West Virginia State Police believe snowy conditions contributed to a head-on collision between two cars on W.Va. 9 that killed a 73-year-old Charles Town, W.Va., man and injured three people.
Paul Lambert Rowland was killed when the two cars collided near the intersection of W.Va. 9 and Wiltshire Road, about five miles west of Charles Town in Bardane, said Trooper Jose Centeno.
Rowland was a passenger in a car being driven by Timothy William Danner, 24, of Charles Town, Centeno said.
Centeno said the accident occurred about 3:48 p.m. after the driver of the second car, Judith Mary Brown, 30, of Martinsburg, W.Va., lost control of her 1994 Mazda truck, which skidded and crossed the center line. As she was trying to get back into her lane of travel, her truck struck Danner's Pontiac Grand Am head-on, Centeno said.
Brown was taken to Jefferson Memorial Hospital in Ranson, where she was listed in fair condition, Centeno said. Brown's infant daughter was in her truck, but the child was not hurt, Centeno said.
Danner and a third passenger in his car, Terry Lee Rowland of Charles Town, were taken to Winchester Medical Center in Winchester, Va.
Terry Lee Rowland was in serious condition at the hospital and Danner was in fair condition, Centeno said.
