SALINA — A mother was killed in a rollover accident near here Wednesday. But her two young sons, who were secured in their child seats, survived with only very minor injuries.

Just before 11:30 p.m. Edith Morrison, Vernal, was in a car traveling on I-70 about 20 miles outside of Salina when she drifted off the side of the road for an unknown reason, said Utah Highway Patrol trooper Cameron Roden.

The car rolled when she overcorrected. Morrison, who was not wearing a seat belt, was ejected and killed. Her two sons, ages 1 and 3, were taken to a local hospital as a precaution and released a short time later in good condition.

The cause of the crash was being investigated.
