(KAIR)--Two Atchison residents escape injury following a double vehicle Wyandotte County crash that sent a Kansas City woman to the hospital Sunday afternoon.

The Kansas Highway Patrol reports it remains unknown why, or how, the two vehicles collided, as both were southbound on I-435, just north of Woodend, when the wreck happened.

Injured was 45-year-old Shannon Williams, who was behind the wheel of a Ford Windstar involved in the wreck. She was taken to Providence Medical Center for treatment of her injuries.

The Patrol says she and her 17-year-old passenger were both wearing seatbelts.

Behind the wheel of the second vehicle, identified as a Chevrolet Camaro, was 19-year-old Shihan Cai, of Atchison. The Patrol reports neither Cai or his 18-year-old passenger, Noah Baniewicz, of Atchison, were hurt, and both were wearing seatbelts when the wreck happened around 4:45.
