A former jail guard convicted of supplying the heroin that killed an inmate in 2002 faces new drug charges.

Christine Callahan, 43, of 3 Newton Court, Weymouth, was arrested Tuesday night in Quincy and charged with possession of oxycodone with intent to distribute. Police said the mother of three had her 11-year-old daughter in the vehicle with her as she tried to sell drugs in the Quincy Point section of the city.

Anthony Marchetti, 34, of Weymouth was an inmate at the Norfolk County jail in Dedham when, on May 7, 2002, he overdosed on heroin that Callahan had given him and died. Callahan was convicted in September 2004 of manslaughter, possession with intent to distribute heroin and delivering drugs to a prisoner. She was ordered to serve 15 months of a 2½-year sentence.

A Quincy police officer noticed Callahan’s SUV on Cleverly Court at 7:48 p.m. Patrol officer Matt  Tobin reported that a man standing next to the driver’s window of the Ford Expedition stepped back as he approached and the SUV left.

The officer stopped the vehicle after noticing that it had no front license plate, and saw Callahan moving as though she was reaching for something, Capt. John Dougan said.

Tobin checked the SUV for weapons and found what appeared to be a paper towel stuffed inside a black funnel. He found a plastic bag containing 19 oxycodone pills inside of the paper towel and a quarter of a Suboxone pill in Callahan’s pocketbook, Dougan said.

Callahan was scheduled to be arraigned Wednesday in Quincy District Court on charges of possession of oxycodone with intent to distribute, possession of a Class B drug as a subsequent offense, failing to display a front license plate and driving a vehicle without a valid inspection sticker, Dougan said.

Callahan’s daughter was turned over to her father, and the state Department of Children and Families was notified, Dougan said.
