Vehicle strike now believed to have killed woman in Oglethorpe Co.

LEXINGTON, Ga. (AP) Authorities say they now believe a woman found dead alongside a Georgia highway more than a month ago was struck and killed by a vehicle. <br /> <br /> The body of 31-year-old Ashley LeAnne Watson was found Sept. 8 on the side of Georgia Highway 22, north of Lexington. <br /> <br /> Oglethorpe County Sheriff Mike Smith said previously that when deputies arrived at the scene, there were no obvious signs of trauma on Watson's body. <br /> <br /> The Athens Banner-Herald reports that an autopsy at the state crime lab revealed internal injuries substantial enough to cause her death. <br /> <br /> Georgia Bureau of Investigation Agent Jesse Maddox said investigators to not know whether foul play occurred. Maddox told the Athens newspaper that it's possible a motorist struck Watson and didn't know it. <br />
