Police seized various drugs the alleged DUI driver tried to hide while being arrested.
A Warren County woman used heroin before crashing into a culvert and mailbox and fleeing, police said.
Charged is Alexa Montanaro, 25, of Great Meadows.
Hackettstown police were called at 6:49 p.m. June 27 to Grand Avenue for a reported hit-and-run crash involving a 2011 BMW striking a culvert, police said.
An officer found a car that matched the description provided by a witness a short while later along Grand Avenue and stopped it.
An investigation revealed Montanaro allegedly injected heroin into her hands while parked earlier in the Dairy Queen parking lot.
After being arrested and placed into a patrol car, officers found Montanaro attempted to hide 17 full folds of heroin, 20 empty folds of heroin and a syringe in the back seat, police said.
Montanaro also allegedly hid a syringe in her bra and possessed suspected marijuana in cellophane.
Montanaro is charged with DUI, possession of heroin, possession of under 50 grams of marijuana, being under the influence of heroin, hindering, possession of hypodermic syringe, possession of drug paraphernalia and various traffic and motor vehicle violations.
Montanaro was then sent to the Warren County jail.
