A woman, her adult son and husband have been charged in the fatal shooting of a security guard who refused to let her daughter enter a Family Dollar store without wearing a face mask in Flint, Michigan. The argument began when the security guard, Calvin Munerlyn, told Sharmel Teague that customers needed to wear face masks in the store. Teague argued with Munerlyn before leaving. Teague's husband Larry and son Ramonyea Bishop later came to the store. Bishop pulled out a gun and shot Munerlyn. Teague has been arrested while police were looking for Larry and Bishop. A makeshift memorial featuring balloons and signs was set up outside the store in honor of Munerlyn, who was known as a fixture in the Flint community.
