A single vehicle accident last night on Highway 70 near Dogwood Valley Road in eastern Roane County claimed a life. The highway patrol says a 2001 Saturn operated by 60-year-old Richard C. Keil of Knoxville was traveling west and lost control in a curve. The automobile impacted a guardrail, came back across the road and went up an embankment striking several trees. It came to rest on its top. Keil, who was not restrained, passed away from injuries sustained.
