Michael Mike Gray Grant, 72, was fatally shot in Winchester, Tennessee on May 6, 2021, at about 11:13 a.m. The shooting occurred at Speedy Self Storage on South College Street. Grant was sitting in the cab of his 18-wheeler; he frequently parked the truck at that storage facility.

Following the shooting, investigators identified his son, 52-year-old Michael Edwin Grant, as the sole suspect. The two men reportedly had argued before the shooting. The younger Grant allegedly drove to his mother’s house, confessed to the killing and said he intended to surrender. Officers arrested him while he was en route to the police station; he was booked on a criminal homicide charge at Franklin County Jail.

Does anyone have information about the events at the storage facility that morning or about Michael Grant’s routine there?
