One of the operators of a popular YouTube channel promoting high-powered guns and explosives was found shot to death last week in northeast Georgia.

Keith Ratliff, 32, was found dead at 5:45 p.m. Thursday at his business on Hayes Road in Carnesville, said Franklin County Sheriff Steve Thomas in a press release.

Ratliff, of Frankfort, Ky., had been shot once in the head, and his death is a homicide. He had been dead for some time when the body was discovered, Thomas said. He was last seen alive Wednesday around 7 p.m.
