A man from Connecticut has been charged after he allegedly caused a crash that injured a police sergeant while driving under the influence in February. David MacCracken, aged 53 and from Plainville, turned himself in and has been charged with possession of a controlled substance, operation of a motor vehicle under the influence, and second-degree assault (motor vehicle). The crash happened in the town of North Stonington, at the intersection of Route 184 and Jeremy Hill Road. According to the police, MacCracken hit a parked cruiser, which then hit Sgt. Mario Ritacco while he was conducting traffic outside of the vehicle. The officer was later flown to Rhode Island Hospital with serious but not life-threatening injuries. MacCracken is due in court on April 14. Witnesses reported that he was driving erratically and speeding around stopped traffic just before the crash. He suffered minor injuries and was taken to Lawrence and Memorial Hospital for treatment.
