NORTH ADAMS — Two Northern Berkshire residents are facing drug charges after police said they tracked them driving back from Holyoke in possession of heroin.

Shannon Luczynski, 37, and Melissa Briggs, 38, failed to evade state police and were pulled over in Savoy and arrested after police said they discovered 174 bags of heroin.

The incident began when police in Berkshire County were alerted by state police assigned to the Northampton barracks that a Pontiac sedan had been spotted in "a high drug area" in Holyoke, according to the probable cause report filed by Trooper Scott Mason.

Troopers in the Holyoke area followed Luczynski and Briggs as they drove through the Northampton area in an attempt to evade police detection, according to the report.

State police stopped the Pontiac on Route 116 in Savoy for traveling 57 mph in a 45 mph zone, according to the report.

Police said they found 174 bags of what is believed to be heroin inside Briggs' pants. The estimated value of the drugs was $1,740.

Briggs, of North Adams, pleaded not guilty in Northern Berkshire District Court on Wednesday to single counts of possession to distribute a class A drug and conspiracy to violate drug laws.

Luczynski, of Clarksburg, who was driving, pleaded not guilty to the same charges, as well as a traffic violation for speeding. Both were released on personal recognizance.

The two are scheduled to appear in court Sept. 19 for pretrial hearings.

Luczynski also is facing charges after he was arrested July 18 in North Adams with 130 bags of heroin. He allegedly admitted to selling heroin to support his addiction.
