Madison police arrested three people Monday evening after receiving information about a delivery of heroin coming into the county.

The information suggested that three people were traveling to Ohio to pick up the drugs and bring them back to Madison, according to Senior Patrolman Joe Baker.

Baker began surveillance north of town and noticed a vehicle matching the description of the vehicle that was being used by the three people. Baker wrote in his report that the vehicle veered over the center line.

He did a traffic stop and found Tiara D. Turner, 18, of Madison, Justin Jones, 24, of Lexington, and Bradley Randall, 30, of Branchville, in the vehicle.

Sniffing outside the vehicle by K-9 Laykos suggested the presence of drugs in the car, Baker wrote. Turner had heroin in her possession, Baker said, and syringes were found in Randall's shoe and in a cigarette package near Jones.

Official charges will be filed today. Turner is expected to be charged with possession of a controlled substance, possession of a syringe and possession of paraphernalia. Randall and Jones are expected to be charged with possession of a syringe. The most serious charges are a Class D felony.
