Police say two officers were on patrol in East Patchogue when they observed two women sitting in a 2002 Ford Explorer in the parking lot of the East Winds apartment complex located on Montauk Highway around 9:30 p.m.
They say 26-year-old Tara Riley, of Medford, who was in the driver's seat, and 27-year-old Amanda Kosby, of North Bellport, who was seated in the front passenger seat, were both in possession of hypodermic instruments containing the drug.
Riley's 4-year-old daughter and Kosby's 5-year-old son were passengers in the back seat of the car.
Authorities say there were open bags of heroin on the front seat of the vehicle, and the women stated they had gotten high earlier in the day.
Riley and Kosby were each charged with two counts of endangering the welfare of a child, criminal possession of a controlled substance and criminally possessing a hypodermic instrument.
