Both drivers killed in a wrong-way crash last month on Kansas Highway 10 had about three times the legal amount of alcohol in their systems, according to Johnson County coroner reports released Thursday.

The Sept. 12 accident occurred when Eric Sill, 20, of Olathe, was driving eastbound in the westbound lanes of the highway, near De Soto. His car collided head-on with a westbound car driven by Kara Morgan, a 26-year-old Kansas University student, of Lawrence.

Final toxicology results indicate Sill, at the time of the crash, had a blood-alcohol content of .252, an amount more than triple the legal driving limit of .08 in Kansas. Morgan had a blood-alcohol content of .232 and signs of marijuana in her system, according to an autopsy report.

Both drivers, who were traveling alone, died at the scene from blunt force injuries to the chest, a medical examiner said in the reports.

Kansas Highway Patrol troopers had originally identified Morgan as the wrong-way driver, but they changed their report in late September.
