CHARLOTTE, N.C. — Six children were seriously injured in a rollover crash on I-485 in west Charlotte Thursday night, state troopers said. 

According to North Carolina State Highway Patrol, Shontavia Smith-Barber was traveling on the inner loop of I-485 near West Boulevard around 11:15 p.m. when she lost control of her 2010 Chevrolet Traverse and crashed. Troopers said there were nine people inside the SUV, including six children ranging from 4 months to 10 years old. None of the children were properly restrained, according to Highway Patrol. 

Smith-Barber told a responding state trooper that she fell asleep, which led to the crash. 

Troopers said the 4-month-old was in a car seat but it was not properly fastened inside the vehicle and an 8-month-old was being held in the front seat by a passenger. Everyone inside the SUV suffered serious injuries in the crash, with three of the children having life-threatening injuries.
