Woman dies in Dallas rollover crash

Police had to close several lanes of two Dallas highways overnight in Oak Cliff, while they investigated a rollover crash that killed one woman. 

It happened along Highway 67 northbound at Interstate 35E, around 4 a.m. When officers arrived at the scene they found the victim, who'd been thrown from her vehicle, on the road.  

The first responders also spent time searching the scene for a child because there was an empty car seat in the victim's vehicle. They did not find a child. 

Crash investigators are trying to figure out what caused the woman to lose control.
