An 18-year-old student at Copperas Cove High School was killed in a car crash Sunday afternoon. Investigators believe Sihyeon Ryu Stephans was headed northbound on US 183, drove off the roadway, overcorrected and skidded into oncoming traffic. Stephans was hit by another car and ejected from her car. Investigators say she died at the scene.

The memorial service has been set for Stephans on May 25 at the First Baptist Church. The service begins at 5 p.m.
