The state Department of Consumer Protection Liquor Control Division has launched an investigation into the case of a Connecticut State Police Sgt who was charged this week for a DUI crash that injured a mother and her daughter in September.  The Department is looking into whether any Liquor Permittee in the state knowingly served an intoxicated individual, which is against state law.  While the spokeswoman declined to say whether regulators are investigating the Black Hog Brewery specifically, Sgt John McDonald was at a Trooper retirement party there before the crash.
