A Sparks woman was killed early Saturday after her car struck a guard rail in Cockeysville.
Baltimore County police Sgt. Benjamin Yohe said that Tamara Sue Miller-Portesky, 48, was driving north on York Road at about 2:30 a.m.
Shortly after going through the intersection at Thornton Mill Road, the 2003 Ford Explorer crossed the center line and rammed into the guard rail. Upon impact, Miller-Portesky was ejected from the vehicle, and she was pronounced dead at the scene from her injuries.
