NEW CITY, NY — A West Haverstraw man has been arrested after authorities seized more than a pound of fentanyl believed to have been shipped through the mail, according to law enforcement officials.
Investigators with the Rockland County District Attorney’s Office Narcotics Task Force and the United States Postal Inspection Service arrested Yamil Caraballo, 35, of West Haverstraw, New York on March 5.
Authorities said Caraballo is accused of possessing approximately 1.2 pounds of fentanyl and is suspected of receiving packages containing large quantities of the drug through the U.S. mail since December 2025.
Officials said the fentanyl seized during the investigation totaled more than half a kilogram.
“Postal inspectors relentlessly remove prohibited items and illegal narcotics, like fentanyl, from the U.S. Mail to protect both our employees and the public,” said Ketty Larco-Ward, who oversees the Postal Inspection Service’s New York Division. She noted that partnerships with local, state and federal agencies play a key role in preventing dangerous drugs from reaching communities.
Rockland County District Attorney Thomas E. Walsh II credited the multi-agency collaboration for the seizure and arrest.
“Justice is teamwork,” Walsh said in a statement. “Together, this collaborative work helped remove 1.2 pounds of fentanyl from Rockland County and led to the arrest of this individual. Lives were protected, and our community is safer today because of the coordinated work of our law enforcement partners.”
Caraballo has been charged in Rockland County District Court with criminal possession of a controlled substance in the first degree under New York Penal Law 220.21, an A-1 felony. If convicted, the charge carries a potential prison sentence of eight to 20 years.
Authorities said the investigation involved several agencies supporting the district attorney’s narcotics task force, including the Homeland Security Investigations, the Suffern Police Department, the Ramapo Police Department and the Haverstraw Police Department.
The Postal Inspection Service said its New York Division Contraband Interdiction and Investigations Task Force also includes officers from the New York City Police Department Criminal Enterprise Investigations Section and U.S. Customs and Border Protection.
Officials said the investigation remains part of broader efforts to disrupt domestic and international drug trafficking organizations that use the mail system to transport illegal narcotics.
