abroad. Through historic interagency collaboration, the HSTF directs the full might of United States law enforcement towards identifying, investigating, and prosecuting the full spectrum of crimes committed by these organizations, which have long fueled violence and instability within our borders. In performing this work, the HSTF places special emphasis on investigating and prosecuting those engaged in child trafficking or other crimes involving children. The HSTF further utilizes all available tools to prosecute and remove the most violent criminal aliens from the United States. HSTF New Hampshire comprises agents and officers from FBI, HSI, IRS, DEA, ATF, USMS, and DSS with the prosecution being led by the United States Attorney’s Office for the District of New Hampshire.
