A woman was killed on Sunday when she suddenly ran across the road in the Arden-Arcade area and was hit by a car.  Just after 8-thirty that night 54-year-old Laura Barnes of North Highlands ran across Watt Avenue just north of Barberry Lane...when she was hit by a driver travelling about 40 miles per hour.  Barnes was not in a crosswalk.  It's unclear if drugs or alcohol were involved, pending toxicology reports.
