Lindsey Glass was arrested last week and charged with a misdemeanor violation of "sale to certain persons." The law prohibits the sale of alcohol to a "habitual drunkard or an intoxicated or insane person."
Authorities say 32-year-old Spencer Hight in September 2017 already showed signs of intoxication at the Plano bar before leaving for the home of Meredith Hight and opening fire.
Spencer Hight was shot and killed by responding officers.
Should she be held responsible?
