(CNN) -- Virginia State Police say they have identified the gunman who fired a high-powered rifle at four county deputies, killing two of them, officials said Monday, but they still don't have a motive for the shootings. Buchanan County Deputies Eric Dewayne Rasnake, 32, and Shane Earl Charles, 25, were shot multiple times after responding to a "larceny in progress" call at a salvage business in Vansant, Virginia, Sheriff Roy Foster said. The wounded deputies were able to crawl to a nearby residence for cover. Deputies Cameron Neil Justus, 41, and William Ezra Stiltner, 46, were shot with the same high-powered weapon after they rushed to the scene to help their fallen comrades, police said.
