A Yorktown mother accused in a drunk-driving crash that killed her daughter?s 16-year-old friend is refusing to testify before a grand jury.

Police say the accident occurred while Ann Marie Ciarcia was driving home in September after a night of partying in Manhattan with her daughter and her daughter?s friend. According to police, Ciarcia drove the wrong way on the Saw Mill River Parkway and crashed into another car. Ciarcia and her daughter, Alexa, survived the crash. Emily Cornish, who was sitting in the backseat and not wearing a seatbelt, was killed. The accident also seriously injured the other driver, 49-year-old Ed Cook, of Yorktown

Ciarcia waived a felony hearing during Thursday?s brief court appearance. The district attorney told the judge she intends to present the case to a grand jury. Ciarcia could get nine years in prison if convicted of the charges of drunk driving and manslaughter. Despite the stakes, Ciarcia will not testify before the grand jury. Ciarcia remains free on $75,000 bail.
