A woman is in custody in connection with a hit-and-run accident that left three teenagers dead.

Raquel Vasquez-Hernandez, 23, was arrested Saturday and charged with four counts of failure to stop and render aid.

The accident happened Saturday around 2:30 a.m. at the intersection of Woodbridge Drive and the South Loop feeder road.

According to Houston police, a white Chrysler 300 was speeding southbound on Woodridge and ran a red light.

The Chrysler then slammed into the side of a blue Chevy traveling eastbound on the South Loop feeder road.

The force of the crash sent the Chevy spinning, causing it to hit a light pole and then come to rest in the middle of the intersection.

According to investigators, there were six teenagers inside the Chevy, four men and two woman. 

Police say three of the teens inside the car were siblings on their way home from a party.

Two men and one woman in that car died at the scene. Two of those killed are the children of a Cy-Fair volunteer firefighter.

The three other teenagers were rushed to the hospital, one in critical condition and the other two in stable condition.

Police say there is no sign of alcohol consumption, but they are not ruling it out as the cause of this crash.

Investigators say they are still looking for another person who was in the car with Vasquez, but fled after the crash.
