(KAIR)--Authorities have released the names of the two people  killed Friday afternoon in a Leavenworth County head-on collision.

Leavenworth County Undersheriff Jim Sherley identified the victims as 89-year-old William Giles and 88-year-old Charlotte Giles, both of Cummings.

The wreck was reported shortly after 3:30 on U.S. 73 Highway, south of Roe Road in northern Leavenworth County.

Sherley said a preliminary investigation shows a 78-year-old Atchison woman, whose name has not been released, was southbound when for an unknown reason her Subaru Forester crossed the center line and collided head-on with a Dodge Journey driven by William Giles.

The driver of Subaru was transported to the University of Kansas Hospital in Kansas City for the treatment of multiple injuries.

The wreck remains under investigation.
