A 19-year-old Seattle woman died as a result of a two-car crash near Redmond on SR-202.

Two children sustained serious injuries as a result of the crash and were transported to Haborview Medical Center in Seattle, according to Washington State Patrol.

The accident happened at 4:29 a.m. on June 25. The woman, driving a black Ford Mustang, was exiting from a private circular driveway when a white Toyota Tundra struck the driver-side door of the car. As a result, the Mustang left the roadway into a westbound ditch and the Toyota struck a tree.

The driver of the Toyota, a 24-year-old male, was injured and transported for medical care.

The woman was deceased at the scene. Her two juvenile passengers, two girls who were 4 months old and 2 years old, are believed to be the woman’s children.

State trooper Rick Johnson said the 2-year-old was unrestrained and the infant was in a carseat that wasn’t properly restrained. The 2-year-old was ejected from the car.

An unsafe turn is listed as the cause of the accident. Other factors, including speed and impairment, have not been ruled out.
