While performing ongoing investigative duties, Somerville Police Narcotics Officers observed what they determined to be a known heroin user along with four other individuals making their way through the streets of East Somerville towards Charlestown last Saturday afternoon.

The suspects’ vehicle was reportedly followed into Charlestown and their activities closely watched by police surveillance units.

While in Charlestown, two individuals were reportedly spotted entering the vehicle, after it had made a stop, and then leaving it a short time afterwards, police said.

The vehicle and was then reportedly followed back into Somerville where it eventually made a stop at a restaurant. The driver and passengers then reportedly entered the restaurant at that time.

Officers continued their surveillance and observed one female, McKenna Goodman, 19, of South Easton, entering the bathroom, later coming out with what they believed to be an obvious recent puncture wound on her hand, police said.

Another individual, James Amaral, 31, of Malden, appeared to police to be very unsteady on his feet, according to reports.

The group left the restaurant and once again traveled by car through Somerville until they were stopped at the intersection of Washington and Mt. Vernon Streets, police said.

At this time the suspects were questioned and searched by narcotics officers. Both Goodman and Amaral were reportedly in possession of small glassine bags filled with a brown powdery substance that officers believed to be heroin.

Goodman was placed under arrest and charged with possession of a class A drug.

Amaral was placed under arrest and charged with class A drug, possession of a class C drug, and possession of a class E drug.
