WESTMINSTER -- Police found drugs and made arrests after three individual motor vehicle stops in town over the weekend, including one that resulted in a drug trafficking charge.

On Saturday, Vermont State Police conducted a motor vehicle stop with a 2001 Saab 95 on Interstate 91 northbound near mile marker 25 in Westminster for a marked lane violation and defective equipment.

While conducting an exterior scan of the vehicle with a state police K9, the K9 alerted to the presence of narcotics inside the vehicle. During a consent search of the vehicle, troopers located 690 bags of heroin under the rear seat cushion where the child of the operator, Eugenia Emerson, 33, of Springfield, was seated.

Emerson was arrested and transported to the Rockingham State Police barracks, where she was fingerprinted and photographed. She was issued a citation for trafficking heroin and order to appear in Windham County Superior Criminal Court on March 18.

Emerson was also issued a written warning for the defective equipment and marked lane violation. She was lodged at the Southern State Correctional Facility for lack of $5,000 bail.

On Friday, state police stopped a vehicle in Westminster for a motor vehicle violation on Interstate 91 northbound. Troopers had difficulties when they attempted to detain the operator, Louis B. Tobin, 26, of Fair Haven, due to suspicion of narcotics activity.

Tobin attempted to run away from a trooper but the trooper was able to take Tobin into custody after a lengthy struggle with the aid to an electronic control device known as a taser. The trooper sustained minor injuries due to the struggle.

Tobin was found to be in possession of 42 bags of heroin. He was also charged with attempting to elude and resisting arrest. He was lodged at the Southern State Correctional Facility for lack of $25,000 bail.

On Friday, state police conducted a motor vehicle stop on a 2001 Chevy Malibu on the Interstate 91 access road for a defective headlight. During a consent search of the vehicle, a misdemeanor amount of prescription drugs known as Suboxone, Mirtazapine and Diazepam were located. Suboxone is typically used for maintenance treatment of opiate dependence.

The operator Adam Cotley, 30, of Brattleboro, was arrested and transported to the Rockingham State Police barracks where he was fingerprinted, photographed and issued a citation to appear in Windham County Superior Criminal Court on March 18. He was also issued a written warning for the defective equipment and a civil violation complaint for driving with a suspended license.
