The Suffolk County District Attorney dismissed the charges against a Farmingdale woman accused of driving under the influence of drugs while her nephew was in her car. Officials said Karen Kregel was arrested in Medford on April 16 and charged with aggravated DWI and endangering the welfare of a child among other traffic violations. According to Kregel's attorney, the 44-year-old suffers from physical and mental disabilities that create the false appearance of drug-induced impairment.
