Police are still investigating the murder of Calvin “Duper” Munerlyn, and they’re asking the public for help. As previously reported the 43-year-old Family Dollar security guard was shot in the back of the head after he refused to allow a customer’s daughter inside because she wasn’t wearing a face mask. An incident then ensued with the girl’s mother, 45-year-old Sharmel Teague, whose husband Larry Teague, 44, and her son Ramonyea Bishop, 23, later confronted “Duper” before killing him. Ramonyea is believed to be the one who pulled the trigger.
