The wreck happened around 3:30am on the North Freeway at the West Road feeder.
According to investigators, the 21-year-old suspect was driving a blue Nissan Versa north on the feeder when she rear-ended a Honda Civic.
The impact shoved the Civic into a concrete pillar and sent the suspect's car through a fence and into a business parking lot.
The woman then reportedly called a family member to pick her up from the scene of the crash.
Meanwhile, the driver of the Civic died after being rushed to an area hospital.
Police were investigating the hit-and-run scene when the woman returned. According to officials, her relative convinced her to go back.
The suspect was taken into custody for failure to stop and render aid. Police are awaiting the results of a blood draw. If they find she was intoxicated, she could face additional charges.
