The alleged gunman who killed one police officer and wounded six others in South Carolina is a 74-year-old disbarred lawyer, according to authorities.

Frederick Hopkins, a Vietnam veteran who’d bragged online about his marksman skills, is said to have opened fire on the officers while they were trying to serve a search warrant at Hopkins’ home in an upscale neighborhood in Florence, a city about 80 miles east of Columbia that is dealing with flooding from the hurricane of the same name.
