Two Southern Oklahoma teens were killed Thursday morning in a head on collision in Murray County. Oklahoma state troopers say a pickup driven by a 16-year-old boy from Lone Grove crossed the center line on the Chickasaw Turnpike and hit an 18-wheeler head-on. He and his 17-year-old passenger, also from Lone Grove were trapped in their pickup and died at the scene. The truck driver is in stable condition.
