Authorities say ice on the road may have been factor in the two-vehicle wreck that killed one person Friday afternoon in Cumming.The collision, which involved a 2002 Pontiac Firebird and a 2000 BMW, happened about 10:25 a.m. on Buford Dam Road near the Ga. 400 bridge.Jera Coen, 21, of 2920 Spot Road, was charged by the Forsyth County Sheriff's Office with one count each of second-degree vehicular homicide, failure to maintain lane and driving too fast for conditions.Sheriff's Capt. Tim House said the Firebird was traveling west, away from Market Place Boulevard and towards Hwy. 9, when Coen lost control and crossed into the path of the eastbound BMW.The BMW struck the side of the Firebird, injuring Coen and killing her passenger, 38-year-old Matthew Inman, House said. Inman has the same address as Coen, but their relationship was not clear."It appears to have been an unavoidable accident due to the weather," House said.Coen was taken to North Fulton Hospital with what were described as minor injuries. The driver of the BMW, 48-year-old Stanley Stong of 555 Lake Center Parkway, was not injured.Both lanes of the road were clear except for a strip of ice along the side.
