Another unit arrived and he drove the right way in the southbound lanes, trying to stop the female driver and that's when authorities say she slammed into a guardrail and crashed into a Jeep.
"An officer was going properly in the southbound side," said Lt. Phillip Munoz with the Houston Police Department. "He was putting out information on the radio and trying to get units out there to stop her but before units could get out there, it was too late. She already got into an accident."
Emily Cox, 20, died at the scene, according to police. The man in the Jeep was transported to the hospital for minor injuries.
Authorities believe Cox was intoxicated.
The accident completely shut down the Southwest Freeway northbound at Hillcroft for a couple of hours for the police investigation.
