Wanted Massachusetts Trinitarios Gang Member Captured in Bethel, Maine

Portland, ME – The U.S. Marshals Service (USMS) in Maine, announce the arrest of Yonaidry Lascano Rosario, 24, in Bethel, ME. Rosario, a known member of the Trinitarios Gang, was wanted for 2 counts of Assault to Murder (Armed), Accessory After the Fact, Assault and Battery with Dangerous Weapon, Assault with Dangerous Weapon, and Firearm Carry without License. All warrants were issued out of the State of Massachusetts.

The USMS led, Maine Violent Offender Task Force (MVOTF), received a collateral lead from the USMS District of Massachusetts in April of 2025. For months, Maine Investigators conducted surveillance, interviews, and developed leads which finally resulted in a credible location for Rosario.

Thursday night, federal task force members surrounded a residence in Bethel, Maine and ordered Rosario to surrender. Rosario was identified and apprehended without incident. As a result of the arrest, a search warrant was also executed, resulting in firearm(s) and a quantity of drugs being seized by Investigators. Rosario was charged as a Fugitive from Justice, pending his extradition back to Massachusetts.

It is alleged that “Trinitarios” undertake efforts to dominate communities by intimidating rival gangs while trying to establish control over certain neighborhoods. As seen in previous charging documents throughout the country, “Trinitarios” tend to utilize violence, including murder, in furtherance of the organization’s goals and purposes.

The U.S. Marshal’s MVOTF received significant assistance from the FBI Maine Safe Streets Task Force, Oxford County Sheriff’s Office, Rumford Police Department, Norway Police Department, and the Massachusetts State Police Violent Fugitive Apprehension Section.

The District of Maine’s, Chief Deputy U.S. Marshal, Josh Taylor said, “This is simply the direct result of multi-agency collaboration between our federal, state, and local law enforcement partners who are dedicated and sharply focused on apprehending dangerous persons in Maine communities in order to safeguard our residents.”

The USMS, Maine Violent Offender Task Force is comprised of members of the U.S. Marshals Service, Maine Department of Corrections, Biddeford Police Department, U.S. Border Patrol, U.S. Immigration and Customs Enforcement, Maine National Guard Counterdrug Task Force, and the Coast Guard Investigative Service.
