MANSFIELD - State police say a trooper conducting a routine check at the tourist center off Interstate 95 North discovered a couple in a car, and the woman was about to inject her arm with a heroin-filled hypodermic needle.

"What does it look like? Heroin," Rebecca L. Ford, 20, of Eastham, allegedly told Trooper Michael Tryon when he approached the car, Trooper William Fitzpatrick said Wednesday in Attleboro District Court.

Ford and the driver of the car, Jamison W. Rees, 19, of Orleans, were arrested Tuesday night by Tryon and Trooper Christopher Booth.

State police say the troopers found two heroin-filled hypodermic needles, 231 plastic packets of heroin bundled in rubber bands and 25 empty plastic packets inside the car.

The couple, described in court as drug users with criminal records, were recently charged in Orleans District Court with possession of heroin, and were released. In Attleboro District Court, they now face charges of drug conspiracy and possession of heroin with intent to distribute. Judge David Turcotte ordered them held in jail on bail.

Rees was ordered held on a pending warrant in another court and $2,500 cash bail, and Ford was ordered held on $1,000 cash bail.

They are due back in court Dec. 5.
