A state police sergeant who injured a woman and her daughter in a 2019 car crash in Southbury has resigned.  Sgt. John McDonald submitted his letter of resignation to state police Thursday. 

He was the subject of two internal investigations, one for the crash and the other for his work with the time management system while on administrative duty.  Those investigations have now been temporarily suspended.  McDonald’s decertification will prevent him from working at other police agencies. 

The car crash followed an alleged night of drinking by McDonald at a retirement party for a fellow trooper at Black Hog Brewing Co. in Oxford.  Security footage showed McDonald consumed at least eight drinks in about a 3.5 hour timeframe. McDonald pleaded no contest to two counts of reckless endangerment and was sentenced to a suspended six-month prison term and two years of probation.
