Two suspected heroin dealers were targeted for investigation by the Somerville Police Drug Control Unit last week.

Surveillance was established for the residence of Jessica Killeen, 26, at 173 Pearl Street. Killeen was reportedly observed making several short trips away from her home over the course of a single afternoon, at times taking brief rides in vehicles and being let out to walk back home, according to police.

Police officers at the scene noted that the same vehicle that had picked up Killeen earlier in the afternoon returned for a repeat occurrence of the previous activity, police said. After Killeen exited the car a vehicle stop was effectuated by police and the driver, Richard Fermin-Castro, 27, of  New York, NY, was approached for questioning, according to reports. Killeen was likewise intercepted by police as she attempted to walk back to her residence, police said.

Fermin-Castro attempted to put something in his mouth as he was confronted, according to reports, but was forcibly prevented from doing so, even as the suspect struggled with the officers on the scene.

Police reported that 27 clear plastic bags containing a brown colored substance believed to be Heroin was recovered from the interior of the motor vehicle compartment.

A search of Killeen’s residence reportedly yielded six similar bags, according to police.

Killeen was placed under arrest and charged with conspiracy to violate drug law, drug possession to distribute, and drug violation near a school or park.

Fermin-Castro was placed under arrest and charged with distribution of a class A drug, drug violation near a school or park, conspiracy to violate drug law, heroin / morphine / opium trafficking, and resisting arrest.
