The woman was trying to cross Ruddell Road near 19th Avenue SE at 6:45 p.m. when she was hit by an Acura sedan, according to Sgt. Shannon Barnes with the Lacey Police Department.
Barnes said the driver, a man in his 40s, immediately stopped after he hit the woman.
Police and medics arrived on scene moments later, but they were unable to save the woman, Barnes said.
The woman was not using a crosswalk. The driver is cooperating with police, and it does not appear speed or alcohol played a role in the crash.
