A Darien man was cited with marijuana possession after a police dog detected a small amount of it during a car stop for a moving violation the morning of Thursday, Sept. 24, on the Post Road, according to Darien Police Sgt. Jeremiah Marron.

Guido Rodriguez, 53, of Mansfield Avenue, was issued a misdemeanor summons for possession of less than half an ounce of marijuana, Marron said.

At 9:30 a.m., an officer pulled over Rodriguez’s Grey Ford Edge after he made an illegal right turn off Ledge Road onto the Post Road, according to Marron. As he approached the car, the officer detected the odor of marijuana, but Rodriguez denied there was any in the car, Marron said.

When the officer told Rodriguez he wished to have K-9 dog Zulu do a “free-air” sniff of the car, Rodriguez admitted having some marijuana, according to Marron.

The dog located the small amount of marijuana in a medical dispensary bag inside the vehicle, but Rodriguez did not have a prescription for it, according to Marron.

Rodriguez was also issued a verbal warning for making an illegal right turn.
