A doctor who taught at OSU's Medical School and his wife are dead, after a semi hit their car head-on.

New Mexico State Police said the semi crossed the center line on I-40, and hit Stephen and Susan Barnes' car head-on, killing them.

Troopers said the crash happened early Monday morning near Santa Rosa, New Mexico.

Relatives said Doctor Barnes had a private practice in Tulsa for years before he began teaching at OSU.
