On October 1, 2020, Lynn Marie Maher, 49, was working as a clerk at a 7-Eleven on Middletown Road in Waldorf, Maryland, when a single assailant entered and announced a robbery. According to investigators, the man produced a handgun and demanded money; after Maher emptied the register and showed him the till, he fired one fatal shot to her head. She died at the scene and the suspect fled with $249.69.

Charles County investigators described the suspect as a Black male of slender build wearing a white facemask, a dark hooded sweatshirt, jeans, and dark tennis shoes. Detectives later identified Gregory DeShawn Collins Jr., 22, as the primary suspect; he was located and arrested in Georgia on October 19, 2020, and returned to Maryland. DNA evidence and surveillance footage, which showed the suspect wearing a distinctive pair of blue jeans and blue tennis shoes, were used to link him to the crime.
