A traffic stop on Route 80 turned in a major drug bust involving more than 600 decks of  heroin, police say.

New Jersey State Police said they found the drugs after stopping a BMW sedan in Roxbury on Tuesday, and arrested Jamie Guadagno, 29, and passenger Unlee Sauveur, 32, both of Binghamton, N.Y. Troopers first found 12 wax folds of heroin and a marijuana cigarette inside the car and arrested Guadagno and Sauveur, according to police.

Once the duo arrived at the Netcong Station, police said, they found another 600 wax folds in the back of their cruiser where Sauveur had been sitting.

Sauveur was charged with possession of a controlled dangerous substance, possession of a controlled dangerous substance with intent to distribute, and possession of marijuana under 50 grams and is being held at the Morris County Jail on $20,000 full cash bail.

Guadagno was taken to the same facility on charges of possession of a controlled dangerous substance and possession of marijuana under 50 grams. She is being held on $10,000 bail.
