According to the Houston Police Department, the deadly incident happened on Greens Road, near Imperial Valley Drive, at about 10:30 p.m.
Investigators said the woman, who was in her 20s, was in an argument with her significant other when she got out of the car and ran into the road.
"It's dark over here, and the driver did not see the pedestrian and ended up striking her. After he struck her, he turned into a parking lot nearby and called for help," Sgt. D. Griffiths said, adding that the woman died from her injuries at the scene.
HPD said there were no signs of impairment in the driver who hit the woman.
