NEWPORT — Newport police recovered marijuana, with an estimated street value of $56,000, after an investigation that culminated with a traffic stop Friday just before 8 p.m.

Marcos Cuadra, 46, of Nogales, Arizona, was charged with delivering marijuana in the amount greater than 5 kilograms, a felony.

In recent months, police have investigated a drug-trafficking organization based in Arizona that is transporting marijuana to Rhode Island, according to the police report. Police learned that UPS on Friday was delivering a 28-pound package from Tucson to a home in Providence.

Newport police and members of a Drug Enforcement Administration task force conducted surveillance outside the George Avenue residence in Providence as they awaited the delivery. Around 5:20 p.m., a UPS truck arrived, and Cuadra allegedly placed the package in a Nissan Rogue and drove to Newport via the Pell Bridge.

Police attempted to pull over Cuadra who, after traveling about an additional 75 yards, stopped the vehicle. He immediately told officers, “I have marijuana in the car, thought it was legal here,” according to the report. Cuadra added he was previously arrested for trafficking marijuana.
